Simulation-based actuator selection for redundantly actuated robot mechanisms

This article presents a simulation-based strategy for sizing the actuators of a redundantly actuated robotic mechanism. The class of robotic mechanisms we consider may contain one or more closed loops and possess an arbitrary number of active and passive joints, and the number of actuators may exceed themechanism’s kinematic degrees of freedom. Our approach relies on a series of dynamic simulat...

The Kinematics for Redundantly Actuated Omni-Directional Mobile Robots

Omni-directional mobile robots have been popularly employed in several application areas. However, the kinematics for these systems have not been clearly identified, specially for redundantly actuated case which is common in omni-directional mobile robot such as Nomadic model. For such mobile robot systems, exploitation of redundant actuation as well as singularity analysis has not been extensi...

Static performance improvement of an industrial robot by means of a cable-driven redundantly actuated system

Every industrial robot has a specific kinematics, which often results in anisotropic performance within its workspace in terms of force and velocity. A cable-driven system can be used to improve the force manipulability of a robot by introducing an actuation redundancy. Such system acts directly on the robot end-effector increasing its flexibility of use in applications where a higher and more ...

Revolute joints with clearance in multibody systems

A computational methodology for dynamic analysis of multibody mechanical systems with joint clearance is presented in this work. Clearances always exist in real joints in order to ensure the correct relative motion between the connected bodies being the gap associated to them a result of machining tolerance, wear, and local deformations. Clearance at different joints is the source for impact fo...

Control of Impact Disturbance by Redundantly Actuated Mechanism

When a robot system collides with its environment, unexpected position errors occur due to the effect of impact. Large actuation effort may grow up to compensate for these errors. The sudden increases of actuator torque may violate the torque limit. In this paper, we propose to employ redundant actuation mode to facilitate disturbance rejection. An optimal load distribution algorithm for redund...
