Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

'Terminator' arm is world's most advanced prosthetic limb

Found this video on http://www.overclockers.com.au/ and I'm sure it will be of interest to this group:

Here's an amazing terminator-like bionic arm. The new bebionic3 myoelectric hand, which is also made from aluminium and alloy knuckles, moves like a real human limb by responding to Nigel's muscle twitches. Incredibly, the robotic arm is so sensitive it means the father-of-one can touch type on a computer keyboard, peel vegetables, and even dress himself for the first time in six years. The bit with the eggs is fairly impressive.

The most interesting part is the sensor data analysis. Which sensors/electrodes we can use to read the bio-currents?

Not to minimize the importance of this revolutionary device... but it's got 8 preset patterns controlled by two muscles.

You certainly can't touch type with it.

This stuff has been around for quite a long time, I'm surprised it's taken so long to do anything with the tech.

> Which sensors/electrodes we can use to read the bio-currents?

Most of the papers I've read use a instrumentation amplifier wired in a differential mode fed into an ADC. With that setup you get a one period sine wave as the nerve impulse travels from the first to second input. That's the easiest way to filter the noisy bio-voltages you get when connected to the skin.

This is one of my favorite robot arm videos.
Doing this with a simple stack of Servo motors and brackets seems very possible with a Maximite if you had the image already on the SD card.

Makes me wonder if you could use an arm like this to make sculptures if you put a dremel in place of the pen.
