I installed a temporary sound system in R2 and wanted to do another garage drive test. Well, the cheap temporary front caster bearings failed so R2 was not controllable. Just like a little 2 year old he went in circles and refused to go where the controller tried to command him.
So I put him back on the bench and removed the front foot for a complete overhaul of that area. I will need to fabricate a method to hang a caster inside my new oversized foot shell. Will one caster be enough? I need to do a lot of research on what designs work for other builders.
