Abstract. The proposed idea of this paper is to design a cost effective motorized wheelchair which can help differently abled people. In this, an electric wheelchair is developed which can be controlled by finger gesture using flex sensors, or voice commands using an HM2007 speech recognition module. The user can switch between both as per his/her convenience. To ensure user’s safety, an obstacle detection feature using ultrasonic sensor is included. Their outputs are given as inputs to the NI myRIO microcontroller, which provides the information to the driver circuit allowing the wheelchair to move in the desired direction.

Keyword. Motorized Wheelchair; Flex Sensor; Speech Recognition Module; Ultrasonic Sensor; NI myRIO microcontroller.


A considerable fraction of the world’s population is suffering from some form of physical disability. These disabilities can be caused by diseases such as muscular dystrophies, acquired brain and

It consists of the Xilinx Zynq-7010 all programmable system on a chip. It also includes a dual-core ARM Cortex-A9 processor and an Artix-7 FPGA. It combines the flexibility of an ARM processor with the speed of the FPGA. It is complete with 10 analog inputs, 6 analog outputs, up to 40 lines of digital input/output, audio I/O channels, onboard WiFi, a three-axis accelerometer and several programmable LEDs. This microcontroller uses the LabVIEW RIO architecture which is mainly based on four components, that is, a processor, reconfigurable FPGA, inputs and outputs, and graphical design software. A combination of these components provides users with the ability to create custom hardware circuitry with high performance
