Hybrid position/force control of manipulators

MH Raibert, JJ Craig - 1981 - asmedigitalcollection.asme.org
A new conceptually simple approach to controlling compliant motions of a robot manipulator
is presented. The “hybrid” technique described combines force and torque information with …

Articulated hands: Force control and kinematic issues

JK Salisbury, JJ Craig - The International journal of Robotics …, 1982 - journals.sagepub.com
Kinematic and control issues are discussed in the context of an articulated, multifinger
mechanical hand. Hand designs with particular mobility properties are illustrated, and a …

Adaptive control of mechanical manipulators

JJ Craig, P Hsu, SS Sastry - The International Journal of …, 1987 - journals.sagepub.com
When an accurate dynamic model of a mechanical manipu lator is available, it may be used
in a nonlinear, model-based scheme to control the manipulator. Such a control formula tion …

Adaptive control of manipulators through repeated trials

JJ Craig - American control conference, 1984 - infona.pl
Virtually all manipulators at work in factories today repeat their motions in cycles.
Unfortunatly, whatever errors may exist in repeating a trajectory are also repeated from cycle …

A systematic method of hybrid position/force control of a manipulator

JJ Craig, MH Raibert - … and The IEEE Computer Society's Third …, 1979 - ieeexplore.ieee.org
The feasibility of applying robot manipulators to complex handling and assembly problems
