Abstract:
An analog simulation of a remote manipulator was developed and used to investigate operator performance as a function of machine design parameters. Independent variables included control order, rate of motion, manipulator dynamics, positioning error tolerance, distance traversed, and duration for which final arm position had to be maintained. Dependent variables were travel time, adjustment time, time on target and total task time. Principal results were as follows: Increasing the complexity of system dynamics produced a ecrement in operator performance which was greater for fixed rate than for porportional rate control. Proportional rate control was found to be superior to fixed rate control afforded no advantage over the optimum single level of rate control.
