To realize the intelligent work of mobile robot,the track calculating location technology is studied in this paper.Sensors like gyroscope and photoelectric encoder are taken in moving the location of robot who has known the route.The system composes of driver module,sensors,feedback module and control module.With high anti-interference ability,the modular design has fully integrated the resource of system.Meanwhile,servo driver motor is used to reduce the moving error.This kind of robot can be well used on industrial processing and...
