    Autonomous Updates, Multi-glyph

    Autonomous Updates, Multi-glyph By Abhi

    Task: Score extra autonomous glyphs

    At super regionals, we saw all the good teams having multi glyph autonomi. In fact, Viperbots Hydra, the winning alliance captain, had a 3 glyph autonomous. I believed Iron Reign could get some of this 100 point autonomous action so I sat down to create a 2 glyph autonomous. We now have 3 autonomi, one of which is multiglyph.

    I made a new methods called autonomous3(). For...

    Upgrading Kraken

    Upgrading Kraken By Abhi

    Task: Update CAD model

    With FIRST Champs right around the corner, we needed to update our CAD model to match our current Kraken. After all, Kraken can't be lackin' any features. I decided to reopen Creo and make some modifications.

    One of the most important things I needed to put on was the Relic arm. After planning on it for the whole season, we finally finished it recently. I...

    Engineering the Flag Holder

    Engineering the Flag Holder By Abhi

    Task: Find a place to put the flag

    When we went to Super Regionals, we forgot about where to put our flag with the new design. That led us to strapping a zip tie to a side shield, ruining the aluminum aesthetic. We decided we need a specially designed part to put our flag in since duct tape didn't look nice (we're classy like that). I embarked on a mission to create a...

    Gripper Physics Diagrams

    Gripper Physics Diagrams By Ethan

    Task: Describe the physics of the gripper

    We always struggle a little with describing our robot to the judges. So, this post will be the third in a series of posts describing the physics of our robot (four if you count the coefficients of friction). First, we have the free body diagrams of the gripper.

    Next, to further describe this, we created an expiriment in which we determined the maximum...

    Progress of the Octopuckers Over Time

    Progress of the Octopuckers Over Time By Ethan and Tycho

    Task: Chart the progress of the octopuckers over time


    This design was too rigid, we overlooked the fact that triangles tend to be the strongest shape, and therefore this octopucker wasn't as compliant as we wanted, damaging the blocks.

    This design was really good, and we used it for 3-4 tournaments. Our initial design of these wouldn't damage the blocks significantly at the levels...

    Relic Arm Design

    Relic Arm Design By Ethan, Abhi, and Shaggy

    Task: Design and implement a new Relic Arm mechanism

    At the North Texas regionals, we realized that if we really want to go further in the robot game, we need to significantly improve. Part of this is designing the new grabber-flipper system detailed in a later post, but another good way to score points is to score the Relic. So, we designed v1 of the Relic Arms, as detailed in this post....

    Grabber V5. Diagrams and Pictures By Austin

    Task: Implement the new grabber system and record how it works

    So, we've been talking about our new gripper system for a while - we've made prior 3D models and started it, hoping that we'd have it done by the Oklahoma Regional, since that was sort of a low stakes tournament for us. Unfortunately, we didn't get it just in time, so we had to go back to the basic...

    Intake Stars By Tycho

    Task: Improve the functionality of the gripper

    Our grabber is good, but it isn't achieving 100% of the potential it could. One thing we're doing is creating the Grabber V.5 previously blogged about, but we also want to increase the speed of the grabber in other ways, in order to get every single bit of performance out of our robot, since we want to really impress at Supers. So, we designed star-grabbers. The purpose of...

    Last Minute Robot Fixes

    Last Minute Robot Fixes By Ethan and Evan

    Task: Add last-minute design changes to the robot

    It was a temperate night. The waning moon shone overhead, a blazing reminder of the continuity of time, for as the moon dipped lower in the sky, our precious little time until the tournament dripped away. Under this oppressive, singular symbol, we labored, trying to outpace the continual march of time.

    Over the past week, we had worked tirelessly on the robot. In...

    Designing Grabber V. 4.5 By Ethan, Evan, and Austin

    Task: Build an Updated Grabber System

    So, we probably won't finish both the Grabber V.5 and the Flipper designs by the North Texas Regional this Saturday, but we really need to improve our grabber system so that we have a chance of doing well in the robot game. From our last post-mortem, we decided that while our grabber performed *well*, it obviously could have been better. So, in...

    Task: Develop Conveyor System 2

    After analyzing the lack of speed from our last competition, we decided to continue the journey of attaching the gripper arms to a conveyor belt as previously designed. To do so, we realized that we needed to utilize the REVolution system to make the grippers work better. Also, we needed two points of attachment for our robot after seeing that one didn't work with the first version of the...

    Building a new chassis By Karina and Janavi

    Task:

    Janavi and I have started to build a new chassis for Kraken 2.0., modelled after Kraken’s current chassis.

