Claim 2:
3. The active rollator according to claim 1, wherein
when the distance signals do not fall in the body distance area, the controller controls the driving assembly to stop the movement;
the sensing threshold comprises a sideways range, and when a difference between the two distance signals falls in the sideways range, the controller controls the driving assembly to drive the auxiliary frame to turn in a turning direction;
the controller obtains a traveling speed according to the distance signals, and the controller controls the driving assembly to drive the auxiliary frame to move at the traveling speed in the traveling direction and drive the auxiliary frame according to the traveling speed to turn; and
the sensing assembly comprises a top sensor, the sensing threshold comprises a top distance area, the top sensor is configured to sense a top area and output a top signal, and when the top signal does not fall in the top distance area, the controller controls the driving assembly to stop the motion of the auxiliary frame.
