I want to detect and follow a fly in the room in the hope that in a next stage I can shoot it down with a laser. To me detection seems the hardest problem. I have experimented with IR to get some feeling for it. As far as I see it now the problem consists of two parts: 1. detect whether there is some movement somewhere, this should give an imprecise detection of where the object is located 2. position a high precision distance detector into the direction of the movement 3. 'search' the environment of the detected movement 4. when something found follow it
My problem is that I don't know any hardware which could solve this problem 1. is there such a movement detector that can give the coordinates of the detected object. Ideally this should be a 3D radar but I couldn't find any reference, that would eliminate step 3 and 4 as well 2. positioning could be done with pan/tilt and 2 servo's, with this I could position along the x/y and z axis 3. is there a high precision distance detector that can sense an object of size 0.5 cm at 1 to 3 meters? Can a Ping))) do this or are there better detectors 4. can this distance detector follow the object? I am thinking at 5 sensors arranged like a 5 of a die and reading the values of each sensor at short intervals.
I think I can tackle the algorithmic part, but I am a newbie on sensors.
Any help would be appreciated, thanks.
