Robot-assisted physical gait therapy is gaining recognition among the rehabilitation engineering community. Several robotic orthoses for the treatment of gait impairments have been developed during the last 2 decades, many of which are designed to provide physical therapy to a single joint of the lower limb; these are reviewed here. The mechanism design and actuation concepts for these single j...

This article gives an overview of the Mechanism Model paradigm. The mechanism model paradigm provides a framework to modeling mechanisms for robotic control. The emphasis is on the unification of mathematical models of kinematics/dynamics, geometric information and control system parameters of a variety of robotic systems (including serial manipulators, wheeled and legged locomotors), with algo...

in this paper, a new kind of gripper is designed. this universal gripper is proposed where different objects should be gripped easily, reliably within rapid succession without any feedback. by adding an annular balloon around the granular bag, a lateral force pushes the main membrane and increases the friction force between the bag and the load. according to the acquired test results reported i...
