This chapter is devoted to cooperative manipulation of a common object by means of two or more robotic manipulators. After a short introduction to the topic, kinematics and statics of multiple robotic manipulators cooperatively manipulating a tightly grasped rigid object is presented in depth. As for the kinematics and statics, the chosen approach is based on the so-called symmetric formulation. Fundamental concepts related to dynamics of closed kinematic chains are then briefly discussed. A section is devoted to the definition of suitable task-space variables, capable of describing in a meaningful and complete way typical tasks of cooperative robotic systems. Then, the chapter presents a review of the most notable approaches to motion and force control of cooperative manipulators. A set of examples, including a case study based on a simple cooperative system, is proposed to let the student familiarize with the main topics presented in the chapter. The final section is devoted to further reading.

摘要

This chapter is devoted to cooperative manipulation of a common object by means of two or more robotic manipulators. After a short introduction to the topic, kinematics and statics of multiple robotic manipulators cooperatively manipulating a tightly grasped rigid object is presented in depth. As for the kinematics and statics, the chosen approach is based on the so-called symmetric formulation. Fundamental concepts related to dynamics of closed kinematic chains are then briefly discussed. A section is devoted to the definition of suitable task-space variables, capable of describing in a meaningful and complete way typical tasks of cooperative robotic systems. Then, the chapter presents a review of the most notable approaches to motion and force control of cooperative manipulators. A set of examples, including a case study based on a simple cooperative system, is proposed to let the student familiarize with the main topics presented in the chapter. The final section is devoted to further reading.
