Abstract: In this paper, we introduce a task-based method for designing underactuated mechanisms which actuators are linked with the joints via elastic elements. We consider multi-joint mechanisms that contain fewer independent actuators than the joints. The elastic elements work as convertors from the displacement of the actuators to the joint torques of the mechanisms. In our method, we analyze the joint motions of the mechanisms during the completion of each task and the level of participation of each joint for few specific tasks. The results of this study can be used for the synthesis of dedicated underactuated mechanisms that can operate in a low task coordinate space and for the systematic design of underactuated mechanisms.
