Photoelectric positioning device of football robot based on digital signal process

Abstract

The invention relates to a photoelectric localizing device for football robot based on digital signal processor. It is made up of photoelectric sensor, sensor bridging mechanism and control system. The control system includes DSP digital signal processor, buffer driving chip, JTAG test simulating interface, communication hardware port and communication port driving chip. The sensor bridging mechanism is assembled on the bottom of the robot against the ground; the photoelectric sensor is assembled on the sensor bridging mechanism near the ground, the output signal of the photoelectric sensor is transmitted to correspondent signal capturing unit of DSP to realize signal collection after being modulated by buffer driving chip. The calculated result from the DSP processor is sent into the communication hardware port through communication port driving chip, and realizes the communication and data transmission with superior machine, thus the robot can acquire the current location information. The whole device is an independent module, it can accomplish the localizing work independently without hardware and software platforms of universal computer, it is accurate, reliable, and transplantable and the cost is low.

Description

technical field [0001] The invention relates to a photoelectric positioning device, in particular to a photoelectric positioning device for soccer robots based on a digital signal processor, which is suitable for fully autonomous soccer robots participating in World Cup soccer matches, and can also be used for other robot projects, and belongs to the technical field of soccer robots. Background technique: [0002] With the popularization of soccer robot games and the development of soccer robot technology, the performance of soccer robots is becoming more and more perfect. In the fully autonomous soccer robot competition, the robot is required to have high flexibility, strategy and good cooperation. If the robot cannot accurately determine its position on the field, it will inevitably lead to the loss of the game. Therefore, the problem of robot positioning on the playing field is very important. According to the published documents, before the present invention, the footba...

Problems solved by technology

The shortcomings of this patented drive technology are: it is implemented on a general software platform, with high cost, low stability and low cost performance; the image is extracted through visual equipment, and the positioning is based on feature points, which has large errors and low precision. To significantly improve the precision, it must be selected High-end equipment is expensive; due to the defects of the visual recognition system itself, it is greatly affected by factors such as environmental color difference and the strength of the light source. It is difficult for existing solutions and equipment to adapt to the trend of future robot competitions under natural light; the feedback position information error of visual positioning Large, resulting in difficulty in collaboration among multiple robots based on this information, and large errors

[0004] This patented technology is applied in the field of weld seam inspection, which can only recognize the shape, and has large positioning errors, is susceptible to interference, and has poor collaboration. It is not suitable for real-time processing of the real-time position information of the robot on a wide field in terms of technical principles and implementation methods. Not valid for Soccer Robot World Cup matches
