报告内容摘要：
High-performance parallel robots are required for fast and flexible pick-and-place operations in the food and packaging industry. In this talk, the development work of a parallel robot of the Schoenflies motion is presented. The robot, called Ragnar, is aimed to generate a workspace of desired shape, namely, a nearly superellipsoidal workspace, which is close to the applicable work volume and suited best for pick-and-place operations. The kinematics of the robot is developed, with the workspace being analyzed and optimized.  A method of stiffness modeling by means of Castigliano’s Theorem is formulated. Using the new method, the stiffness of the robot is analyzed. A novel compound platform is also presented, which improves the performance of the robot by implementation of full rotations of the end-effector.
