Modeling and Control of Legged Robots Summary Introduction The promise of legged robots over standard wheeled robots is to provide im-proved mobility over rough terrain. This promise builds on the decoupling between the environment and the main body of the robot that the presence of articulated legs allows, with two Size: 1MB.

In order to meet these requirements, the robot arm has to be flexible, in other words, the rigid-body-assumption in robotics has to be abandoned. Then the deflection and the vibration of the robot arm present a Severe problem to the accuracy and the stability in positioning. Therefore the control of flexible manipulators is becoming a critical Cited by: In this paper, we are concerned with a flexible robot arm formulated by partial differential equations with initial and boundary conditions. An optimal energy control of the robot system is investigated after the system has been transformed to an abstract evolution system in an appropriate Hilbert space. The existence and uniqueness of the optimal energy control are discussed and proved, and.

Control of a flexible beam such as that in flexible-link robot manipulators in many mechanical devices is very challenging, due in part to its intrinsic nature of unmodelled dynamics in a system.

Such a system is said to be subjected to nonholonomic constraints, hence its feedback control is difficult to realize. This paper presents the application of control design based on second-order pole Cited by: 1.
