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-

Manipulabilities Of Serial-parallel Manipulator Systems

Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005
This paper presents two different ap- proaches of deflning the manipulabilities and resistivi- ties of serial-parallel manipulator systems. In the flrst approach, the manipulability (resistivity) of the serial- parallel structure is dehed by imposing the kinematic constraint on the local manipulabilities (local resistiv- ities), each of which is ...

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.

Manipulation of multiple objects by two manipulators

Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002
This paper focuses on the manipulation of multiple objects, for example, to rake up many objects on a table, lift them up and put them in order, which is difficult to perform for a single manipulator system. This kind of operation becomes possible or much more effective by the cooperation of two manipulators.

A soft computing approach for inverse kinematics of robot manipulators

Engineering applications of artificial intelligence, 2018
The solution of the inverse kinematics problem is an essential capability for robotic manipulators. This capability is used to solve tasks such as path planning, control of manipulators, object grasping, etc.

Symbol manipulation and formula manipulation

ACM SIGSAM Bulletin, 1983
For years, Chinese research workers have noticed that there are systems for symbol manipulation and formula manipulation abroad. But use of computers in China is later. In early years, only assemblers, ALGOL, BASIC and FORTRAN languages were used, which were not suited to help manipulate formulas.

Multiple tasks manipulation for a robotic manipulator

Advanced Robotics, 2004
Robotic manipulators can execute multiple tasks precisely at the same time and, thus, the task-priority scheme plays an important role in implementing multiple tasks. Until now, several algorithms for task-priority have been used in solving the inverse kinematics for redundant manipulators.

A parallel manipulator for mobile manipulating UAVs

2015 IEEE International Conference on Technologies for Practical Robot Applications (TePRA), 2015
Manipulating objects using arms mounted to unmanned aerial vehicles (UAVs) is attractive because UAVs may access many locations that are otherwise inaccessible to traditional mobile manipulation platforms such as ground vehicles. Most previous efforts seeking to coordinate the combined manipulator-UAV system have focused on using a manipulator to ...

Dexterous manipulation with general manipulation methodology

Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems. IROS '96, 2002
We discuss various kinds of manipulation in this paper. Conventional manipulation is made when an object is rigidly grasped by a robot hand. Previously, different kinds of manipulation, in which a manipulated object is not fixed onto a robot hand, were studied. They have dexterity but uncertainty. In this paper, we give a classification of manipulation,

Stackable manipulator for mobile manipulation robot

2012 IEEE International Conference on Robotics and Automation, 2012
This paper proposes a new manipulator concept applied to a mobile robot manipulation system for reducing robot size and weight or increasing its work capacities such as a payload, operating radius, and operating speed. In detail, we propose a new robotic manipulator that uses stackable 4-BAR mechanisms for mobile manipulation robot.
