Introduction to the internal system composition of industrial robots, scheme sharing of wheeled robots

in recent years, the supply of industrial robots has shown an upward trend in most industries. However, service robots have a short history. Its main differences in function are reflected in two aspects: first, communication and cooperation with people; The second is to replace part of people's work in a complex environment. With the rapid development of IT technology, we have entered a new era of building intelligent robots. In 2015, the world intelligent robot market was about US $26.9 billion. In the next 10 years, CAGR (annual average growth rate) will increase by 9% year-on-year. By 2025, the world robot market will reach US $66.9 billion. In the past, field factory automation in manufacturing industry was the main application field, but at present, the application scope of robots is gradually increasing, and the application fields have involved medical treatment, logistics, home and other service industries. The word "robot" first appeared in the 1920 Czech science fiction writer chapek's "the universal robot of rosom", originally called Robota, and later became a popular robot in English. A more scientific definition was put forward by Japanese scientists Masahiro Mori and Zhou Ping heta in 1967: robot is a flexible machine with seven characteristics: mobility, individuality, intelligence, versatility, semi mechanical and semi human nature, automation, slavery and so on. The International Federation of robots divides robots into two categories, industrial robots and service robots. Industrial robot is a kind of automatic control, programmable and multi-functional actuator used in industrial automation, which contains three or more programmable axes. It can be fixed or mobile. Service robot is a kind of semi autonomous or fully autonomous robot, which can complete service work beneficial to human health, but does not include production equipment. It can be seen from the definition that the classification standard is the application of robots. General robots are composed of mechanical structure, control drive system, perception system, interaction system and so on

first, a new generation robot brain solution based on rockchip rk3288. 1. Functional block diagram

second, a wheeled robot scheme based on NXP lpc54102 and Toshiba tmpm375fsdmg. 1. Functional block diagram

third, a robot design scheme based on NXP low-power Bluetooth control. The robot reference design controlled by Bluetooth low energy (ble) adopts frdm kw40 board and polo zumo robot, and can be controlled through app. The robot controlled by ble is based on kinetic kw40z system on chip (SOC), which includes an arm cortex m0+ processor and is equipped with a 2.4 GHz radio for ble and 802.15.4. It is implemented with hid over GATT configuration file and used as human-machine interface device. The features provided by the software include: the transmission of ble data to app, motor British fixture, etc., which comply with the standard control and battery monitoring of many countries, and so on. 1.

supporting software: ble host protocol stack and configuration file, 802 Before and after the introduction of the rare earth special invoice system by the Ministry of Commerce, 15.4 Mac and smackinetis software development kit (SDK) FreeRTOS kernel and bare metal non preemptive task scheduler summary the application in dangerous environments and becoming an assistant for people's work and life are the two major trends in the development of robots in the future. Of course, it is still quite challenging to make robots work like human beings and become human assistants. First of all, we need to solve the motion ability of robots in complex environments. Secondly, improve perception and decision-making ability. For unmanned vehicles, speed is one of the main characteristics. How to make an appropriate response to the changing environment at high speed until the hardness value obtained twice in a row is the same determines the safety of unmanned vehicles, which is also one of the biggest obstacles to the industrialization of unmanned vehicles. As we all know, the way of machine perception and decision-making is completely different from that of human beings. Human perception has a strong selectivity. The principles of "before the background, after the dynamic, after the static, before the abnormal, after the normal" enable people to quickly find targets in complex environments. This ability is very worthy of robot research and imitation. In short, in recent years, the market demand for robots has continued to rise. Governments, relevant research institutions and enterprises all attach great importance to the development of robot technology, invest a lot of money, and the accuracy is guaranteed. The development of robot technology shows a good trend. The sophisticated problems in robot technology have stimulated many excellent robot R & D teams around the world to innovate and forge ahead. In the future, robots will become an indispensable tool in daily life and bring people a more comfortable and convenient life
