    • A multisection flexible multidigit arm contains hands at each end, each of which hands contains a set of fingers, suitably three, which are similarly formed flexible multidigit arms constructed to a smaller scale. Each hand contains connectors for coupling the hand to a mating connector mounted on an associated structure to provide appropriate power and control signals to the arm. One hand may grip the connector and the other hand is free to move to various positions and perform various tasks. In an additional aspect the arm may move to different locations by somersaulting between spaced connectors in the system. In an assembly system the robotic arms are used to construct frames or other assemblies.A completely self contained arm includes a self contained source of power. Radio communication means are provided to allow electronic interaction with the arm from a remote location. In an additional aspect the self contained circuitry includes processor means programmed to control the arm to perform a certain task, relieving the operator at the remote location from specifying the details.Control signals to the sections of the arm in an additional aspect to the disclosed invention are provided by an electrical system that uses only a few wires by multiplexing the signals and the actuators, effectively "time sharing" the electrical leads between the large number of actuators.

    • In a mechanical device in which a member is moved by an electrical actuator through an electronic and mechanical linkage, apparatus for compensating for changes in system gain to allow precision movement with non-precision components. There a sensor for accurately determining positions of the member, control logic connected to provide a control signal to the actuator, and an adjustable gain control for adjusting the gain of the control signal. Compensation logic is connected to receive positional signals from the sensor, for applying a control signal to the actuator to move the member to a target position closest to a desired final position, for adjusting the gain of the control signal with the adjustable gain control until the member is located at the target position within acceptable tolerance limits, and for then employing that gain to move the member to the desired final position. The method associated with the apparatus can be done in real-time or by pre-calibrating in advance. When pre-calibrating, there is a look-up table containing a plurality of pre-established gains associated with respective ones of a plurality of target positions and the compensation logic selects a gain from the look-up table employs the gain to move the member directly to the desired final position.
