It is well known that a sequence of two impulses can be used to redirect the spin axis of an axisymmetric rigid body. The first impulse initiates the coning motion by imparting an initial transverse component of angular velocity. The second impulse b

In this paper we explore cooperative manipulation of a flexible structure using a team of two nonholonomically-constrained, differentially-driven robots. Cooperative manipulation is achieved by tracking relative trajectories that are designed for bot
