Title:
CONTROL METHOD AND APPARATUS FOR SMART WALKER, SMART WALKER, AND CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2023/272772
Kind Code:
A1
Abstract:
A control method and apparatus for a smart walker (100), the smart walker (100), and a controller. The smart walker (100) comprises a walker body, front wheels, and rear wheels, and the rear wheels are driven by a motor. The method comprises the following steps: obtaining the moving speed of the smart walker (100); obtaining a pose of the smart walker (100); and when the pose indicates that a front end of the smart walker (100) inclines upwards, and the moving speed of the smart walker (100) is less than a first threshold, reducing a torque output value of the motor. Therefore, the smart walker (100) can intelligently determine whether to enter a smart curb crossing mode, and reduce the torque output value of the motor in the smart curb crossing mode, thereby avoiding a situation in which the walker body is out of control due to a greatly increased torque caused by a fast speed during curb crossing.
