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.

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.

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.

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,

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 ...

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.

Manipulation of a flexible object by dual manipulators

Proceedings of 1995 IEEE International Conference on Robotics and Automation, 2002
Proposes a control algorithm of dual manipulators handling a flexible sheet metal. How to bend a sheet metal and how to manipulate the deformed sheet are discussed in this paper. First the authors derive the relation between the static deformation of the sheet metal and the bending moments exerted on the sheet using Lagrange's equation based on a ...

The Art of Manipulation: Learning to Manipulate Blindly

2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018
Performing skillfull manipulation is a very challenging task for robots. So far, even experts could barely program them to e.g. perform the well known peg-in-hole problem in the real world. Autonomously acquiring such skills, let alone generalizing them to new tasks, is still a major challenge.

A study on the manipulability measures for robot manipulators

Proceedings of the 1997 IEEE/RSJ International Conference on Intelligent Robot and Systems. Innovative Robotics for Real-World Applications. IROS '97, 2002
Regarding the dexterousness measure of robot manipulators, two geometric tools, manipulability ellipsoids and manipulability polytopes, are examined and compared with each other. Even though the manipulability ellipsoid approach is the most widely used techniques, it is shown that the manipulability ellipsoid does not transform the exact joint velocity
