An autonomous vehicle for operating in a predetermined work area while avoiding both fixed and moving obstacles. A plurality of laser, sonic and optical sensors detect targets and obstacles in the work area and provide coded signals to processors and controllers which direct the vehicle over a most expedient route to a target while avoiding any obstacles. The vehicle is especially useful in moving around the deck of an aircraft carrier to deliver ammunition to aircraft from an ammunition magazine.

Multi-purpose autonomous vehicle with path plotting

Apparatus for detecting fluid pound in a sucker-rod oil well, using values of sucker-rod position and of sucker-rod load to calculate a reference position and a selected load value. The apparatus continually updates the reference positions and selected load values to compensate for drift in characteristics of transducers used in determining rod load and rod position and for a gradual change in well characteristics. When the sucker-rod moves downward to the updated reference position, the actual rod load is checked against the updated selected value and a warning signal develops when the amount of load exceeds the updated selected value.
