A robotic assistant includes a base; an elevation mechanism positioned on the base; a display rotatably mounted on the elevation mechanism; a camera positioned on the display; and a control system that receives command instructions. In response to the command instructions, the control system is to detect movement of a face of the user in a vertical direction based on the images captured by the camera. In response to detection of the movement of the face of the user in the vertical direction, the control system is to rotate the display and actuate the elevation mechanism to the move the display up and down to allow the camera to face the face of the user during the movement of the face of the user in the vertical direction.

A control method for an intelligent rollator, and a control device, an intelligent rollator, a controller thereof. The intelligent rollator is configured with a vehicle body, a front wheel and rear wheels driven by a motor. The method includes the following steps: obtaining the moving speed of the intelligent rollator; obtaining the attitude of the intelligent rollator; and reducing the torque output of the motor, when the attitude indicates that the front end of the intelligent rollator is tilted upward, and the moving speed of the intelligent rollator is less than a first threshold. The intelligent rollator can determine whether it is necessary to enter an intelligent crossing-curb mode, in which the torque output of the motor is reduced, so as to prevent the vehicle body out of control due to the increase of torque caused by the too large speed when getting over curbs.
