This paper presents design and construction of an autonomous robot for using in greenhouse condition. The robot designed to prevent human hazards involved in spraying potentially toxic chemicals in the confined space of a hot and steamy glasshouse. In order to navigate the robot, hot water piping rails along the rows were used as a method of guidance for autonomous robot. The robot is able to force and back along the hot water piping rails of rows in greenhouse avoiding the expensive and complicated navigation systems. Power was transmitted from two DC motors to two driving wheels through a gearbox and shaft system. The AVR microcontroller controls all of the inputs and outputs of the system. To program the micro used from BASCOM-AVR version and for circuit simulating used from PROTEUS 7 professional. The obtained Results indicated that the robot is capable to cover more than 90% of surface which needed to spray.
