Abstract: The disclosure discloses a control device for a robot to tease a pet and a mobile robot. The primary sensor is configured to continuously collect a preset number of frames of pet motion images in each motion cycle. The state recognizer is configured to judge the matching between the pet motion images continuously collected by the primary sensor and a pre-stored digital image of pet behavior, and then parse a matching result into behavior state parameters of a pet. The behavior interferometer is configured to adjust and control a behavior state of the pet according to the behavior state parameters and an additional road sign image provided by the secondary sensor. The laser projector is configured to project a laser beam to form a structural light spot, so that the pet changes toward the behavior state adjusted by the behavior interferometer.

Abstract: Disclosed are a Pulse Width Modulation (PWM) generation circuit, a processing circuit and a chip. The PWM generation circuit is used for controlling a rotation speed of an external motor system. The PWM generation circuit includes a second clock prescaler and a PWM signal generator. A frequency division output end of the second clock prescaler is connected to a data input end of the PWM signal generator. The PWM signal generator includes an output frequency divider and a comparator. A clock output end of the output frequency divider is connected to a comparison input end of the comparator. By means of the technical solution, PWM signals with different duty ratios.
