Design and implementation of DC linear actuator and stepper motor for remote control of the driverless tractor robot

This research was to propose the DC linear actuators and a stepper motor as mechanical drive systems such brake pedal, clutch forward-reverse gearshift, gear position selection, tail-lifting system lift chemical tank, speed selection of power take-off (PTO). The were used instead muscles, arms, legs human being. control steering direction driverless tractor robot. based on programmable logic controller radio remote for robots. Both MATLAB/Simulink simulation experimental results validation satisfactorily achieved. test robot in spraying water football field satisfactory response rapid braking.
