In this project, the team used a Raspberry Pi Zero to control a robot to automatically search a ring for another object and push it out. It did so using an ultrasonic sensor to detect the object and a color sensor to ensure that the robot, itself, stayed in the ring. It was housed in a 3D printed enclosure to keep it within the weight limit of 500 grams. It included a PCB battery indicator that would illuminate up to 10 LEDs to represent the health of the batteries used to power the robot. The robot also has the option for manual control using a Bluetooth connection to a PlayStation 4 controller.
