pyroelectric sensor demonstration

[Admin]

This is a nice demonstration of using a scanning pyroelectric sensor to detect people.

The robot chassis appears to be made out of an old answering machine . . .

It appears to have two steps:
If it doesnt see a human (heat source)
    keep scanning at large angles
If it does see a human
    drive towards the angle that human was detected at
    scan at smaller angles as long as human is detected

That pyro sensor is fly. This would be good for a firefighting robot, no?