    First, we had to measure the chassis of Kraken, then cut REV rails to these measurements. Lastly, we assembled the pieces to look as it does above.

    With this being the first build project Janavi and I have taken the lead on, we had to have some help...

    Flipper+ By Evan, Abhi, and Janavi

    Task: Build a new glyph scoring system

    As the season wears on, the robot game looms over Iron Reign since the bot we built scores only a fifth of the world record. To lessen the gap, we continue to invest in the flipper system I contrived earlier on in the season. As of late, we’ve furthered the project by building a chassis for it to rest in. It’s a slightly modified version of the one...

    Friction Coefficients of Various Materials

    Friction Coefficients of Various Materials By Ethan

    Task: Test Friction Coefficients of Various Materials

    Introduction:

    Iron Reign has used many different materials in years past. In those years, we usually preferred materials which were more durable. We started with ABS, but while hard, it was relatively brittle. We attempted to use Filoflex and Ninjaflex, and they were more durable, but too soft. Finally, we had used nylon for the past seasons, as it was extremely durable but...

    The Grabber V. Kraken

    The Grabber V. Kraken By Austin and Evan

    Task: Build a new version of the grabber

    One of our issues with the previous iteration of the gripper was the fact that the material that coated the actual pincers weren't even and would often lead to blocks slipping from the bottom of the gripper and falling out. Our solution to this was to retest materials and in this process we decided to try our hand at 3D printing...

    Fixing the Robot Chassis

    Fixing the Robot Chassis By Austin

    Task: Redesign the robot chassis, fix issues

    When we designed our new grabber with the octopuckers, one of the variables we neglected was the width of the new grabber once assembled and resting. After the grabber was completed it’s width was actually greater than that of the housing bay we had built into the current drive train, so to get the grabber to fit we actually had to widen the bay....

    Chassis Model

    Chassis Model By Abhi and Janavi

    Task: Use Creo Parametric to CAD the chassis

    After making significant development on our robot, we decided to model it. So far, we have developed the chassis of the robot seen below

    To develop this, many types of contraints were used.

    The entire model is dependent on this tetrix bar. The bar was constrainted using the Default feature since it was the base of the model. To this, the lift...

    Introducing Kraken

    Introducing Kraken By Abhi and Tycho

    Task:Design the robot model

    We have finally completed assembly modeling Kraken, Iron Reign's Relic Recovery robot. Named after the sea creature due to the robot's OCTOPUCKERS, Kraken stands as a fierce competitor in FTC.

    To the chassis, we added the glyph system mounting. We first designed a linear slide replica and constrained that to a small TETRIX U connector piece which attached to the REV rail base. On the other side...

    REVolution Narrow Bearing Washer

    REVolution Narrow Bearing Washer By Tycho

    Task: Power to the REVolution

    Washers can be used as spacers. They are also used to smooth out the rough top layers. Keep the bed very clean and smooth and the bottom surface of parts should be very slippery against other nylon. Put these in between the rough top bearing surface of one part (with rough surface facing rough) and the smooth bottom surface of the next part, and the friction...

    REVolution Rail End Cap

    REVolution Rail End Cap By Tycho

    Task: Power to the REVolution

    End caps are stops placed at the end of a REVrail. Five of the holes are for M3 bolts that can be screwed into the standard holes in the cross section of the extrusion. We highly recommend tapping these holes and then using threadlock to retain the bolts. So far we’ve only had to use a single bolt since we haven’t experienced very large forces The...

    REVolution 15x20 Tooth Sprocket

    REVolution 15x20 Tooth Sprocket By Tycho

    Task: Power to the REVolution

    This is our REV0lution 20 tooth sprocket for #25 chain. This took a lot of trial and error to get right, because it was the component most sensitive to our print settings. We had to inset the tooth profile quite a bit because any extra material created by perimeter settings would cause the gaps between teeth to be too small for the chain to fully engage,...

    REVolution Pillow Block

    REVolution Pillow Block By Tycho

    Task: Power to the REVolution

    This is a standard pillow block. We had to add adhesion pads to the ends because the nylon would curl away from the print bed. But these are easily cut off with a hobby knife.

    REVolution Pulley

    REVolution Pulley By Tycho

    Task:Build an Army Worthy of Mordor

    This GT2 pulley has rounded teeth that engage nicely. GT2 pulleys and timing belts are the most common in use with 3D printers - but those are usually of the 2mm pitch variety. We didn’t think our printer would be able achieve the fine detail accuracy needed to print at that size, so we went for the 5mm pitch belts. On our printer we can take this...

