Spherical Quadruped Arduino Robot. 9 Comments . by: Orlando Hoilett. May 21, 2020. Title: ... [Greg06] even included an ultrasonic distance sensor for the obstacle avoidance mechanism.

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.

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 DIY robot vacuum cleaner is equipped with what seems to be an array of ultrasonic sensors for navigation and is powered by an Arduino Mega-development board, attached to a HC-05 Bluetooth ...

I have used an Arduino Uno to monitor two ultrasonic sensors in the base of the Dalek and send the results over the USB serial interface to a Raspberry Pi which then plays an MP3 clip.
