flywheel - autonomous robot

 

This autonomous bot was my final project for Introduction to Mechatronics. The bot was built in the final two weeks of the course in groups of four engineers. In total, thirty-two Teensy LC powered bots competed head to head in an elimination bracket. Our bot placed 3rd out of 32 teams of graduate students.

THE TASK

In 2 mins 10s, autonomously navigate the game board to a loading location, load ammunition (yellow nerf balls), locate your opponent’s towers, and shoot them down. The team with the most towers knocked down wins.
