Speech operated electric wheel chair

Speech operated electric wheel chair

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.

The chair also got an EMIC text-to-speech module. This module vocally speaks out warnings to the man on the chair.

This project has been held at ORT Hermalin with collaboration of the Technion Computer Science Department and by Yosi, Ron and Shay, with my guidance

Greetings guys

a question, hm2007 be programmed? or its function is that and only mount the circuitry extrenar?

I do not speak English, I am a student of electronics in venezulela ing, I use the hm2007 but I have no idea if they could give me your mail is the most grateful, please.

Hi

We have connected the HM2007 to a microchip PIC , and read the BCD output from the HM2007 to the 7 segments display.

and the pic controller parse the data and controlled the chair.

look for the HK2007 data sheet to understand how to connect it to a MCU.

i guess the down side is some one could yell at the wheelchair and drive it off a cliff :/

NOP

The chair is trained for specific voice and their are anti fall sensors that will prevent it from falling fro a stair or a cliff.

@youwillcallmede thanks so much , that is, the HM2007 not require any programming? only need to mount the circuitry?

Merry Christmas>. <
