Claim 5:
6. 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 a plurality of distance sensors, the sensing threshold comprises a 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, and when the distance signals fall in the body distance area, the controller controls the driving assembly to drive the auxiliary frame to move in a traveling direction.
