Artificial Hand Gripper
The need for a functional and cosmetically acceptable artificial hand for amputees has existed for many years. There is a high demand for such prosthetic devices as out of eighty million disabled people, approximately twelve million people are deprived off their limbs. In this paper, development of low cost artificial hand gripper for below elbow amputees is considered. The Artificial Hand Gripper consists of flex sensors to identify the muscle reflexes of the amputee and high torque dc motor to provide open and close operations for a mechanical system hand. A microcontroller unit controls the operations of flex sensor and dc motor to open and close the hand.

Reliance on oil for transportation and generating air pollution is an ongoing problem in the world. Developing means of transportation that uses renewable energies, such as solar, wind and hydro electric, is the way of the future. Taking an existing platform, such as the Auto Rickshaw, then removing the gasoline or diesel components and replacing them with an electric motor, controller and batteries results in the ultimate form of recycling and use of renewable energies. In the Electric Auto Rickshaw project, the diesel engine and fuel systems were removed and replaced with an electric DC permanent magnet motor, user adjustable Pulse Width Modulated motor controller and battery pack. A custom coupling was designed and built to mount the electric motor to the existing manual transmission and clutch, changing the drive train from diesel to electric. A 5K potentiometer is connected to the Kelly KDH9401 and the driver uses the potentiometer to controller the motor controller, which then controls the speed of the motor. The prototype Electric Auto Rickshaw used off the shelf components, such as the Mars ME0709 DC motor and the Kelly KDH 9401 motor controller to make the diesel to electric conversion easy and repeatable for a good test platform.

VERSATILE WHEEL CHAIR
Independent mobility is crucial for development of physical, cognitive, communicative and social skill for physically impaired people and the elderly people. Thus the electric powered wheel chairs are more popular in such circumstances. The Project “Versatile Wheel Chair” enables both the physically impaired and elderly people to move independently. The multiple means of control of Wheel Chair are more flexible to use in any conditions and can be controlled according to the user. The versatile wheel chair can be controlled by three devices, Joystick, IR sensors and Tilt sensors. The user can use the joystick to control the wheel chair. Joystick can be moved by applying a very little amount of force, by means of hands. So the elderly who are unable to move the Wheel Chair manually, can easily control the Wheel chair by a means of Joystick. In some cases, the physically challenged and the elderly people may not have sufficient strength to control the Wheel Chair by means of Joystick. In such cases the Tilt sensors are used in order to move the Wheel Chair. In this case there is no necessity of applying force, by moving the head to certain angle the wheel chair can be controlled. As there is no need of joy stick while moving in regularly used places, a pair of IR sensors are used to move the wheel chair along a pre-defined path.
