I loved the Zerobot Pro Tank so much that i've printed one.
Build log
Received the motors, so built everything up.

Setup
Planned software setup ;
- https://www.ros.org/
- https://github.com/alansrobotlab/rospberrypi - Everything you need to set up ROS Melodic on the Raspberry Pi Zero / W (gives errors on latest stretch images)
- https://github.com/SamSpaulding/ros_raspberry_pi_zero - seems to compile most of it from source, viable option?
Something for sending 4 PWM signals to the DRV8833 (arduino pro mini? teensy? bit overkill .. )
Or connect the DRV8833 to Pi directly?
Beyond camera and 6dof no other sensors for now. Some kind of external brain ros instance aswell? LXC?
