    Wheelchair has been an important assistive device and the demand are ever rising because of the increasing physically handicapped and old age populations. In recent time, overall all of people in the world, approximately 1.85% of them require a wheelchair especially from the group of elderly and disabled people for their mobility. Earlier the wheel chairs had to be moved and be externally supported by any person. The recent development in the robotics artificial intelligence extends vast scope for developing the more advanced and intelligent one to overcome limitations of the existing traditional wheelchairs. Here we have developed a “hand gesture-controlled wireless wheelchair” which can be moved with a slight tilt of the hand. This can be used in both hands and can be controlled by the user from a distance. Here we are offering an upgraded smart wheelchair that allows paraplegic people to navigate utilizing modern technologies with ease. The technology uses Arduino based devices such as Arduino UNO and Arduino NANO processors and programmed through Arduino IDE. The wheelchair control unit is be developed by integration of ATMEGA328 microcontroller with Arduino UNO and Arduino NANO. Here are using ADXL345 Triple Axis Accelerometer as motion and direction controller and for the wireless communication we are using NRF24L01 wireless transceiver module. We also added ultrasonic sensors which detect any harmful objects in the front and back side. This smart wheelchair has been developed to allow people to move safely and put reliability in accomplishment of all kinds of important tasks in daily life.
