In other words, the end effector solved the wrong problem. •A “concurrent engineering approach ... All types of mechanical transmissions are used, but the tendency is toward low and zero backlash-type drives. Some robots use direct drive methods to eliminate the amplification of inertia and mechanical backlash ... robots were simple sequential machines controlled by a combination of servo motors, adjustable mechanical stops, limit switches, and programmable logic controllers. These machines were generally...
