    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...

    Fixing Faulty Encoder

    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...

    Programming our New Robot

    Programming our New Robot By Tycho, Caitlin, Ethan, and Jayesh

    Task: Program our new mecanum wheel driving platform

    Now that our new robot has been built with a mecanum wheel platform, we can start write our drive code and figure out how to make our robot preform three basic motions: forwards and backwards, side-to-side and to rotate. We decided that, in order to get the best understanding of our robot,...

    Adding Blog Features

    Adding Blog Features By Ethan

    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.

    {% assign eh = 1 %}
    {% assign dc = 1 %}
    {% assign ed = 1 %}
    {% assign or = 1 %}
    {% assign js = 1 %}
    {% assign cr = 1 %}
    {%...

    Sumobot Tips and Tricks

    Sumobot Tips and Tricks By Tycho

    Let's assume you are building a LEGO Mindstorms or Vex IQ based Sumobot, but you want to skip some of the basic mistakes beginners will make. Here are some tips and tricks.

    • Know the rules. It's silly to get disqualified because you didn't pay attention to the rules. Know the size and weight limits. Know the allowed construction materials and techniques. Know the startup behaviors. For example, your robot must not move...

    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"...

    Business Planning

    Business Planning By Alisa

    Task: Making a Business Sponsorship Template

    I worked on making a rough draft of a sponsorship template. This template will be used to email companies to ask for their sponsorship. I have a list of companies that have a high chance of sponsoring us. I found several more to add to the list Evan started last week. I also added sponsorship levels to increase interest for the companies: Diamond, Platinum, Gold, Silver, Copper, Steel, Iron. Different levels through our list imply greater rights and priveleges in...

    Researching Awards

    Researching Awards By Caitlin

    Task: Research and understand the various awards

    We rarely prepare enough for awards, usually hoping the practice before that we've done enough to be in the running. Last year we won the PTC Creo award at one competition, but that was a one time deal. This year we can prepare our journal in such a way to make it easier for judges to find what they're looking for when deciding.

    Reflections

    Out of the 9 awards, 7 are given at every tournament....

    Bumper Shields

    Bumper Shields By Ethan and Evan

    Task: To create bumper shields for the robot.

    We needed to create bumper shields because the debris on the field interfered with the tread. We had a prototype on the left,
    Evan and I cut the bumper shields out of polycarbonate with two made for the front and two for the back. To do this, we were trained how to use a bandsaw. We cut them down so that they will be moveable.

    Reflections

    Evan and I will attach the bumpers,...

    Video Ideas

    Video Ideas By Alisa, Dylan, Ethan

    Task: Watching videos to get ideas for our robot

    Dylan, Ethan, and I decided to watch videos to see what other teams were doing to build and improve their robots during the Circle Meeting outside. We wanted to see if any of the designs were successful so we could learn from them. The videos included Robot in Three Days, RiTD Explained, and Trojan Robotics .

    Reflections

    Every video we watched was ahead of us; we have a...

    Gyro-IMU Case V2

    IMU Case V2 By Tycho

    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.

    You can...

    Arrangement and Rearrangement of Motor Controllers

    Arrangement and Rearrangement of Motor Controllers By Omar, Darshan

    Task: Find better configuration of motor/servo controllers and power distribution module on the robot

    Today, we tried to figure out the best possible way to stick all the motor controllers and the PDM together to minimize the amount of space they take up on the robot. Fitting the finished product into the gap on the back end of our robot would also be a bonus. We had previously thought of one way of doing it: When placed on the robot,...

    Building the Field - Part III

    Building the Field: Part III By Ethan, Trace, Alisa, and Evan

    Task: Building the field for the third week in a row!

    Today, for the third time, we worked on setting up the field. We finished the mountains and the climber setup. We made several mistakes along the way. Firstly, we screwed the mountain climber mounts in wrong, not one or two times, but three times. Then, we realized that the mountains couldn't even fit inside the tent and the wooden boundaries. So, we had to dissasemble it,...

    Building the 2015 Field

    Building the 2015 Field By Evan, Dylan, Alisa, Trace, Ethan

    Task: Cleaning and building the Field

    Today we were charged with the task of building the FTC field. There was one problem. The tent we were setting it up in was in a state of decay. We cleaned out the area to make space while others put together the field. It was changed comletely from when it started. When cleaning we discovered many cool things like cassettes and floppy disks. The mat of the field was a little old but...

    I hate tread inserts

    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...

    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...
