Terminator Kit Assembly (TKA) includes all features that mechanical manipulator needs to use hand tools for maintenance, repair, or assembly work. Tool box holds hand tools and, on command, releases them to hand interface which accepts and operates them. TKA is being studied as possible prosthetic device.
Manipulator offers improved performance over other models in its category. It features larger force and reach capabilities and is readily convertible for underwater use. Unique kinematic arrangement provides extremely large working envelope. System has six degrees of motion: azimuth joint, shoulder joint, upper arm rotating joint, elbow joint, wrist pitch, and wrist twist.
Multi-channel proportional control system for operation of dc motors for use with externally-powered orthotic arm braces is described. Components of circuitry and principles of operation are described. Schematic diagram of control circuit is provided.
Platform with several ground effect pads and plenum chambers
Ultrasonic wrench for applying vibratory energy to mechanical fasteners
Lunar gravity and earth orbital simulator development and testing
Mathematical model is formulated for an air pad which is capable of lifting a structure to a height of 0.125 inch. Design is superior to conventional air cushion devices because it eliminates flutter, vibration, heaving, and pitching.
Ultrasonic wrench system produces leaktight seals in flared tubing connections. It induces a flexural vibration mode in the coupling nut. The system consists of a frequency converter, a junction box, and wrench assembly.
