    The kinematics of a new spherical parallel manipulator is described. The manipulator consists of a base and a platform which are linked by a serial URC-chain (universal-revolute-cylindrical). The pure spherical behavior of this mechanism is obtained by imposing some mounting conditions. The author derives at first the mounting conditions, and then performs a position analysis and a singularity analysis.
