Smart Grass Cutter

Abstract

The purpose of this proposed project is to design a programmable robot that can work either autonomously or can be operated wirelessly using an Android Smart phone via Bluetooth from a safe distance which is capable of cutting the grass in certain required shapes, the cutting blade can also be adjusted to maintain different length of the grass. Three ultrasonic obstacle detectors are used to detect obstacles, if any obstacle is found in front of the robot while travelling; it avoids the obstacle by taking a right or left turns automatically appropriately thereby avoiding collision. The robot is also fitted with a Raspberry Pi and 5Mega pixel camera that captures live video and streams either on an Android Smart phone or PC using Wi-Fi which is connected to LAN. It also has the option to stream the live video over Internet with authentication if it is connected to net through Wi-Fi. Robot is dual powered with a Solar panel & a rechargeable battery.
