While child-sized humanoid robots like the Unitree R1 have come down in price, not everybody has a spare $6,000 to throw ...

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.

The robot is based on a two-wheeled design with tank-style steering. Controlled by an Arduino Uno, the robot uses a Slamtec RPLIDAR sensor to help map out its surroundings.

By harnessing the power of 3D printing, servo motors, and Arduino programming, you’ll create a robotic arm that responds to your commands through a sophisticated software interface, allowing for ...

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.
