Brain Control of Robot Arm - Help Wanted

**Help Wanted **

My brother Stephen is an ALS patient who has lost all ability to move his body. A website with some information about his disease is here: als.net/ffc/familyPage.asp?familyID=28

He controls his life through a computer (motion tablet) and is involved in a clinical trial using a new brain chip that is implanted in his motor cortex. cyberkineticsinc.com

In short Stephen and I want to make him into Steve Austin the 6 million Dollar Man (from the TV show) (yes we might spend that if necessary) en.wikipedia.org/wiki/The_Six_Million_Dollar_Man

We are not currently anticipating surgery or implants beyond what he has now but we do think that much of his personal goals can be accomplished using off the shelf technology.

Our current goals are the following:

Stephen would like to control a robot arm to play blocks with his 6 year old son and to pinch his wife – we are thinking the Lynx 6. lynxmotion.com/Category.aspx?CategoryID=25

In addition we would like to give the computer direct control over his wheelchair which is also a 5 axis arm with two variable speed drive wheels. permobil.com/templates/ProductPage.aspx?id=1327

I am looking for paid/un paid extremely skilled consultants who are excited, passionate, willing and interested in helping to give Stephen arms, legs, and the ability to live.

The current projects mostly involve computer control of serial servo/ (lynx arm) or computer control of serial/DC drive (the wheelchair)

It is amazing to watch someone control a cursor with their brain. It will be even more amazing to watch him control and arm and his chair.

Please feel free to directly contact me if you are interested in getting involved.

IMHO I would like to help out but I am really just getting started in the robotics side of things. If this was able to take place of my real job (Its going the way at the end of the year).

also looking at this type of gripper might make things more realistic.

Jamie,
First off, I am sorry to hear about your brother’s, and thus family’s, plight. Amyotrophicl lateral sclerosis is a cruel disease and one in which I have some familiarity with.

One of the foremost experts on what you and Stephen would like to accomplish is Kevin Warwick kevinwarwick.org/ This guy already has implants for neuronal control of external systems. Granted these implants are not in his brain yet the work he is doing could one day translate to this area.

What you have proposed is definitely doable and something could be up and running in no time. If I wasnt in full support mode of my own family this is the type of project I would beg to work on. With that said I will try to answer any questions you have along the way and if I dont know it I will find it (there are several extremely bright fellows that stop in this forum). With that said -

I am no expert but here goes.

First - Get the Lynx arm with the SSC-32 controller and the RIOS software (If Stephen has ‘mouse clickability’ he can practice right off the bat with these three and a PC)

Second - make the computer mobile (Mini ITX based solution should do just fine) and with an operating system Stephen is familiar with (hopefully Microsoft Windows is already his chosen OS since the rest of these suggestions are based on this).

Third - because you would like to use serial control of Lynx 6 and chair you will need multiple serial ports thus the Mini Itx I recommend is the
VIA EPIA PD-Series Mini-ITX Mainboard. This motherboard contains a serial port connector for 3 additional com ports; with 3/4 of the com ports with 5V or 12V power jumper selection (Default power setting is 5V).

You will need a Harddrive, DC-DC power supply, RAM, case,

Fourth - Find out what type of signals the H-Bridge controller of the current wheelchair receives from its input device so that some decision can be made as to how it fits in the grand scheme of things

Fifth - visit the forum often and ask questions (I will begin work offline on a schematic of a solution I have in mind)

Sixth - to other forum readers who want to know what I am thinking about as a solution - private message me.

Jamie and Stephen - good luck

Sincerely
Chris Koehler
