The robot’s hardware was constructed in accordance with the Open Robotic Platform (ORP) rules. This included two DC motors, an UNO R4 Minima, a Bluetooth module, and an SD card.

The build relies on the classic Arduino Uno microcontroller, which talks to a HC-SR04 ultrasonic sensor module and two infrared sensors in order to track a human target and follow it around.
