Others are showing intrest in joining the team as design drawings get passed around. The "cool factor" of this design is contagious.
Ankle design shows limits of motion.
This is my second attempt at getting vertical movement from the foot lift motion, while keeping the foot horizontal. The hatched parts in this image are the ankle links with the foot in the down position.
The actuator could either be in the foot, close to the ankle, or in the body at the top of the leg, and linked to the ankle "tendon" style...
I love this walker idea. Richard is getting pretty fired up about it, so when you get the details worked out send us the drawings and we’ll start making parts. Could we make a scale version? I mean can the electronics be scaled up or down? This is good stuff.
