Claim 0:
1. An active rollator, comprising:
an auxiliary frame, comprising a body and a bottom portion;
a driving assembly, disposed at the bottom portion and configured to make the auxiliary frame have a motion;
a sensing assembly, disposed at the body and configured to sense an operation area and output a sensing signal; and
a controller, configured to, according to the sensing signal and a sensing threshold, control the driving assembly to make the auxiliary frame have the motion corresponding to the sensing signal; wherein the sensing assembly comprises two distance sensors, the sensing threshold comprises a body distance area and a middle area, the middle area is in the body distance area, each distance sensor is configured to sense the operation area and output a distance signal, the distance sensors sense substantially different parts of the operation area; when the distance signals fall in the middle area, the controller controls the driving assembly to drive the auxiliary frame to move in a traveling direction; and when the distance signals fall in the body distance area, the controller controls the driving assembly to maintain the movement of the auxiliary frame.
