    Building Competition 2017

    Building Competition 2017 By Evan and Austin

    Task: Find the best robot design

    The games have begun and it’s time to build. So that’s what Austin and I did. A war had been declared. Legions of the indentured collided on the battlefield. Millions were slaughtered during this new age armageddon. Austin had his army. I had mine. Two different ideas to do the same task: lift glyphs into their correct positions. A simple job but one that caused a rift in...

    Super Regionals Booth Design By Caitlin, Austin, and Omar

    Task: Design a theme and layout for super regional pits

    A year or two ago Imperial advanced to Super Regionals, bringing along a few Iron Reign members. While teams get excited and have a lot of fun at Regionals, it's nothing compared to the displays found at super regionals. We've grown into our cyber-Roman theme this season, and Omar is currently working on a logo to match our new color...

    Building the Fly Wheel Launcher

    Building the Fly Wheel Launcher By Jayesh, Omar, Darshan, Evan, Tycho, and Max

    Task: Create a particle launcher with a higher scoring rate

    The first particle launcher we saw by another FTC team was actually a crude flywheel and rail design back in October where the rail was a cut up PVC elbow. Back then we considered a number of different designs including impact launchers, catapults, flywheel + rail systems and dual flywheel shooters like our sister team built. We decided to go with a catapult design because Max...

    Fly Wheel 2 - Fly Harder By Max

    Task: Create a backer rail to guide the particle as it fires

    Our work on the flywheel design has been an effective proof of concept, and now we need to work it in to the rest of the robot. However, just like with the catapult, there’s a couple issues to iron out before all the pieces can start moving in a way that doesn’t make the robot implode.

    Most notably to the 3D modeler in me, I fear that our current...

    Introducing the New Particle Accelerator

    Introducing the New Particle Accelerator By Max

    I was going to make a Windows 10 joke but then we stopped using the catapult at version 8.

    Task: Design a flywheel for a new system replacing the catapult

    So while our catapult was good, we needed something better. It frequently missed and had other issues due to it being dependent on elastic bands that can lose tension over time. It would occasionally miss balls from areas it would usually be able to shoot from. As well,...

    Motor Controller Mounts

    Motor Controller Mounts By Ethan, Darshan, Max, and Tycho

    Task: Prevent static shocks to our robot

    Throughout the year, we've dealt with static issues with our robot, as shown here and here. And, now that we've pretty much gotten autonomous and the lift out of the way, the static was our only remaining issue.

    To prevent the static shocks, we needed to isolate the motor controllers and other...

    Cap Ball Lift

    Cap Ball Lift By Omar, Jayesh, Darshan, Evan, and Max

    Task: Build a lift to try cap-ball scoring

    Although we're confident in our robot's ability to shoot balls and press beacon buttons, we decided that in order to be competitive, we should try to score the cap ball. The lift would have to be strong enough to lift the surprisingly heavy ball, but also not take up too much space. Our robot, as like every year, is very close to the 18 inch size limit in all directions, so we...

    Mapping Out Autonomous

    Mapping Out Autonomous By Janavi, Tycho, Omar, Evan, and Darshan

    Task: Mapping Out Autonomous

    To tell the robot how far to move forward we had to calculate our motors RPM. We did this by telling the robot move to 10 rotations forward and calculating how far it travelled. After he RPM we created a model field upon which we designed a set path for the robot during autonomous. One path for red and then one for blue....

    Fixing Faulty Encoder By Tycho and Jayesh

    Task: Fix a faulty encoder on our robot

    This shows a test of our encoder issues. It might have been a month ago that we noticed a strange behavior in our autonomous code when the robot was moving forward at low speed. It would curve to the right when we were telling it to go straight. We probably would have noticed the problem...

    Beginning the build for the Cap Ball Trapper By Jayesh and Omar

    Task: Give Deadshot flexibility in end game scoring by designing Cap ball launcher

    One of the issues we saw in Arkansas was in the lack of flexibility we had in terms of the end game. We efficiently scored balls and beacons, but when our teammate for a specific match could do the same, we lost possible points scored. This led us to conclude that a Cap Ball Trapper,...

    Task: Make some changes to the catapult bowl

    The apocalypse is at hand.

