Abstract: A three degree-of-freedom robotic manipulator is constructed from three rotary drives. The rotary drive consists of a relatively small diameter cylindrical driving member coupled to a larger diameter cylindrical driven member. The driven member of a second rotary drive is mounted perpendicularly to the driven member of a first drive. The driven member of a third drive is mounted to the periphery of the driven member of the second drive with its axis of rotation parallel to the driven member of the second drive. The driving member of the third drive is located with its axis of rotation coincident with the axis of rotation of the driven member of the second drive. Motors powering the second and third driving members are mounted to the driven member of the first drive roughly centered over its axis of rotation. An extension arm for mounting the end effector is fixed to the driven member of the third drive. This arrangement reduces the number of required components and minimizes motor movement to reduce inertia.

Abstract: In a vehicle having separate front and rear transmissions, a system for slaving one of the transmissions to the other so that the slave transmission will operate in the same drive range as that existing in the master transmission.
