Raspberry Pi + Java R2D2 Robot – Part 1


This project was born as a Coronavirus project for my kids (you know how difficult could be to have your kids all day at home… oh school: please come back, we forgive you!)

On this post we cover the initial steps, including the full platform/chassis running, commanded by a Raspberry Pi and some Java code.

On this video we can see the chassis running:

 

The body of the R2D2 will be a 12″ cardboard tube from Home Depot. The chassis aluminum flat bars are also from HD:

We are using two separate battery packs: one for the raspberry and a second one (more amps and 12V) for the motors and the L298n motor driver:2020-04-19 13.02.19