    Chaos reigns as the world is thrown into peril; whole nations are thrown into anarchy by the second; and the superpowers of the world, once bitter enemies, have no choice but to band together as a horrid product of our own hubris, a threat more devastating than any which mankind has ever before seen, appears to put a grisly end to humanity:

    Designing Button Pusher

    Designing Button Pusher By Darshan and Omar

    Task: Design potential beacon scoring mechanism

    Up to this point, we hadn't given much attention to a beacon scoring mechanism that we could use in both autonomous and tele-op. At the scrimmage we learned that scoring the beacons was almost vital to winning the match, and we couldn't do that. We rigged up a short u-channel on a plate and attached it to our robot, hoping we could just ram...

    Robot Frame and Rewiring

    Robot Frame and Rewiring By Jayesh, Omar, and Evan

    Task: Build a frame to increase available surface area on robot to rewire current configuration

    The wiring, which had been on the robot, had been a constant issue. The wiring tangled, interfered with the scoring mechanism, and led to some inefficiencies in electrical output. In order to increase the available space to reconfigure the inner workings of the robot, we built a second testrix layer, which also conveniently serves as a handle.

    Final Catapult

    Final Catapult By Ethan, Evan, Omar, and Jayesh

    Task: Finish up the catapult before Arkansas

    Today marks six days until Doomsday (AKA Little Home, Arkansas), so we needed to finalize everything. For the catapult, Jayesh and Omar fixed my catapult "fixes". However, with the new fixes, the catapult was more powerful, and required recalibration. To adjust to the new fixes, we removed the old stop-mechanism, and replaced it with a wooden one that stops it on the 2nd level of...

    Catapult Upgrades By Max

    Get Nostradamus on the horn, there’s a new prophet in town.

    Task: Imbue the catapult bowl with infinite power

    As I predicted in the article about the first version of the catapult bowl, it’s gonna need a rework. There’s enough room for the catapult system and the conveyor system to fit together on the robot, but the lip of the bowl is too high for a ball to roll into the slot. This is a tough issue to solve: we’ll have to slice a chunk...

    Catapult Unfixes

    Catapult Unfixes By Ethan

    Task: To bring the catapult within size limits and improve it

    What Actually Happened: Abject failures

    So, the original catapult, when not stuck, performed pretty well at the scrimmage. However, since we opted not to measure our robot at the scrimmage, we didn't realize that our robot was not within the FTC size limits. When measured after the fact, it was 18x19x20 in x, y, and z axes respectively, due to the catapult's position on the robot. To rectify this, we decided to cut the catapult down,...

    Intake System Improvements

    Intake System Improvements By Caitlin and Janavi

    Task: Replace rubber bands with smaller versions and add wider intake area

    New intake area is wider than before


    At the Scrimmage we noticed that the rubber bands would get tangled as they rubbed against the underside of the catapult bowl, and so didn't reach as far down at the bottom. We untangled them before each match but decided to test out the smaller ones when we had the chance at...

    Parasyte

    Parasyte By Jayesh, Omar, Darshan, Caitlin, and Max

    Task: Design a collector for the balls

    We've spent the last few practies creating a ball collector. The idea was to have our track with the gripping rubber bands reach from the bottom of the robot to our 3D designed ramp. The path would guide the balls to a higher position on our robot to the launching mechanism. We needed to adjust the correct orientation of the support beams guiding the balls, needing...

    The Robot is a Nautilus Now

    The Robot is a Nautilus Now By Max

    Task: Make a conveyor shaft to guide particles to the catapult

    We’ve thoroughly proven that the tread of rubber bands is an effective method of ball collection, but as of yet it can only move the balls along the ground. We’ll need a way to move them upwards to the catapult bowl’s level. While we could use another motor to push the particles up and over the belt, it could get caught and we’d rather not take up another motor port. We decided...

    Launching Mechanisms Pt. 2

    Launching Mechanisms Pt. 2 By Ethan

    Task: To improve upon launching mechanism designs

    Catapult

    First and foremost, we now have one completely functional, terrifying, catapult. The motor mechanism is cannibalized from our sister team's attempt at a catapult, which broke apart on testing.

