| Summary: | A grass cutter is a machine that uses a revolving blade or blades to cut a lawn grass. Many designs have been made, each suited to a particular purpose and this robot used string trimmer as the cutting blade. This robot is designed to operate by a rechargeable battery and can be described as an intelligent robot because the micro-controller will receive information from sensors connected to it in avoiding obstacle to ensure a neat pattern of cut and use the information to actuate the left and right motors driving the wheels and the centre motor driving string trimmer and at the same time it obeys all parameters of work and its program database. As it is well known that random motion for a lawn mower would sometimes lead to uncovered spaced, it all depends on how random is random. Few features were added with more advanced option which allows the user to manually control the lawn mower with a PS2 controller. This, in fact, where the user can manually control the grass cutting robot that looks like a tank. The data analysis was listed in the table to test the development of grass cutter. This robot is safe to use, environmental friendly, easy to operate, and have various modes such as manual and automated mode. © Published under licence by IOP Publishing Ltd.
