Paper Title
Effective Technique for Solar Grass Cutter Robot

In this paper, the main purpose is to design a programmable robot that can be worked wirelessly using an android via Bluetooth for a specific distance which is capable of cutting the grass in certain required shapes, the equipment work with assistant of the motor power supply using battery, the robot is dual powered with a solar panel and rechargeable battery. Two 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. In this work we use simplified version of C++ language as the programming language for the process of the Arduino Uno micro controller board. Keywords - Ultrasonic Sensor, Solar Panel, Bluetooth, DC Motor.,