    Stabilizing Our Driving Base

    Stabilizing Our Driving Base By Jayesh, Omar, Max, and Darshan

    Task: Stablize Meccanum wheel base so the driving is more stable and consistent

    Our Meccanum wheel base idea started off on a shaky note. While we had a good amount of success in the tass we wanted to complete, like driving right or let without turning the entire robot, including the basic driving functions. However, as we went on with testing, we found that over time, the force the meccanum wheels...

    Ready the Artillery

    Ready the Artillery By Max

    Task: Design a bowl for our upcoming catapult system

    We've been experimenting with catapult systems for a little while now, but we're still sorely lacking one of the core ingredients of any catapult system: the ability to throw things. I mean, technically we're lacking the ability to hold what we're trying to throw, but it's the same effect.

    In any case, it's an issue we have to deal with, and our solution is good ol' nylon. I went through a few designs for a...

    Launching Mechanisms

    Launching Mechanisms By Ethan

    Task: To build a launching mechanism for the particles

    For the 2016-2017 season, particle scoring is really important. During autonomous, balls that are launched into the center vortex earn 15 points each, and balls that are launched into the center vortex earn 5 points. If done quickly enough, the particle scoring can negate most of the advantages another team has - just 8 particles scored during the driver-controlled period is equivalent to scoring all 4 beacons. With a good scoring mechanism, the only thing that your team...

    Need for ZTE Speed - The Movie - The Game By Max

    Task: Make a case for the ZTE Speed controlling the robot

    While we are still in the early stages of design and it's not wise to make a permanent decision about where the robot's controlling phone will be, we can't let it float freely around the robot like a brain in a jar for much longer or it'll start getting caught in the developing systems. Normally, we could solve this easily by drilling a few holes in an off-the-shelf...

    Building the Robot Base

    Building the Robot Base By Jayesh, Omar, and Darshan

    Task: Design and test implementation of a driving base

    We have spent the last few practices formulating a new driving base for our robot this year. We went through various possibilities: tank-based drive using both tracks and the omni-regular system (both of which are systems that we have utilized in previous years). However, both systems showed inefficiencies with this year's competition. We decided to go to a system using mainly Mecanum...

    Geb Fixes and Adjustments By Jayesh, Omar, and Caitlin

    Task: Prepare Geb for competition and get it into running condition

    With all of the large projects and events that Iron Reign have been commiting to (with more still to come), we have unfortunately been neglecting Geb and as we came to find a few weeks ago, many of the running parts that give us the majority of points in competition were falling in disrepair. We found that the tape measure system...

    New tread material test

    New tread material test By Caitlin, Tycho, Max, and Evan

    Task: Initial tests for new tread material

    The standard Tetrix treads and tread inserts aren't nearly as sturdy as we would like. When they snap it's a real effort to put back together stretched over the idlers, and the inserts peel apart, bringing our traction down. The new material is a rubber conveyor belt material from Andymark, and the underside track chain is 3D printed in nylon to mesh with the...

    Fixing Up Our Climber and Trough Attachments By Jayesh, Max, and Omar

    Task: Replace servo on CliffHanger with a motor

    At both competitions we've been to so far, we've noticed that the servo that controls the cliff hanger's elevation often stresses and heats up due to the strain being put on it, especially near the end of the match. It has already scorched quite a few of our fingers. To remedy this, we decided to replace it with a...

    Pushing my Buttons

    Pushing my Buttons By Ethan and Max

    Task: To build a button-pusher for the beacon

    Today, we realized that the tape-measure attachment that's supposed to push the buttons on the beacon could have multiple functions instead So, we designed an attachment to the tape measure that can push any buttons, including people's. Max designed it in PTC and then printed it. We have yet to actually test it on the robot, but it works in-hand.

    This is just our first design, and it has not...

    The Double-Wide Experiment

    The Double-Wide Experiment By Jayesh, Max, Dylan, and Evan

    Task: Strengthen our tape-measure climber against folding and sideways forces

    Our tape measure is constantly under stress, which usually isn't a big problem if the driver is positioned with a straight 90 degree angle, but when twisted can result in cracks.

    While our tape-measure design worked decently at our competition last week, with multiple mid zone scores and one high zone score, we are going to need more consistency to be a valuable ally in our matches. At...

