ABSTRACT:
An interactive toy is capable of detecting and tracking any nearby heat source such as a human body. This device can, in addition to tracking, move to interact with the heat source. The toy can either chase or move away from the heat source according to a set mode of operation. PIR sensors are mounted in a rotating head that is mounted in turn upon a wheeled, tracked or legged body that can move. The device further includes sensors to detect unheated objects in its path and will act to avoid hitting them. The PIR sensors have a limited field of view so as to prevent overlapping fields of view and are filtered or tuned to receive only a certain bandwidth or infrared radiation.
