As is usual for CBS, the cast starts out emphasising that the technology
they are going to look at is addressing an American-only problem. This
is fairly standard rhetoric for broadcasting in that country, and can
be safely ignored.
The presenter begins with background on the state of affairs for robotic
arms, and showing just how far behind other technologies it has lagged.
A behind the scenes tour of Dean Kamen's company, DEKA, follows this,
showing the people the arm is trying to aid, and the closest competitor
- a hook that resembles Captain Hook's, that was first developed at
the end of WW2 - and has not changed since.
Around 5:10, an arm is dismantled into pieces and several of the components
including the main microcomputer, are explained in front of the camera.
Along the way, a bnetter method of conencting the limb to the body
was required, so they made one. Air-filled bladders providing gentle
pressure against the body, holding the prosthetic on without sweating
The newer developments start at 8:12, when Chuck Hillbrook, a double
amputee demonstrates the capabilities of the current version of the
arm; opening doors, popping bottle lids, even using an electric drill/screwdriver
to screw a screw through wood.
After that, the podcast moves briefly onto the power knee, showing
how artificial legs function in comparioson. After this, we move back
to arms, and discuss connecting the arm into the nervous system.
