Last week I decided to replace our older Model 1B Pi’s with a spanking new ZeroW + a PiZ moto Driver board. This board was purchased last year from Mark Cantrell (ASTRO Designs) who runs the micro-pi-noon robots @ Cotswold CAMJAM. Here it is on a tracked robot chassis. This gives us more room, and flexibility + onboard wifi + Bluetooth.
I’ve been planning to try out the driver (PiZ-Moto) for a while, and it provides a method to power both the pi + motors using a 7.2 V LiPo battery. It’s fully compatible with the CAMJAM Kit as well! And Mark even handed over some code to try it out. It really is a neat driver.
We added it to our design this week to test it out with a Wii controller. The extra power now gives our robot plenty of grunt, but the robot now proves a big to jumpy to control accurately! Here’s a video of it in action on a test golf track.
