I also modified the wheel modules to make the actuation more robust and moved the chains to the outside tube to make maintenance easier.

We are planning on making this version, but we are not going to do the traction wheels because they add a lot of cost (around $400).


I'm not sure what you mean by not having gearboxes, but any drive is going to have some kind of gearbox. This just has the gearboxes integrated into the frame.

That entirely milled out tubing looks like it will bend like a toothpick. Add some more supports in there
