Abstract

A moving mechanism configured to be assembled to an object to adjust a movement of the object is provided. The moving mechanism includes a bracket, a first wheel, a brake module, a control module, and a sensing module. The bracket is assembled to the object. The first wheel and the brake module are assembled to the bracket. The control module communicates with and drives the brake module. The sensing module communicates with the brake module, and the sensing module is configured to sense an orientation of the object. The control module adjusts a brake force of the brake module on the first wheel based on the orientation of the object.
