Raspberry Pi Rover

thingiverse

The objective was to create a compact, continuous-rotation servo-powered rover featuring two wheels that can support a Raspberry Pi. This involved modifying inexpensive 9g servos to enable constant rotation on both main wheels while incorporating a passive swiveling front wheel. Servo modification included drilling the output shaft to prevent potentiometer rotation (set at center position, secured with glue). For enhanced traction, rubber O-rings from hardware store plumbing were added to big wheels. The rover has been driven using an RC receiver; Raspberry Pi integration is pending. OpenSCAD source includes STL for the entire assembly, requiring separate export of individual components (big wheels, front wheel, base, and suspension). A broken RC helicopter supplied the 5mm diameter ball bearings used for front-wheel swiveling/rotation axis.
