This paper describes the operational theory and design of quadridirectional air thrusters ('quads') for propulsion of free-floating robots. Two quad thrusters were built for propulsion of the free-floating robot of Ohio Univerity. In this design, the air is drawn from a central air tank and routed to four nozzles of a quad thruster via a pressure regulator, a distribution manifold, four solenoid valves, and a quad manifold. The pressure regulator is controlled by a d.c. servomotor and the solenoid valves are turned on/off using the digital output ports of the computer. The performance characteristics of this quad thruster were determined experimentally. The experiment measurements of the thrust as a function of the regulated pressure show a good match between the measured data and the data predicted by the supporting theory.
