Abstract:
A controllable ratcheting apparatus having robotic modules rigidly attached for operation near a mechanical singularity includes a plurality of modular joints and ratcheting means. Each one of the modular joints is capable of locking and unlocking to effect performance of a ratcheting motion as the ratcheting apparatus approaches a mechanical singularity. A plurality of links is connected to the modular joints in such a way as to permit movement of the links while under large external forces as the joint approaches a point of mechanical singularity. A control system directs movement of the modular joints and links.