    Conveyor belt By Jayesh, Max, and Darshan

    Task: Create continuous method of scoring blocks

    Since we have a semi-reliable form of going up the ramp (which we are working on to make closer to 100% efficiency), a priority for our team robot-wise is to establish an effective method of scoring blocks. We've designed a preliminary model with our old plastic trough that uses a conveyor belt made of fabric and foam sewn together that we tried to use before but decided not to. The foamy...

    Tape Measure Attachment

    Cliff Hanger - Tape measure based climber By Trace and Max

    Task: Creating an attachment to climb the mountain


    We have recently been working on a new approach to climbing the mountain. Our strategy so far was to have one system customized for climbing the mid and upper mountain (Churro Climber), and a separate system for climbing the cliff (Crossbow Grapple). The Churro climber system was beginning to work but it was floppy and we were thinking about stiffening the nylon extensions with...

    Prototyping and Making the Flipper By Jayesh, Omar, Darshan

    Task: Design an apparatus to deposit the climbers in the beacon bucket.

    One of the methods to score in this year's competition is depositing the two climbers in the bucket behind the beacon. This being relatively simple, we decided to concentrate this practice on creating something to get us these easy points. We discussed possible ways to deposit the climbers and came up with a design that used some of the scoring mechanism we already had on our robot. The idea was to...

    Rebuilding the Churro Climber System

    Rebuilding the Churro Climber System By Omar, Darshan, Max

    Task: Fix bending axle on churro climber permanently

    After further testing of the churro climbers, we noticed that the axle the gear is rotating on had been bent severely due to the strain on it of the arms pulling. If we left the axle as it was, it might wreck something else later and become unusable, so we tried to figure out a way of creating something that served the same function as the axle but wouldn't bend as easily. We decided...

    Slide Lock By Max

    Task: Model a part to keep the slide from going too far forward

    Since we mounted the beater bars on a slide, we have been keeping them from going too far and falling off their rails either by obstructing them with a couple of bolts or with a bent piece of steel wire, but neither method is fool proof. The wire can get bent out of shape as the slide moves forward and collides with it, and...

    Climber Restraint By Max

    Task: Model a part to keep the churro climber cable ties on path

    As we continued to work on the churro climber mechanism today, we decided that the cable ties bowing out would be a big issue that needed fixing. By making a small guide piece, we could ensure that the cable tie actually extends from the front of the robot instead of flopping around like overcooked spaghetti on the other side. So, I've made a rather...

    Improvements to Churro Catcher and Ramp By Jayesh, Caitlin, Omar

    Task: Make improvements to Churro Catcher and Ramp and make blog more accessible

    Iron Reign held our first of two meetings before the New Year season to concentrate on improving our main designs to ensure they worked as expected. Starting with our Churro Catcher, we found that as the motor moved the two arms down, the tension in the two churro climbers was two low to actually push out the latches forward from the robot. We built two small metal segments...

    Task: Improve and fix our Churro Catcher + finalize design for trough

    The team met up on Sunday and we focused our meeting on finalizing our trough design and making our churro catchers usable. Beginning with our trough prototype, we put in an angled metal piece to the main box compartment and shortened the height of the box. This height was specific to the height of the blocks, allowing us to shave off blocks that become stacked upon those that we've already collected and...

    Churro Hook

    Churro Hook By Max

    Task: Model a part to help the robot climb the churros on the mountains

    Most of the big-value items in terms of points have to do with the mountains, so climbing mechanisms are a must have. Since the tank treads have problems scaling the churros on the middle and upper mountains, we need another way to pull the robot higher. Our solution was to put hooks on the ends of long, heavy-duty cable ties that we could...

    Task: Prototype the trough using materials such as cardboard to give us a baseline

    '

    The team had a meet before the busy Christmas period to focus on the main part of of our scoring mechanism: the trough. We discussed possible courses that would be easiest for us to score points and code at the same time. We went through multiple ideas of how the trough would work. One idea was to have our trough consist of rotatable base to account for...

    Improving the Catcher Design

    Improving the Catcher Design By Dylan, Darshan, Omar, Jayesh, Evan, Alisa

    Task: Add Improvements to the Catcher Design

    Today our team worked on improving the methods of capturing and holding blocks and balls. Our first design involving zip ties had major difficulties including that it had little strength to pull objects in. For this reason, we redesigned the beater bar using a 3-D printer that had stronger materials to capture materials along with frictionless tape which did not cause the blocks to become stuck. Through our tests we can see that...

