    Robot Video Analysis

    Robot Video Analysis By Charlotte

    Task: Determine the acceleration and max velocity experimentally

    To find the acceleration and maximum velocity of our robot we decided to use a method we have learned in our physics class at school: video analysis with Logger Pro. The procedure is like so: Take a video of the robot head on with a still camera. In the video, in the same frame of movement as the robot, hold a known measuring device (ruler/meter stick). Insert the...

    Importance of Documentation

    Importance of Documentation By Abhi and Tycho

    Task: Explain commits

    As explained in a previous post, we were having many issues with git commits and fixing our errors in it. After a lot of the merging conflicts, we had to fix all the commits without exactly knowing what was being changed in the code. Part of the reason this was so hard was our lack of good naming conventions. Though we always try to make a title and good...

    The Cost of Mistakes

    The Cost of Mistakes By Abhi

    Task: Analyze Failures

    Two words describe the picture above: "Oh dear". The wires shown above are connected to our jewel thief on the bottom of our robot. The reason the wires are so shredded and torn is because the chain on our grippers would rub against the wires when the lift was in the lower position. However, it was not always like this.

    Motor Constants and Future Plans

    Motor Constants and Future Plans By Ethan

    Task: Find constants for the motors for future calculations

    In order to better predict how our robot will work, we first need to find a few constants to do calculations. Luckily, our school has an engineering class, so many of us have the skillset to do these calculations.

    The base data we needed was:

    NeverRest 40s:
    &tab;160 rpm\16.755 rad/sec
    &tab;369 oz-in\2.6057 Nm

    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...

    Designing the Tent

    Designing the Tent By Janavi and Kenna

    Task:

    So, its Supers time again! And that means its time to design our tents and pick a theme for ourselves. Last year, when Iron Reign went to Supers for the first time, we got to see all of the other teams' displays; before, we had only been to regional level competitions and weren't ready for the displays at Supers. We saw the coolest tents and got some really cool trinkets. For example, one...

    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...

    Task: Make team informational posters for South Super Regionals

    Last year, we didn't spend that much time on the poster/aesthetic side of things for Supers, and we ended up getting the Judges' Award. While we can't really prove a cause-and-effect relationship between the two, we want to improve in all aspects so we don't repeat last years performance. So, this year, we're going to try to convey more information to the judges so that we can bolster...

    Polycarb Deformation

    Polycarb Deformation By Ethan

    Task: Find a constant for polycarb deformation

    Recently, we've been having an issue with our gripper in that the shielding for the sides of the intake have been bending torsionally, so that they deform and interfere with our glyph take-up. So, we created a lab to find the torque required to cause this deformation.

    We cut a length of polycarb with a similar width but different length to test this (thickness...

    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...

    Oklahoma 2017 Post-Mortem By Ethan, Evan, Tycho, Austin, Janavi, Kenna, Abhi, Charlotte, and Karina

    Task: Recap what went right and wrong in Oklahoma

    Even though we did very well in the Oklahoma qualifier, we still encountered several problems, that if not addressed, could lower our chances of getting to Super-Regionals. So, we had a team discussion on what to do differently in the next tournament, and what to keep constant.

    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...

    Task:

    A few weeks leaving for our Oklahoma competition we assembled a large garage tent upon the pool deck and moved our field inside the tent to shield it from the weather. The night before the competition we moved in a projector so we could project see the code on the wall and left it there when we went to Oklahoma. We were very surprised...

    The basters are here and in full swing. We spent a late night putting together the two intake columns. They were attached to a backing by previously, allowing to finish it by attaching the final servo and tieing it to the two columns. Since the new intake needed new code, we whipped up some code to allow us to have control. Upon doing this he realized...

    Task: Learn how to Assemble parts in Creo Parametric

    In addition to making parts to print in Creo, it is sometimes useful to combine multiple parts to make a model. For example, we can make a robot model by assembling parts in Creo. We have conducted a video on how to do so.

    For this tutorial, we first created two simple parts...

    Gripper Part 2

    Gripper Part 2 By Evan

    Update:

    The task today was simple. We replicated the prior work with the first gripper, as stated in the prior post, so we can begin connecting them. The biggest problem was finding all the parts to make it. We are hoping we can connect and mount them in the next couple days so it will be ready for the qualifier in Oklahoma. The improvement over last post was the addition of the rubber gripping material, as...

    Driving Struggles

    Driving Struggles By Abhi

    Task: Drive the Robot

    Today we tried to drive the robot on the practice field for the first time since the qualifier last Saturday. However, we couldn't get in very much quality drive practice because the robot kept breaking down. We decided to dig a bit deeper and found some issues.

    As seen above, the first thing that was wrong was that the lift was tilted. Due to the cantilever orientation of the...

