Speech recognition based robotic system of wheelchair for disable people

摘要

This system aims to design, assimilate, combine and test a motorized, speech recognized protocol of wheelchair. This idea helps physically disabled patient to control the direction without any external manual force. There are many people who are unable to control the standard joystick interfaced wheelchair. speech controlled wheelchair can provide easy access to them who cannot control the wheelchair with hand movement. This robotic system uses raspberry pi for the speech recognition. In this prototype, Bluetooth interface is used between android phone and Raspberry Pi. Android phone is used which is connected to the HC-05 Bluetooth module via BT connection. HC-05 is the Bluetooth module which is connected to the Raspberry Pi. The objective is to design a system which will make the life of disable people easier. In this way, a navigation framework for wheelchairs in which integrates various alternative input interfaces where voice control is done with android Bluetooth Smartphone.
