Two sources (1',1'') provide light at wavelengths of 420-520 nm and 900-1000nm respectively. Each source is modulated (6) at a different frequency. A split optical fibre(2,3) illuminates the leaf (A) and returns reflected light to the phase-sensitive detector (4) and signal processor (5). Two voltages are obtained that are a function of reflected light. Comparisons with a reference level determine...

A robot includes an obstacle sensing mechanism for sensing an angle formed between a first wall and a forward travel direction of the robot. The robot then travels parallel to the first wall while the obstacle sensing mechanism senses a front distance of the robot from a wall located in front of the robot and sideward distances of the robot from walls located to respective sides of the robot. In r...
