This is a detailed video review of the Morph 4 wood model. It shows each joint in detail, and gives an overview of the mid-morph lock that I'm proposing. This video is intended as input to Graham Butler, who is starting on the frame design for Morph 4. The wood model shows the location of all the joints, and demonstrates how it all moves. The actual frame design will keep this same geometry. Of course, all the rest of the decisions still need to be figured out -- the mechanics of the lift system, the foot rests, the seat adjust, the mid-morph lock, and the frame design and materials. Over to you, Graham. We have another online design session on Wednesday, January 20, 2010.
