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.

Abstract: A foldable trolley includes a chassis frame, which includes a front wheel set and a rear wheel set between a slidable plate is arranged for driving the rear wheel set to collapse toward the front wheel set. The first frame is coupled to a first driver device and is mounted on the slidable plate. The second frame is coupled to a second driver device and connected to the first frame. The first driver device drives the first frame to bend toward the front wheel set and the first frame drives the slidable plate to move simultaneously so as to have the rear wheel set to collapse towards the front wheel set. The second driver device drives the second frame to bend toward the rear wheel set so as to achieve an effect of multiple-stage folding to effectively reduce the overall size after folding.
