Abstract
A rotary drive apparatus has a drum with a first plurality of generally parallel grooves spaced a predetermined distance apart. A capstan adjacent the drum has a second plurality of generally parallel grooves spaced the same predetermined distance. The capstan may be disposed adjacent the drum with its grooves disposed between the grooves on the drum. The drum and the capstan may have parallel axes of rotation. A continuous cable in the grooves of the drum and the capstan couples the drum and the capstan for joint rotation. A pulley and spring adjacent the capstan tension the continuous cable.
