­While advancements in exoskeletons have grown by leaps and bounds in the past decade or so, the majority still provide powered or active assistance, few provide a passive solution. However, many people have difficulty rising from the ground, bed, a chair or other similar surfaces because of knee or leg muscle injuries, aging, obesity, or even simply...

In robotic mechanisms, a parallel manipulator uses multiple actuated parallel linkages to synergistically control the motion of the end-effector. In comparison to the more common serial chain manipulator, parallel manipulators typically offer better end-effector performance in terms of precision, stiffness, velocity, and torque generation. Parallel...

Joint misalignment between a wearable robotic joint and its user can result in detrimental mechanical interference. For small degrees of joint misalignment, this interference can result in fatigue and friction-related user injuries, such as irritant contact dermatitis. Large degrees of joint misalignment can result in more severe injuries such as bruising,...

Currently under development are several advances in robotics technology that allow humans to connect with robotic devices such as exoskeletons and physical rehabilitation machines. Robots are currently in development for use in the Military, Medical, Industrial and Private sectors. However there is a problem facing the human users attempting to couple...
