Our week-zero practice event was a success! Five teams from around the area attended, and we all had a productive day of building, testing, and scrimmaging. The teams arrived at our practice field at 8:00, and shared many ideas with each other as we all, at various stages of development, prepared for bag day on Tuesday. Many thanks to Gustavus Adolphus College for providing us with the space for our event as well as a delicious lunch! Thanks to all the teams for coming to work with us and make our practice event a success.
Spent a while working out the algorithm and math for our climber. Since we're using a potentiometer in a linear fasion, it creates a Sin wave, so we had to work with that when writing the code. Here's us solving it for the frequency given the location of the separate arms, and the time each arm is taking to move.
Today, after we finished some of our camera tracking stuff, we programmers had some free time. Since it is imperative that the climber we decided to use(the toothed "hedge-trimmer") has both motors run at exactly the same speed, give or take, we decided to start working on the code for it. The only problem is, as with anything, the programming cannot be tested until the hardware is complete. So, we decided to mock up the potentiometer system that we'll be using to drive the climber, in order to complete the algorithm by the time the device is ready. Here's what it looks like(our mock-up, not the actual thing), the two motor represent the motors driving the separate sides of the climber, and the potentiometers are mounted to them by a coat-hanger that we decimated. Our goal is to make the plastic strips attached to the potentiomenters wave back and forth together.
We got the code working for Arick's climber design, here's a video of us demonstrating it on an electrical board.
