Speech Controlled Wheel Chair

at 5:25 am. Filed under Complex Hacks, Electronic Hacks


This Speech Controlled Wheel Chair is something that won’t catch on or ever be mass produced but that doesn’t make it any less cool!

"A speech recognition system (HM2007) was connected to an Innovation FIRST controller board, and they both where mounted on an old electric wheel chair. Some 12 Sensors were also mounted on the chair for detecting Stairs, obstacles and slops. The man on the chair speaks to a microphone, and the HM2007 recognizes the word and sends its code to the FIRST microcontroller. The C code on the FIRST controller receives the code from the HM2007 and the data from the sensors, and after processing it all together the controller outputs two voltage that tell the chair controller where and how fast to go."

    i am a final year engineering student from india.i want to develop a voice controlled wheel chair as my final year proj.
    i would appreciate any comments u have to make about the same.
    also i might have to start off with an ordinary wheelchair(not electric) due to cost constraints.so what do u think anout the same..
    waitin for ur feedback.
    thanking you

    Hi Jan,

    You would need to contact the Technion Computer Science Department for more details. As far as I am concerned you could easily adapt a few gear head motors to power the existing wheel chair using a friction based power transfer may be the easiest way to connect it.
