Abstract:Along with the computer technology and the artificial intelligence technology rapid development, caused to move the robot all had the very big enhancement in the function and the technical level aspect, moved the robot the vision and the sense of touch technology is typical representative. Moves the robot often to use for in the industrial production to complete the transportation and on duties and so on yummy treats, simultaneously also widely uses in the agriculture, the medical service and so on different profession.
The motion robot technology was the recent years research hot spot, walked independently may take most basic function. This time graduation project take realizes walks the robot independently to walk the function as the essential target, completes the robot manufacture. This time graduation project take realizes walks the robot independently to walk the function as the essential target, completes the robot manufacture. Mainly divides into three big modules in detail, the electrical machinery power module, infrared evades bonds the system, the Hall sensor measures fast module. Realizes the robot car take these three big modules as the principal route to walk independently. The platform mainly depends upon the ARM development board and the monolithic integrated circuit great luck simulator, from hardware obtaining, completes each kind of hardware the manufacture and the debugging, again matches by the software, complete this system together with the procedure. Finally to move the robot the trend of development to carry on has forecast.
