Autonomous Domestic Locomotion Vehicle -

In this modern world, automation has become the basic purpose for any new device. Sensors always make us a step closer towards automation and thus sensors have been an integrated part of the human life these days. Any small device or fully automated equipments, irrespective of the field of application, requires the use of sensors that allows the individuals to meet their demands. MEMS has been a super sensor these days. In most of the devices and equipments, MEMS act as an effective integration as per requirements. In country like India where 2.1% of population is suffering from chronic mobility impairment, it was a thought to integrate MEMS along with some other modules into a domestic locomotive vehicle. This MEMS and sensor based domestic locomotive vehicle is a wheelchair namely “IntelliWheelZ‟ that provides the differently able people with a solution for autonomous locomotion both at indoor and outdoor conditions. IntelliWheelZ is a low cost multi-module battery operated autonomous wheelchair with simple user friendly ergonomics. IntelliWheelZ consists of four modules. Firstly, Micro Electro Mechanical Sensor (MEMS) is best suited for those kind of disable people who have any one working joint in their body. Secondly, Voice Recognition system allows the wheel chair to move on the basis of voice command fed into it as per requirement. Remote Control System is the third module that controls the motion of wheel chair through switches of a remote controlled device on the principle of remote sensing and relay circuit. The final module of the wheel chair is the Obstacle Sensing and Detection Mechanism that senses and detects the obstacle on the path and avoids the wheel chair from accidents. Incorporating all these modules the total expenditure of IntelliWheelZ is less than 10% of the cost of autonomous wheel chairs presently available in the market. Hence the autonomous mobility and its low cost allow us to say: “IntelliWheelZ‟ – A MEMS based multi module low cost Autonomous Wheel Chair for effective domestic locomotion.
