Manoeuvring highly redundant manipulators

Robotica, 1997
A task based approach to the issue of redundant robots starts from the premise that there are obstacles that cannot be removed from the working area and which therefore must be avoided. This statement produces the requirement for a device with a certain degree of mobility, and stresses the need to ensure that the aim is twofold: reach the goal and ...

Identifying Feasible Workpiece Placement with Respect to Redundant Manipulator for Complex Manufacturing Tasks

IEEE International Conference on Robotics and Automation, 2019
Successfully completing a complex manufacturing task requires finding a feasible placement of the workpiece in the robot workspace. The workpiece placement should be such that the task surfaces on the workpiece are reachable by the robot, the robot can ...

Manipulability Analysis for Cable-Driven Hyper-Redundant Manipulators

2021 IEEE 17th International Conference on Automation Science and Engineering (CASE), 2021
Cable-driven hyper-redundant manipulators (CDHMs) have been widely applied in aerospace, surgery, or other fields to complete tasks in narrow and multi-obstacles environments. Maneuverability is an important metric for CDHMs and is more difficult to analyze than traditional industrial robots because of their more complicated kinematics.

The dynamic manipulability ellipsoid for redundant manipulators

Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002
Manipulability ellipsoids are effective tools to perform task space analysis of robotic manipulators in terms of velocities, accelerations and forces at the end effector. A new definition of dynamic manipulability ellipsoid for redundant manipulators is proposed which leads to more correct results in evaluating manipulator capabilities in terms of task-

Spatial impedance control of redundant manipulators

Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003
This work is focused on impedance control of redundant manipulators. A spatial impedance formulation is presented where general 6-DOF end-effector tasks can be handled. A singularity-free angle/axis representation of end-effector orientation is used which allows geometric task consistency to be preserved.

Manipulability constraint locus for a redundant manipulator

Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91, 2002
A manipulability constraint locus to characterize the performance of a subtask for a redundant manipulator is suggested. The manipulability constraint locus is the loci of configurations satisfying the necessary condition for optimality of the manipulability measure in the configuration space.

Redundant grasps, redundant manipulators, and their dual relationships

Journal of Robotic Systems, 1992
AbstractThis article presents a meaningful, practical, and theoretically sound solution that solves the problem of grasping a rigid object with a hand that has redundant (>6) grasping contacts. This is accomplished by introducing compliance at each contact point in such a way as to provide the engineer with the capabilities of object manipulation ...
