FIRST Tech Challenge: Design a robot constrained within an 18in x 18in x 18in space with autonomous and human control that can efficiently collect different-shaped objects and deposit them into an elevated depot. Robot must also be able to lift itself up. Points are scored based on speed and accuracy of the tasks. We competed at the 2019 FTC World Championships in Detroit, MI. 

​

This was my first engineering experience and I learned a lot about working in a collaborative setting and blueprinting thoroughly before executing on plans. We proceeded with several design iterations, including an Auto-Lock Lift Mechanism. The hook allows the lander support to slide in, but not slide out. As the robot pushes the lifter up and the hook touches the lander support, the rubber bands are stretched as the hooks get inside the lander supports. We also implemented an intake mechanism with passive sorting to automatically separate spheres and cubes.

 

Arduino was used to implement a gyroscope and accelerometer both into our robot, all in a tiny chip. Before we can use it with REV, we need to adapt its breakout board into the pins of a REV cable. We soldered the pins across the REV hub cable and the breakout board, then safely sealed them with heat shrink tubing. We then inserted it into the custom 3D printed housing.

​

In the autonomous portion of the competition, the robot uses PID precisely position itself to pick up the game elements. A custom webcam mount was also designed for image recognition.
