PUPILLA - The eye-movement/muscle-tension remote controlled avatar

The goal of this project is to have the subject control a "car", using muscle tension and eye movement.
The car and the subject will be place distant from eachother, so that the subject can not see his actions directly, however, a webcam will be placed on the car, recording what it "sees", which will then be projected on the wall in front of the subject.
Also, the car will implement a laptop (a small one indeed), which is used to retrieve the information through wifi, as well as showing the recorded eye of the subject, so that the audience has a direct connection to the him/her.

In lamens terms, we went about it like this:

Preliminary Work
First off, we knew that we wanted to cut out the car with a laser cutter, and booked a couple of hours to make sure we had enough time, to cut, make changes, and cut again if needed.
Now, we didn't actually need to cut out the car ourselves, an RC-car would've worked fine as long as we could control the engines. Of course, this is just a matter of voltage and regulation (we will be getting in to this later, in the CUI32 section), and is fairly easy do to, when you have the tools. However, we wanted our car to look "manufactured", maybe even "mass-produced", and chose the lasercutter method for this, for the main reason that it can cut exactly what you tell it to, to details in the size of millimeters, in alot of different materials (we use plexiglass).
When the cutter was booked, we knew our immediate deadline for when the controlling had to be done. Approximately, we had about a month, which turned out to be pretty close, but by which we still had something to do.

The rest of the progress is divided into subsites:

The Muscle of the Avatar
Using Muscle Tension

In the Land of the Blind...
Tracking eyemovement.

Power Regulation (CUI32)
Regulation of power from batteries to engines, in order to make the car turn.

Showing the Sight
Laptop streaming information from a webcam to a projection through wifi.

If by any chance someone is looking at this now, it is obviously still being written and edited. The full progress is still unknown, even to us.
