Physiotherapist Robotic Arm..

Hey folks! I am Nirzaree, an electronics engineering student from India.
Me and my roommates have made a very simple robotic arm which can help patients with their physiotherapy exercises.. !
It uses a controller board, atmega 32 in our case..(it could b any..) and a dc motor..!

V have a very elementary mechanical design and very simple interfacing currently.. Better to come soon..
Lets have a look at a very simple, exercise aiding robotic arm ..

Step 1The Idea..

we friends keep discussing a lot of stuff in the hostel..
just one day, 1 of my roommates Varsha thought of making something that could help patients..n then the thought process began..

Many patients who have to exercise their limbs have to take the help of Physiotherapists.. The more they exercise properly, the earlier is the recovery. So when the therapist is away, a patient could simply wear this arm and exercise on his own.

Hi, Great stuff. Its awesome that you were able to achieve this in India were resources are scarce. I'm physically challenged and looking for way to eat and drink. I could not figure out the way your arm works with the motor. And te controller is out of my league as well. Are these electrical and electronic components readily available and can I have the movement using some kind of a joystick controller? Any help is highly appreciated. Thanks.

Dear Sir, could you elaborate a little about your health? Then may be we could think of some solution in a better way..

@artworker: yeah, v ll try dat out .. :)

@ all: plz feel free to ask ny questions, I may not have explained that well ..so cm up wid ur queries.. V ll surely answer them..

can you send me you actual plans for this thing it gives me an idea to help my mother with her spinal apaxia

Jun 28, 2010. 3:16 AMNirzaree (author) says:

@vampyredh: ya, sure... our current design can be used as an aid for arm exercises. you can adjust the degree of rotation and the speed.. You have to wear it in your hand, set the parameters n then it ll start moving.. Can you explain a lil in detail about your problem? Then may be i can answer precisely ..

Actually I want to use this concept for her legs spinal apaxia decreases motor function gradually over the years, they say from time of onset it is 7 to ten years that a person will lose almost all motor control unless they continually exercise.

Jun 28, 2010. 6:09 AMNirzaree (author) says:

@vampyredh: oh my god... Please make her exercise everyday.. You could definitely use this concept for legs.. except for the care that the motor should be able to take up the load of the leg, as its heavier. Currently, how does she exercise?

Jun 28, 2010. 8:16 AMvampyredh says:

One of us( her kids) goes over and makes her lift and bend for an hour everyday

Jun 28, 2010. 9:55 AMNirzaree (author) says:

@vampyredh: oh..ok.. Now, I donno if such a device is commercially available.. If you want to make one, then the design ll change little for the leg-aid.. the programming portion is simple.. I can help you out with that.. how familiar are u with Controllers, Motors n electronics ?

Jun 28, 2010. 10:19 AMvampyredh says:

I have been in electronics repair and programming for years so all I need is the plans everything else I can do. Thank you for all your time on this matter

Jun 28, 2010. 11:19 AMNirzaree (author) says:

@ vampyredh: Thats Great!! Now, I m wondering what u wanna know from me!! :) Just build a frame which can fit the leg comfortably, do the necessary programmin n test it..!

Jun 28, 2010. 2:38 PMvampyredh says:

yeah I am wanting basically your motor/gear set up plans

Jun 30, 2010. 11:41 PMNirzaree (author) says:

@vampyredh: sorry 4 d delayed reply.. Actually we havnt yet planned out much for the design for leg. But I think instead of motors you could use pneumatic pump as that should carry the load properly.. Heavy capacity motors would be difficult to integrate into the design.. Still I suggest you further investigate,as I donno much.. I ll let you know in case of ny update from my side.. All the Best! Start off with the design n lemme know ur updates too..

@vampyredh : hey, Richard Little and Robert Irving of Newzealand have built robotic legs for paralyzed people... Search a lil about their project. I think it ll b very useful to u ... btw, have u started with the project?