    Task: Model a part that lets us hold back the slide with a trigger to release it

    The beater bar mechanism was put on a slide so that we could restrain it until some point during the match, but we had yet to actually build a restraint and trigger to serve this purpose until now. Since the mechanism would likely include rubbing pieces and need customized parts, we chose to model and 3D print the part in...

    Task: Think about our robot's design both for now and for the future


    Today, I decided to list our different options when it comes to design and on how much effort they would take on a numerical scale from 0 to 7. 0 means no effort would be needed at all (none of our options are currently here), and 7 means that the option is almost not practical based on the work we'd need to put in, but would be a huge benefit on our...

    Design and prototype a churro latch mechanism By Caitlin, Darshan

    Task: Design an alternative churro climber mechanism

    Currently Max and Tycho are working on a beater bar 3D part that is stiff enough to pull in blocks, and will hopefully double as a churro catcher when spinning. However, since the parts take 4 hours per set to print, and are harder to rapid-fire test and change and tweak relative to some other options we're going for other options till they're tested. The churro catchers help us to secure holding up the ramp but...

    Hell On Reels By Max

    Task: Make a prototype grappling hook of doom.

    As the point values make clear, managing to get the robot to hang on the end of the "cliff" is likely worth the effort. As such, we've worked on making a strange grappling-hook type contraption to pull the robot up. This first version works rather like a crossbow. A telescoping fishing pole has its largest loop hooked up to a long "bolt" which extends beyond the pole to a bungee cord tied to a pair of arms on...

    Addition of Beater Bar to Robot By Omar, Ethan, Darshan, Caitlin

    Task: Fix and alter robot to include sliding beater bar

    Since the robot's last run, several fixes and adjustments had to be made in order to make the robot operational again. All we had to do was tighten a couple of bolts, so it wasn't that big of a deal. We'll probably have to do a quick check from now on to make sure nothing's falling off. Afterward, we set to using the same beater bar we used last year (the first...

    Task: Improve our 3D Printable case for the Adafruit BNO055 IMU

    Last week I designed a case for our IMU sensor in Creo and wrote up how it could be improved. I've fixed most of those issues and we are ready to share the results. There is one version with Tetrix hole spacing and another that works for Actobotics channels. Either can be used with aluminum extrusions though you might have to drill out the mounting holes depending on your bolt size.

    I Hate Tread Inserts By Omar

    Task: Insert grips into alternating treads to boost traction of driving system

    I am so done with these treads. For the past three hours I have worked to soak the treads and tread inserts in dish soap. *takes deep breath* The process is painstakingly slow and also literally painful. The process itself seems simple but after soaking both pieces the insert must be pushed in with a considerable amount of force. This is not user friendly and is not what the company...

    Task: Design a new build platform more suited to this year's challenge

    Since the robot game for this year came out about a week ago, we were thinking about which kind of drive system would work best for the challenge, which mostly involves climbing. Some of the concept we came up with were rocker bogies, rubber-banded tires and a tank drive with treads. Since we already had the preliminary design started for a tank drive, I started modeling that.

    Task: Discuss robot design

    Now that the game has been released, we as a group discussed the different amount of points per each possible game strategy that would give us the most ample amount of points during the given time limit. We also discussed the different ideas on the tracks and wheels that are possible for our design. The arm attachment was discussed for the grabbing of the highest mount of the mountain which would give us the...

    Task: Create preliminary designs for a new robot using a new build platform

    After we got the new mechanum wheels, I had to start thinking about a new design that would be able to use them.

    Reflections

    Not much progress was done on the design based on the mecanum wheels, but I remade part of the design based on our old robot from previous years. We will build one robot based on our proven omniwheel-drivewheel-omniwheel nacelle design, only...

    Task: Create preliminary designs for a new robot using a new build platform

    Today I started making new designs for a competition robot based on extrusions and the new software platform.

    Reflections

    I decided to make two different possible designs, one based on our robot that we had used for the past few years with 1 regular wheel on each side in between two omni wheels, and another based on our sister team's newer platform, which had one standard wheel on each corner. After...
