During the last two decades a large amount of effort and attention has been
paid to the problem of designing and controlling dextrous robotics hands.
The possible application background ranges from telerobotics to upper limb
prosthetics, while actual industrial developments are mainly limited to spe
cific grippers and tools. Classical problems related to dextrous hand desig
n are kinematics of multifingered hands, development of proper actuation te
chnologies and redundant tendinous systems for transmission. As far as hand
control is concerned, grasp preshaping, planning and synthesis are of majo
r concern, while sensor guided hand operation is still a matter of research
. The present work reviews the above mentioned hand design and control issu
es trying to throw some light on the Babel-like confusion encountered when
looking at present literature on dextrous hand design and specially control
. Most actuation and transmission technologies, as well as control approach
es, are studied and classified.
