[0027] In order to keep the intelligent robot at an appropriate distance during the interaction process with the user, an embodiment of the present invention first proposes a method for following the intelligent robot, and its flow chart is as follows figure 1 As shown, the method includes the following steps:
[0028] Step S110, using the receiving device installed on the intelligent robot to acquire the ultrasonic ranging signal.
[0029] Step S120, using the ultrasonic ranging signal to determine the real-time distance between the intelligent robot and the target to be followed according to the triangulation method.
[0030] Step S130, generating and outputting multimodal data for the intelligent robot to follow the target according to the real-time distance.
[0031] Specifically, an ultrasonic receiving device is installed on the intelligent robot in the embodiment of the present invention, and in step S110, the ultrasonic receiving device is used to receive an ultrasoni...

[0063] When using ultrasonic ranging, the two receiving points respectively receive the ultrasonic signals transmitted by the transmitting device. Ideally, after the transmitting device transmits the ultrasonic signal, receiving point 1 and receiving point 2 start timing at the same time, so as to ensure that the first distance A calculated according to expressions (1-1) and (1-2) and the second distance B are accurate, while ensuring that the relative distance between the first distance A and the second distance B is accurate.
[0064] In this embodiment, an infrared signal is used as a synchronization signal to solve the above problem.
[0065] Specifically, receiving point 1 and receiving point 2 first receive an infrared signal as a synchronization signal before receiving the ultrasonic signal emitted by the transmitting device. Receiving point 1 and receiving point 2 use the infrared synchronous signal as the timing start point to measure the time of receiving the ultras...

[0071] In this embodiment, a transmitting device for generating an infrared synchronization signal is proposed.
[0072] The transmitting device can be installed on the target (user) to be followed, and the transmitting device mainly includes an ultrasonic transmitting unit and an infrared transmitting unit.
[0073] Among them, the ultrasonic transmitting unit is mainly used to transmit ultrasonic signals to the intelligent robot at a set frequency.
[0074] The infrared sending unit is connected with the ultrasonic emitting unit, and a local synchronous signal is transmitted between the infrared sending unit and the ultrasonic emitting unit to make the infrared sending unit and the ultrasonic emitting unit act synchronously. When the ultrasonic transmitting unit transmits the ultrasonic signal, the infrared transmitting unit simultaneously generates and transmits an infrared synchronous signal.
[0075] According to the second embodiment, it can be seen that the propagation...