    Gripper v4, Octopuckers

    Gripper v4, Octopuckers By Tycho and Abhi

    Task: Design a new piece for intake

    Version 2 of our gripper arms worked much better than our original. Due to their silicone material and trianglular shape, we definitely had more control over the glyphs than our one degree of freedom grabber arms. However, we still had issues we needed to address. When glyphs were taken in, since the silicone surface did not have much mobility and compressibility, glyphs would often fall. Due to slight...

    Grabber Arms v3

    Grabber Arms v3 By Abhi and Karina

    Task:Develop a More Efficient System

    At the Oklahoma qualifier, we saw numerous teams with similar systems to that of ours. However, since we had the mobilized gripper arms to stack with auto alignment, we were able to collect glyphs easier. In spite of that, after observing other teams in action, we realized our current gripper method had the issue of not being ready by the time we got back to the cryptobox. This is...

    Machine Vision Goals – Part 1 By Tycho

    We’ve been using machine vision for a couple of years now and have a plan to use it in Relic Rescue for a number of things. I mostly haven’t gotten to it because college application deadlines have a higher priority for me this year.

    V2 Hexifier and Parts By Tycho and Abhi

    Task: Creating the Parts for V2

    Today we continued our work on the second grippers. We talked about this in another post, but the gist is that we iterated through various materials to find something that would securely grip the block, without damaging it. At the beginning, that got rid of most of our options, but we tested various sprays, materials, and pressures to find the right material. The baking pan liner was...

    Task: Test Materials for V2 Gripper

    Though our current gripper is working sufficiently, there are some issues we would like to improve in our second version. The mounting system is unstable and easily comes out of alignment because the rev rail keeps bending. Another issue we've encountered is the cervo pulling the grippers so that they begin to cave inwards, releasing any blocks being held at the bottom. By far the biggest problem is...

    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...

    The RV exterior


    We have finished the majority of the renovation of the Dallas City of Learning Lab. We've finished rebuilding the roof, going throught the plumbing (including the suspiciously secretive water tank), and also replacing the entirety of the flooring.

    Mobile Learning Lab Part 3 - Flooring

    Mobile Learning Lab Part 3 - Flooring By Evan, Max, Tycho, Dylan, Ethan, Caitlin, Darshan, and Austin

    Carpet ripping is not fun. The carpet is tacked down with so many staples that is is not easy to remove. It tends to rip around the stables leaving nubs of fibers and then we have to attack the stables with pliers and staple pullers. Getting it out from under the edges of walls and the slide out is really hard. And we've...

    Mobile Learning Lab Part 2 - Roof

    Mobile Learning Lab Part 2 - Roof By Tycho, Max, Matthew, and Austin

    Task: Clean the roof of the RV

    We'd noticed that the roof was very grimey looking from the small strip you could see at the top of the side walls, but we hadn't been up there to look at it. Finally climbing the ladder we confirmed it. The roof is a very dark brown. We believe it is simply dirt that has caked into...

    Mobile Learning Lab Part 1 - Demolition By Evan, Max, Tycho, and Austin

    Task: Redo the inside of the recreational vehicle

    Mr.Virani recently aquired an RV so it could be used as a mobile learning center for the Dallas City of Learning this summer. To convert it from someplace you might live on a long road trip to somewhere you could teach science and technology to children means stripping out carpeting, removing walls, and laying down...

    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...

    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...

    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

    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

    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...

    General Blog Improvements

    General Blog Improvements By Caitlin

    Task: Make blog more accessible and simpler to write for

    In a rough order, here are the things I've worked on in the blog over the past month or so:

    • Add a readable nav-bar and fix header text color
    • Add About page structure for new members to fill in
    • Resize a bunch of images to fit the 600 px width, and a couple that were too tall
    • Create tag-specific post pages
    • Make these tag pages Case-Insensitive so posters could tag "Design"...

    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...

    General Improvements

    General Improvements By Jayesh, Omar, Darshan, Max, Caitlin

    Task: Perfect and improve multiple of our main characteristics of our robot

    Iron Reign held its first Christmas break parade today and we decided to focus our time on making multiple small improvements, rather than adding one big part on our robot. Omar, Darshan, and I spent our time on rewiring and fixing our side motors. We found that one side was greatly lagging behind the other, so we tested to see which motor was failing, and rewiring the system fixed our driving system....

    Slide Trigger

    Slide Trigger By Max

    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...

    Design and prototype a churro latch mechanism

    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

    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...
