The Design and Construction of Wireless Spray Weeds Robot Controlled by Microcontroller

Abstract

This paper presents the design and construction of wireless spray weeds robot controlled bymicrocontroller which can move and spray weeds in the desired environment and dangerous to human.It obtains a command from computer with C language controlled by keyboards. The signal to communicatebetween computer and robot is radio wave at 433.92 MHz through the parallel port. The robot usemicrocontroller PIC16F877 controlled by PICBASICPRO language for controlling the entirely system. In theactual test, the instruction can be sent from the computer keyboard to the robot which is away for 30 metersand the microcontroller able to receive the instruction from the computer for evaluating and controlling all therobot functions including move forward, move backward, stop, turn right, turn left, open pump, turn cameraleft, turn camera right and turn camera middle in the desired.