    Greenhill FTC Qualifier By Ethan, Evan, Tycho, Charlotte, Austin, Abhi, Tycho, Karina, and Kenna

    Task: Compete at our first FTC qualifier

    So, we were absolute failures. There's no way to get around that. We got 14th place out of 14, and our presentation flopped. But, its not the end of the world, even if it may feel like it. We have another qualifier in Oklahome in one week, and we need to analyze what we did wrong...

    Relic Recovery Strategy Part 1

    Relic Recovery Strategy Part 1 By Austin

    Task: Determine building strategy for Relic Recovery

    Any well-versed team understands that, depending on the competition for the year, a robot will either be modified to compete or be built from the ground up. In any case, however, a robot often starts at its chassis, and teams have multiple companies that provide solutions to the common robot chassis’ needs and specifications. To name a few: AndyMark® has its standard kits that include all the...

    Designing the Jewel Thief By Evan

    Task: Design a part to remove the jewel

    The jewel thief, the mechanism for knocking off one of the jewels, was going to be one of the tougher parts of our bot to integrate, based on the chassis we began with. But, with a little engineering and some long thought, we came up with a few ways to implement it. First, we began with a side mount, and it was alright...

    Gripper Construction

    Gripper Construction By Tycho

    Task: Making the Gripper

    Standard parts were used to create the backbone. Then, we bent some tetrix parts to connect the backbone to the servos. We used continuous rotation cervos to solve the issue mentioned earlier. This was a fairly easy build but we still have a ways to go before V2 is completed.

    This gripper will be far superior to our prior designs in that it will be...

    Wheel Protector Correction

    Wheel Protector Correction By Abhi

    Problem: Wheel Guard Innacuracy

    Refering back to the design of the wheel guard, we decided it was time to actually mount it on the robot. At first, it seemed like the part was perfect for the robot since it fit just snug with the screws on the wheel. However, upon mounting, we discovered the following:

    Turns out that the part is acutely shorter than the real height of wheel relative to the horizontal axis superimposed upon the vertical plane. As a...

    Stopping Glyph Damage

    Stopping Glyph Damage By Abhi

    Task: Stop Destroying Glyphs

    Since damaging field elements is a huge no-no, we needed to fix this, we decided to create a 3-D part to protect the glyphs from our wheels

    Model:

    During the first attempt, I had just self taught Creo hours prior to construction. As a result, I was not very precise nor efficient in my design. Nevertheless, we recognized that there were some basic shapes we could use for construction such as a semicircle for the bottom half and two rectangles on the...

    Because our robot at this point has merely become a collage of prototypes that we compete with, there are often subtle improvements that need to be made. Starting with the wheelbase, Abhi has written a blog about the shields we printed to protect the glyphs from the gnashing bolts of our mechanum wheels, and we also tensioned all our set screws and motor mounts to make sure that our...

    V2 Hexifier and Parts

    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...

    Designing the Grabber

    Designing the Grabber By Austin

    Task: Work on the grabbers more

    With our single degree of freedom lift fastened to the robot we focused on the appendage that would grip to within an inch of its life any glyph we fed it. We initially toyed with simple tetrix channels to form a make shift rail that would hold axels for pivoting points, however we found tetrix to be a bit too cumbersome and decided to use rev...

    The grabber has been evolving. A column made of a turkey baster and a wooden dowel attached to servo has come into fruition. The first drawings and designs are coming along, and some 3D printed parts have been thought up to allow the square dowel to become a hexagon. An adapter of sorts. The grabber and lift have been outfitted with a...

    Testing Materials By Austin, Evan, and and Tycho

    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...

    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...

    Task: Figure out slide mechanism

    After determining that the treaded channel was much too buggy to perfect with the time we had, we shifted attention to other scoring systems like grabbers, however before finding the right grabber we decided we needed to get the track for it completed first. We’ve had experience in the past with all sorts of rails from Tetrix kits that convert their standard channels into lifts, to the newer...

    In an attempt to get a working lift system before the coaches meeting we will be presenting at, a linear slide has been attached to the robot, along with a pair of grabbing arms. They work surprisingly well and aren’t as complicated as my idea. Plus the importance of speed has really taken hold on me this year. We need to be as fast...

    Task: Work on designs for the intake system

    Over the past couple of days we’ve experimented with a horizontally mounted track system that we had hoped would serve to move blocks through the entire length of the robot and into the crypto box. Immediately we noticed a few issues, the primary one being that the tread was static in terms of mounting and therefore wasn’t accepting of blocks when feed at an odd...

    The sun came out and it was back to the field. We got started right away, both of us building our designs. Since the cryptoboxes were wider than the 18 inch sizing cube, we started by designing a fold out for the conveyor belt. This was entirely proof of concept, purely to see if it was at all aplicable in the game...

    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...

