What It Does

Our bot efficiently scores points on the custom game field at MakerHacks. It effectively crosses sides during autonomous and prepares to carry 3 blocks at a time up the ramp, to the scoring area. It uses 4 individual continuous motors and two servos to have an arm for scoring. Our strategy utilized the maximum number of cubes that could be held at one time, 3 while maximizing points during the Auton period.

How We Built It

We used an esp32, 4 continuous TT motors, and 2 servo motors for hardware. The 4 continuous TT motors made up the drive train, while the two servos were used to maximize torque and lift the arm. We didn't have access to 3D printing earlier in the hackathon, so we innovated and built the robot from cardboard pizza boxes. We were able to 3D print an arm and use it to score points. For software, we used C++ to implement a WebSocket Wireless AP server. This ensured minimal latency when communicating with the bot during TeleOp periods. In the end, this system proved to be useful.

Challenges, Accomplishments, and Things Learned

This was our first hardware robotics hackathon, so we had to iterate our strategy a lot. Our 3D prints had issues the first time around, so we innovated to use a combination of cardboard and plastic. However, in this process, we learned a great deal about being resourceful and efficiently building algorithms. In the future, we hope to plan better and improve the structural integrity of the bot.
