Romi and Raspberry Pi robot

Forum user DrGFreeman has been busy making robots. I wrote earlier about his Custom Mini Sumo robot; now here is his Romi Chassis and Raspberry Pi robot. It solves mazes using a webcam to do line tracking and intersection identification. This robot is a great example of how a variety of Pololu robot parts can combine into an attractive and functional robot. A black Romi chassis kit provides the base for the robot, to which DrGFreeman added a encoder pair kit and ball caster kit. An A-Star 32U4 Robot Controller SV with Raspberry Pi Bridge drives the motors and monitors four Sharp GP2Y0A60SZLF analog distance sensors and the Romi encoders. The robot controller and the Raspberry Pi communicate via I²C and are elevated above the chassis on a narrow Pololu RP5/Rover 5 expansion plate.

DrGFreeman is also working on a mast for three VL53L0X time-of-flight distance sensor carriers that he plans to add for simultaneous localization and mapping (SLAM).

For more videos, pictures, and details, see the forum thread. The robot’s Raspberry Pi (Python) and Arduino code is available on GitHub.
