Abstract
A system and method for measuring linear and angular displacement of a moving object, such as an autonomous moving object. In one embodiment, the system comprises at least one optical mouse sensor mounted adjacent to and at a predetermined distance from a surface of the autonomous moving object or a working surface. A processor on the autonomous moving object is operatively coupled to the optical mouse sensor. The optical mouse sensor outputs linear and angular displacement values to the processor during movement of the autonomous moving object to determine a direction and distance traveled by the autonomous moving object.

A system for measuring angular displacement of a rotatable antenna, the system comprising:
- a rotatable antenna mounted on a fixed base having an upper surface;
- at least one optical mouse sensor mounted on the rotatable antenna adjacent to and at a predetermined distance above the upper surface of the fixed base;
- and
- a processor operatively coupled to the optical mouse sensor;
- wherein the optical mouse sensor:
- measures rotation of the antenna by tracking around the upper surface of the fixed base as the optical mouse sensor moves with the antenna;
- and
- outputs linear and angular displacement values to the processor to determine a direction that the antenna faces and how far the antenna has rotated.
