WebR. Brockett Published 1984 Mathematics The manipulation of rigid bodies by manipulators which are motor driven kinematic chains is a fundamental aspect of robotics. In this paper, we discuss the kinematics of such processes and discuss the classification of kinematic chains using ideas from algebra and group theory. Webrobots is quite difﬁcult. By Brockett Theorem [11], a nonholonomic system can not be stabilized by any smooth or continuous time-invariant state feedback. In order to over-come this difﬁculty, lots of methods have been considered [12–14]. However, from a practical point of view, the tracking problems of nonholonomic mobile robots is also ... flowers sold at costco
