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.

His latest project is a sophisticated line follower. You’ve probably seen “bang-bang” line followers that just use a photocell to turn the robot one way or the other.

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.
