Robot programmable infrared obstacle avoidance apparatus

Abstract

The invention relates to a programmable infrared obstacle-avoided device of robot, which comprises a multi-path infrared emission unit, an infrared receiving unit, a band-pass filter circuit, a control / judgment circuit and a central processing element. Wherein, the band-pass filter comprises a band-pass filter circuit and a second online programming interface formed by programmable analogue devices to receive the signal transferred by every receiving unit and transfer the filtered signal to the control / judgment circuit; the control / judgment circuit comprises a control unit, a judgment unit and a first online programming interface formed by programmable digital devices; the control unit can distribute fixed frequency band or code to each emission unit and receiving unit and operate the trigger circuit of each emission unit; the judgment unit can judge that if the signal transferred from band-pass filter is the echo-wave signal of emission unit; and the circuits of control unit and judgment unit can be modified by the first online programming interface while the band-pass filter circuit can be modified by the second online programming interface. The invention is an optical-electrical obstacle-avoided device with online regulation, high integrated degree and strong anti-interference ability.

Description

technical field

[0001] The invention relates to a photoelectric obstacle avoidance device, in particular to a navigation and obstacle avoidance device for a fully autonomous mobile robot. Background technique

[0002] With the development of mobile robot technology and the improvement of its performance, its application is becoming more and more extensive. For example, in the fully autonomous football robot competition, the robot is required to have high flexibility, strategy and good cooperation. If the robot cannot effectively avoid obstacles on the field, it will inevitably lead to the loss of the game. Therefore, the problem of robot obstacle avoidance on the playing field is very important. According to the published literature, before the present invention, mobile robots generally adopt each independent photoelectric switch to avoid obstacles. Since these infrared obstacle avoidance systems are made of common analog and digital devices, they are not easy to change on...
