Cheap Homemade IR Compound Eye
The purpose of this cheap, easy to make eye is to allow your robot to track movement of nearby objects (within 200mm). After much experimentation and various degrees of success I have finally got a good working design for my IR tracking system which is really a simple 4 element compound eye.
Compound eyes are found in Arthropods such as insects. They are of relatively low resolution compared to the human eye but more responsive to movement. Unlike Insect eyes, my design includes it’s own light source and is blinded by excess ambiant IR making them better suited to indoor and nocturnal activities.
