    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 the cliff hanger to move our center of gravity forwards, and then retract to bring it back.

    Reflections

    We were able to make the board speed up by tilting the cliff-hanger out and extending it, but we couldn't control it enough to completely stop it or keep it steady. We believe that the robot frame isn't completely rigid and is torquing at the center, making the robot unbalanced left/right. Since it's only slightly off balance we can't really adjust it by hand. It seems doomed to drive in circles forever. We tried to turn the robot to a correct alignment by driving with the main treads a little, but the change in center of gravity was too dramatic. The robot quickly veered into Evan, who was sitting nearby.

    Hoverboards and PID

    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 and then getting creative with the controls to speed it up. We found that we could effectively rocket it forward by extending and angling the cliff climber while flipping the block dispenser forward at the same time. While it was easy to send the robot forward, there was little we could do to recover outside of just pushing it back by hand. This created a game of hot potato as we passed the robot around from person to person, but was ended rather abruptly when it careened into the table.

    If we're going to get our autonomous functional for UIL then we need to fix our PID. We used the parts of the current autonomous demo to check the straight line gyro drive, and went from barely correcting, to crazy oscillations, to a good level in between. This took a decent amount of tweaking for K-proportional, and when we felt we were straddling the line between too much and too little correction we messed around with K-Derivative to be better prepared. After the initial gyro guided line the robot is programmed to do a 45 degree turn towards the beacon, and then fine tune its angle using color blob. The color blob detection seemed to track the selected color accurately, outlining the area in neon green, but for some reason didn't turn to aim at it. If anything it turned away from the beacon. We found a mistake in our error calculation, where leftover error wasn't properly cleared before the guided turn, that we believe caused at least some of the odd turning behavior.

    Inspire Award

    Inspire Award By Tycho, Jayesh, Caitlin, Omar, Max, Darshan, Evan, Ethan, Janavi, and Charlotte

    1st Place at North Texas Regional Championship

    Iron Reign members left to right are Ethan Helfman (Build, Communications), Janavi Chada (Programming, Communications), Tycho Virani (Programming Lead, Main Driver), Jayesh Sharma (Business Lead, Build, Communications), Darshan Patel (Build), Caitlin Rogers (Communications Lead, Logistics, Business) and Charlotte Leakey (Programming, Logistics), with Evan Daane (from BTW, Build, Photography) in repose. Not shown: Max Virani (Design Lead, Programming), Omar Ramirez (Build Lead) and Rohit Shankar (Programming).

    Wow, we did it. I mean, we were going for it, but wow - we did it! Out of 118 teams competing in our region, we got 1st Place Inspire (Top Award) at our regional championship! We finally earned the coveted Inspire Banner. We've been building toward this for 7 years! Ever since we started as an FLL team.

    Our total awards included Inspire 1st, Finalist Alliance 2nd, Motivate 2nd, Connect 3rd, Innovate 3rd.

    Not going to Disney World yet

    We are now qualified for the Texas State UIL Robotics Championship and the 12 State South Super Regionals. And we are preparing with the goal of making it to the World Championship. We have an extended season and while some of us have been to super regionals before, this is the first time the whole team gets to go. Our coffers are empty, we need a whole new round of fundraising to keep up the progress for the extended season. We need your help! Please consider contributing to support our extended season and help us represent North Texas at Supers.

    In case you don't know how the game works, it's broken into a 30 second autonomous phase followed by a 2 minute driver controlled period. Two alliances of two robots each compete in each match. Here is our division winning match with alliance mates Technibots. Autonomous:

    Task: Create a video outlining Iron Reign's outreach

    We have had a lot of interest garnered towards the STEM outreach the team has committed to. When we found that FTC encouraged the creation of a video outlining the STEM outreach we had done, we saw it as an opportunity to show others a general overview of our activities. With Max's excellent voiceover, we made a video talking about how long the team's been at it, the various STEM expos/events we do, and how the problem of summer learning loss lead us to making the Mobile Tech Xperience.

    Reflections

    Making a connection and advancing our community has always been a priority with our team. This video helps give us a short summary to show parents and children the benefit of commiting to the STEM field, specifically in robotics. We started because of two parents who decided to start a robotics team with some energetic middle school 7 years back, and look at us now. We want to tell these interested parents and kids about how their dedication can create something special, and we're doing that by using ourselves and FIRST as examples. We plan to spread this video to those looking to get into FIRST, or even those simply interested in what our team does besides build complicated contraptions.

    Editing the Reveal Video

    Editing the Reveal Video By Evan and Omar

    One man's harrowing journey through copyright free music lists

    The Robot Reveal video is underway. With most of the filming done, the sky grows dark and the day ends. A night time of editing sets in for the poor miscreant who volunteered for the task. Huddled in the corner with a raw fish and his precious computer, the boy opens premiere pro to begin. All is right with the world. The five hour long dramatic saga of trying to figure out the dang code to his Adobe account is through and the password has been changed. He knew he never should have let his family use his student status for a discount. But it's over and he's decided to leave it in his past. Time to edit...

    So the editing for the Robot Reveal video has begun and so far it's gone fine. I had an easy time getting it all in and except one crash(everything was recovered) it's been good. There won't be too much extreme editing to do. Nothing mind bending. Mostly cutting and arranging. The big problem now is finding a song to use that fits the video. I'm having trouble finding something pleasant sounding, fitting, un-copyrighted, and that lines up with the length of the video. I've been listening to a ridiculous amount of un-copyrighted music. An insane amount. It's not copyrighted for a reason. No man or woman or animal or object should have to endure this. The un-copyrighted playlists should be used as an enhanced interrogation technique and then banned by the UN for being a violation of basic human rights. Its all a bunch of extremely similar songs that should either be in the background of a shirtless guys vlog or the basis for an art students performance piece. A few outliers are some EDM and elevator music and I don't know which one makes me want to pour hot wax into my ear holes more. I'm listening to a song right as I'm writing this. I think it's the background music for the most generic cooking channel on YouTube ever. One way or another I'm going to get this done. Maybe I've made a few hyperboles throughout the post but the robot reveal will be finished. I've saved all the music I think could work into a playlist that I'll let everyone give a listen to at tomorrow's meeting. Now I must return to my hell.
