Abstract

With the development of micro electronic technology and embedded system in China, the traditional manipulator in the industry can not meet the needs of customers. In order to improve the traditional mechanical arm in the control of the shortcomings of the problem, in this graduation project, will use relatively advanced, fast, intelligent control mechanism. The control brain of the system is the core controller of the 32 series embedded development system, which mainly uses digital control technology to convert the input continuous analog voltage signal into discrete digital signal to achieve wireless control. The mechanical arm based on STM32 microcontroller has intelligent control, wireless transmission and other functions, and has the characteristics of high cost performance, accuracy, low energy consumption, simple production, convenient and fast use, which has brought a great impact on people's life and is very popular in the market.

The technical point of this design mainly lies in the PWM output of STM32 and the signal receiving of STM32 to MPU6050. The design content needs STM32 microprocessor, digital steering gear, wireless module, MIPU6050 and other components to provide digital steering gear control system based on STM32 PWM technology and SIGNAL receiving and conversion system of STM32 to MPU6050. The system uses STM32 as the core and is programmed in Keil Uvision4 development environment.

Based on the STM32 MCU is different from 51 MCU, so the function of each part of STM32 system is introduced. The content is simple and easy to understand, clear the key content, guarantee the entry of STM32, zero foundation can also be developed.

The intelligent control system design mainly from the domestic and foreign development, the choice of hardware control components, according to the control principle to draw the hardware circuit, control system software program design and development, etc. The control system is composed of STM32 embedded development system, wireless control part and digital steering gear.
