Abstract:Abstract After long-term research on mechanism design principle and control theory, this paper designs a multi-functional intelligent turning over system which can realize multi-angle, multi-direction and can be started and stopped manually. This paper mainly expounds the mechanism design and control principle of the turning system. The mechanical structure part includes mechanical function introduction and mechanical structure schematic diagram of Solid works software. The control part mainly includes the hardware design with ARM8/STM32F407 as the core, and the floor is designed independently to ensure the realization of all functions. In the software part, under the development environment of KEIL5, I/O port high and low level is controlled by programming in C language, so as to achieve the motor operation and ensure the stable operation of the turning mechanism. Finally, the feasibility of the control method was verified by mental software, and the feasibility of mechanical structure design was guaranteed by Solid works' simulation of motion trajectory.
