Robot obstacle detection system
First Claim
1. A sensor subsystem for an autonomous robot which rides on a surface, the sensor subsystem comprising:
- an optical emitter which emits a directed optical beam having a defined field of emission;
a photon detector having a defined field of view which intersects the field of emission of the emitter at a region; and
a circuit in communication with the detector providing an output when an object is not present in the region thereby re-directing the autonomous robot.

Abstract
A robot obstacle detection system including a robot housing which navigates with respect to a surface and a sensor subsystem having a defined relationship with respect to the housing and aimed at the surface for detecting the surface. The sensor subsystem includes an optical emitter which emits a directed beam having a defined field of emission and a photon detector having a defined field of view which intersects the field of emission of the emitter at a region. A circuit in communication with a detector redirects the robot when the surface does not occupy the region to avoid obstacles. A similar system is employed to detect walls.
