Claim 9:
10. 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 horizontal scanning sensor, the sensing threshold comprises a traveling feature, the horizontal scanning sensor is configured to horizontally scan the operation area and output a horizontal scanning signal, and when the horizontal scanning signal falls in the traveling feature, the controller controls the driving assembly to drive the auxiliary frame to move in a traveling direction.
