Abstract
The forward tracking system contains a moving carrier and a remote control device. The moving carrier contains a control module, a frame, and at least a driving unit. The control module directs the driving unit to move or turn the moving carrier. The frame has a first and a second IR (infra-red) receivers to detect the user's turning left or right, and a first supersonic detector to detect a distance from the user. The remote control device contains at least an IR transmitter signally linked to the first and second IR receivers. When a user is in front of the moving carrier, the first and second IR receivers, and the first supersonic detector provide lateral movement and forward distance detection, so that the moving carrier automatically follows the user at a constant distance behind as the user moves straight ahead, or turns left or right.
