Really liking this design
Because this is a 3-position piston, does that mean that when the PTO is engaged, the robot won't be able to move around?
Also, what is the PTO capable of doing? I'm not sure if a 5:1 ratio might be enough to, say lift the robot's weight off the ground.
Finally, where can I find the ballshifter PTO? For the dog PTO I did, I had to rip the hub off of a .step file from a wcp gearbox.
