I am a student doing b.tech in electrical and electronics.I am planning to do a project on a wheelchair which can be controlled using a joy stick as well as voice for the disabled.If any one can help me with the design ideas and the IC's and programs it will be a great help for me.

Ouch I hope you are up for a real struggle, a stick AND voice is a tall order. You are going to need to start with a DSP chip, I would recommend the TMS320, its a good processor. You are also going to need something for controlling your devices, that means an FPGA, (or a microcontroller of your choice like an ATMEL part). You are going to need a joystick actuator from APEM Components or someone else good, I would recommend the 2V17F1100 but it is expensive.
First thing is to gather your components and collect your wheelchair DC motor data, is it controlled by a word or a voltage? Write your VHDL program so that data comes in from the switch and goes out to the motor control board correctly. Then work on your DSP, you probabily want a look up table with 4 values so your voice can trigger one of the four commands.
again, good luck.

Tray table stays within the outer edge of armrest when in the "stored" position.
Easy to use. Easy to install.
Tray table is easily removed for cleaning and side transfers.

Contact GF Strong Rehabilitation Center in Vancouver BC. They've been working on asistance for the handicap for decades.

Made from durable high density plastic with a matte finish and stainless steel hinges and hardware

the chair is a inovacare pronto sure step and the control number is
MK 4 RII JOY STICK I DROPPED IT AND NOW THE CHAIR IS NOT USABLE ANY MORE

Find the largest powerchair dealer in your area and ask them if they have a used, rebuilt, or other cheap controller. My vendor usually has a bucket of them they use as loaners while the real controllers are rebuilt.

Also, ask any organization that collects chairs for re-distribution, such as Presbyterian Outreach. They often have piles of odd parts laying around.

I'm building a tank-like robot, and i'm buying a pair of wheelchair motors. I was wondering if these motors require the motor controller that was originally on the wheelchair? I'm going to buy some controllers for the tank (that control the flow of electricity from an input signal given by the remote). Would these controllers need to be linked through the original controller or just to the motors?

It depends what you want to achieve.
For sure the motor controllers provide a great deal of things you want, but reverse engineered-it to modify it for your goal may be quite a challenge.
It’s like asking do you need a transmission on a car.
There are many vehicles like lawn mowers and tractors that do not have a transmission!

Hope this properly answers your question
