The NXT Dolly is a programmable camera dolly system for smooth camera movements based on LEGO® MINDSTORMS NXT.
It runs on rails and can either be programmed or controlled by a remote control.
The dolly can be run seamlessly along the rails.
The camera can be rotated and moved up and and down.
Each of these movements is independent from the other ones and can be adjusted in speed and duration.
Different sensors can be mounted on the dolly to support the programmatic control of the camera movements or to light the environment.
The length and direction of the rails can be adjusted to allow for arbitrary tracking shots.
