    Machine Vision Goals – Part 1

    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. But since we already have experience with color blob tracking in OpenCV and Vuforia tracking, I hope this won’t be too difficult. We have 5 different things we want to try:

    VuMark decode – this is obvious since...

    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 need the baking pan liner to adhere to the large square dowel we chose to be the base for our grippers. In order to do this, we had to design and print a hexifier, as seen below, which makes the dowel's square shape into a hexagon. We also designed and printed square pieces...

    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...

    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...

    Return to Machine Vision

    Return to Machine Vision By Tycho

    Task: Prepare to reintegrate machine vision

    A year and a half ago while the new Android-based platform was still in pre-launch, we were the first team to share a machine vision testbed on the FTC Forums. That color-blog tracker was implemented with OpenCV on Android, but with a different low-level control system and robotics framework. Then we integrated OpenCV into our implementation of ftc_app, which was in turn based on the great...

    Beginning the build for the Cap Ball Trapper

    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,...

    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...

    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.


    Flywheel
    So, while we don't have a functional flywheel as of...

    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...

    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...

    2016-2017 Robot

    2016-2017 Robot By Ethan, Omar, Jayesh, Evan, Tycho, and Max

    Task: To build the robot for the 2016-2017 season

    As much as we love our robot from last season, Geb, we need a robot that is better able to fit the season's challenges. Our needs for this year are:

    • Manuverable and fast
    • Able to play defensively
    • Can support attachments such as an intake system
    For manuverability, we decided to use mecanum wheels.

    The cool thing...

    Task: Add Cool and New Blog Features

    I remember, vaguely, that someone on our team wanted to add a post counter for all the posts people appear in. And, today, I did it out of sheer boredom. And, here it is.

    Mobile Learning Lab Part 4 - Update

    Mobile Learning Lab Part 4 - Update By Ethan, Max, Tycho, Caitlin, Jayesh, Darshan, Austin, Matthew, Evan, Dylan, Omar, and Trace

    Task: Covert a 1998 RV into the Dallas City of Learning Lab

    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...
