Finally it's here,  I've made the CAD files for Dogbot publicly accessible! 

You can access the CAD via the link:  https://a360.co/2YuGwaC

There are some caveats with the design as it stands. Though the design will work with 3D printed planet gears, the forces are on the edge of what they can handle and they do break fairly easily.   If the robot is to last any length of time they really need to be machined from something like 7075 aluminium.  The bearings do tend to loosen up as well, ideally they would be replaced with something with hardened metal surfaces which would last a little longer.

I've not yet published all the design for the motor drivers, and control software.  If there is interest I can publish these as well, though both need further work.

I am not too happy with the motor controllers at the moment, I am looking at a redesign. It maybe better to use something like the o-drive https://odriverobotics.com/  for the moment.

I don't want to be too self-promoting, but you may find something like my moteus controller to be a decent fit, depending upon your exact power requirements: https://hackaday.io/project/167845-mjbots-quad/log/175772-production-moteus-controllers

Hi Charles: We are trying to print one here to repurpose with A Thermal camera for CoronaVirus. I will start printed soon, but would be great if you can publish the motor drives and control software.!
