The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Precision of computer controlled motion require s low backlash mechanical transmissions in the kinematic chains that link the mo tors to the driven elements/end-effectors. If backlash (mechanical slack, play) is present, the driven element does not exactly follow the motion of the motor c ontributing to kinematic errors and possible dynamic effects. Mechanical backlas h impacts the kinematic performance of robots, including medical robots. However , most mechanical transmissions are based on gears, and with gears the backlash is difficult to control. Few mechanical transmissions have minimal backlash or b acklash-free, including ball-screws, ball-worms, cables, and harmonic drives.
