Pi-0.5 can post-train to grab a pen, but legs-balance coordination is the hard part

Darpinian clarifies the hard part isn't post-training Pi-0.5 to pick up a pen — that's easy. Pi-0.5 can't balance a humanoid on its legs, so a separate system controls the legs, making leg-arm coordination to bring the grippers to the floor the real challenge.
