In this paper, we study the isotropic design of two types of spatial parallel manipulators: a three-degrees-of-freedom manipulator and the Stewart–Gough platform. The isotropic conditions for Jacobian matrices, which relate the input joint velocity and output Cartesian velocity, are determined separately using a pure symbolic method. Thereafter, upon(More)

We report a case of laceration of the deep motor branch of the ulnar nerve at the level of the hook of hamate following a complicated carpal tunnel decompression. Good surgical(More)
