Abstract
A lift detection mechanism of a mowing robot includes a wheel set, a movable member, a transmitter, and a receiver. The wheel set has an axle rotatably and movably penetrated into a fixed seat, a wheel connected to the axle and located outside of the fixed seat, and a fixing member disposed to the axle and located in the fixed seat. The movable member is disposed to the axle and located in the fixed seat. One of the transmitter and the receiver is disposed to the movable member, and the other of the transmitter and the receiver is disposed to the fixed seat. As such, when the mowing robot is lifted by a user, the movable member is driven by an elastic member to move downwards until the transmitter and the receiver are staggered. As such, blades are controlled to stop working for preventing the user from being cut.
