Abstract

The psychophysical Method of Constant Stimulus Differences was used to determine difference thresholds and Weber ratios for both direct and remote lifting of two standard weight stimuli. A Model 8 Master-Slave Manipulator was used for remote lifting. For 1000-gram weight, difference thresholds were 65.42 and 110.45 grams for direct and remote lifting, respectively. Corresponding difference thresholds for a 3000-gram standard were 149.33 and 195.69 grams. The difference threshold indicates the fineness of weight discrimination which can be expected of a worker. Increases in difference thresholds as a function of remote lifting reflect the loss of "feel" associated with remote handling. The difference threshold is proposed as a criterion of the fidelity of cues reflected to the operator by the remote-handling system.
