In this study, we explore the possibility of dynamic object manipulation of objects using a series of manipulators. Here, two three-active-link manipulators have been considered and the generality of the idea to a series of manipulator is developed easily. So without any gripper, and in an unstable grasp manner, we try to throw an object by a manipulator and catch it with another. Also we can consider the impacts generated in the moment of throwing and catching objects, as some disturbance and therefore we damp it. Finally we deal with the whole manipulation process as a system with some noise and disturbance and try to demonstrate its stability. All results have been validated with the aid of simulations.

In this paper, we try to show that it is possible to deal with biped locomotion as a dynamic object manipulation problem. We show that during locomotion, a biped locomotion can be seen as manipulating of upper part of biped robot using a leg, which now plays the role of a manipulator. So the whole locomotion process can be seen as a dynamic manipulation of an object (upper part of a biped robot) using a numerous series of manipulators each of which placed in a proper place where the object tends to land, so it catches the object and throws it to the next point which another manipulator waits for catching it. The authors in the previous works have explored the problem of dynamic manipulation of parts. The results have been validated with the aid of simulation.