    Turn Up! at Frontiers of Flight with DCOL By Janavi, Darshan, Jayesh, Caitlin, Max, Tycho, Omar, and Austin

    Inspiring 1,000 People to Turn Up with STEM

    Written by Janavi Chadha

    The Dallas City of Learning Organization held a Turn Up event at the Frontiers of Flight Museum, where we staffed the Mobile XPerience (MXP) complete with laptops, 3D printers, and LEGO SumoBots. Outside the vehicle, Caitlin and I taught kids how to create 3D models...

    Hoverboards and PID

    Hoverboards and PID By Caitlin, Omar, Darshan, Tycho, and Max

    Task: Continue with the Hoverboard and tweak PID

    After the long weekend last week, today was a reasonably relaxed practice. We decided that we could work on anything, as long we stayed focused. The two main foci were the -Robot on a Hoverboard- and fine tuning our PID for autonomous.

    Reflections

    We experimented with balancing the robot more evenly on the hoverboard to keep it on a straight path...

    Day 2 of iMake

    Day 2 of iMake By Caitlin, Max, Tycho, and Omar

    Task: Continue presenting at iMake

    Day 1 was a huge success, and we carried that over into the Sunday presentations too. There were a lot of common questions we noticed from Saturday, including levels of robotics competitions and the LEGO EV3 system, and we were able to answer these with more clarity after hearing them so often. A few papers were set up on our table outlining the various FIRST competition...

    Robot On a Hoverboard - Try 1

    Robot On a Hoverboard - Try 1 By Caitlin, Max, Tycho, Darshan, Omar, Evan, Ethan, and Jayesh

    Task: Try to drive the hoverboard with the competition bot

    In the middle of Saturday's event we decided it would be a GREAT idea to put the competiton robot on the hoverboard and try to drive it around. Theoretically if we got it centered correctly it could only drive forward and backwards. We could extend...

    Presentation Runthrough

    Presentation Runthrough By Caitlin, Max, Tycho, Darshan, Jayesh, Omar, Alisa, Ethan, and Evan

    Task: Go through presentation with Mr. Gilkes

    Our mentor Mr. Gilkes was kind enough to listen to us do a rough presentation run-through at practice. We hadn't looked at the presentation since the competition 2 weeks ago, and it was pretty obvious we were under-practiced. We swiped through the slides before starting to get our bearings.

    Reflections

    We started by making sure everyone knew their cues,...

    Post Competition Goals

    Post Competition Goals By Jayesh, Omar, Darshan, Max, Tycho, Caitlin, Ethan, Evan, Dylan, Alisa, and Trace

    Task: Discuss future goals and fixes needed to succeed at regionals and beyond

    In the week following the competition, a Google document was made to discuss sections of building the team can improve on before the regional tournament. There was an outline made where every team member applied to certain sections that they felt needed to be improved upon. The different sections included robot chassis, the presentation, and game strategy. Members voted on item...

    Nolan Qualifier

    Nolan Qualifier By Ethan, Caitlin, Jayesh, Darshan, Max, Tycho, Evan, Alisa, Trace, and Dylan

    Task: To review our last tournament

    Beginnings

    Due to the team taking a bus with Imperial Robotics, we arrived to the competition a little late. However, due to an organizer running late, the competition itself was delayed, so we weren't significantly affected. Like last time, we had trouble finding a power outlet that we could set up our battery box near, but it turned out there were a couple nearby. We were once again set up...

    Competition Post-Mortem

    Competition Post-Mortem By Caitlin, Jayesh, Darshan, Max, Tycho, Evan, Ethan, Alisa, Trace, and Dylan

    Task: Analyze our successes and failures in the previous competition

    After a rocky start and finish to our first qualifier yesterday we took today to have fun as a team and look at how we could improve for our next chance.

    Reflections

    Most of our -Need To Do's- are related to becoming more confident with the various tasks that we'll be doing in the...

    I Still Won on the Inside… 2016 FTC Qualifier at Wylie

    I Still Won on the Inside… 2016 FTC Qualifier at Wylie By Jayesh, Omar, Darshan, Max, Tycho, Evan, Ethan, Alisa, Caitlin, Trace, and Dylan

    Starting out

    Just as in previous years, Iron Reign set off about half an hour late. We REALLY need to get everything not directly on the robot printed, boxed up, and loaded the night before - at the latest. Now that we have 11 members, we needed another person to help carpool, and Jayesh’s dad was thankfully willing to help. (note from omar: we definitely did not...

    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...

    Intro to Gyros

    Intro to Gyros By Caitlin, Tycho, Max, Omar, and Jayesh and Darshan

    Task: Share what we've learned about motion sensing

    On July 11th we gave a talk for a classroom full of adult members of the Dallas Personal Robotics Group (DPRG) where we shared what we've learned and are still learning about motion sensors, particularly gyros. The talk took place at the Dallas Makerspace. Our thanks to DPRG, Steve and Doug for hosting us and recording and editing the video. The...
