A control scheme is derived for a 'master-slave' telerobotic dynamic system
with haptic behaviour. The telerobotic system consists of a 'master' robot
, operated by a human arm, and a kinematically identical 'slave' robot, loc
ated at a remote site. When the operator moves the handler of the 'master'
back and forth. the remote 'slave' mimics the motion in a constrained or un
constrained environment. The disturbance and reaction forces from the envir
onment and the loads are fed back to the handler of the 'master' and felt b
y the operator. Thus, the operator gets a feel of what is 'out there' witho
ut being 'there'. The advantage of the presented control scheme is the inte
gration of the dynamics of the operator arm. actuators, and the environment
in the closed-loop control system for stability analysis. It is shown that
the experimental and theoretical results are in good agreement, and that t
he designed controller is robust to constrained /unconstrained environment
and load disturbances.
