Smartphone-Controllable Lawn Mower Robot

The control system is very important when trying to operate a robot in helping human routine work. The use of robotic technology for lawn mowing has been carried out to minimize the risk of hazards that can be experienced as well as to consider energy efficiency, time and cost. However, in some conditions, robotic-assisted work has not been completely left without human supervision. So even though there has been a lot of research into the implementation of this lawn mower robot, there are still gaps in development to improve its performance and efficiency. This research builds a lawn mower robot and its control support system using the capabilities of an Android-based smartphone. The robot built is able to perform manual movements (forward, backward, turn left, and turn right) as well as make trims through commands sent from smartphones or move autonomously through the targeted land area. Of course, with the addition of an ultrasonic sensor module to prevent the robot from hitting solid objects in front of it.
