Passing manipulation by 1 degree-of-freedom manipulator - catching manipulation of tossed object without impact

There are some researches which perform complex manipulation tasks to control dynamic characteristics of the object (sliding, rolling, releasing, etc). They are called dynamic manipulation. We introduced tossing manipulation as one of dynamic manipulation. In this paper, tossing manipulation is expanded to catch the tossed object without impact. It is called passing manipulation. A pair of 1-DOF manipulators is used as a tossing manipulator and a catching manipulator. First, the tossing manipulator swings its arm to roll/slide an object on it, and tosses the object. Next, the object is thrown to the catching manipulator. Then, the catching manipulator swings its arm to contact the object without impact, and manipulates it on the arm. Finally, the object stands still on the catching arm. This paper shows a kinematic model of passing manipulation, and the kinematic model is analyzed. Furthermore, a method to search optimal passing manipulation is described. Finally, optimal solutions are simulated and discussed.
