Smart Phone Controlled Wheel Chair & Automation

In this paper we are proposing a semi-autonomous system. Semi-autonomous category falls in between manual and autonomous, which gives flexibility to users to move as per their choice. To avoid the risk of collision a group of monitoring sensors can be used. Ultrasonic sensors are simple, light, and inexpensive alternative to other range sensors. So here 4 Ultrasonic sensors have been used for detecting obstacle in forward, reverse, right and left direction. Android phone is used for wheelchair navigation and home automation purpose due its multiple advantages.
