SONY robot is only a "Prototype" of what the future brings.
As matters stand, robots have been depended upon by various
industries to do simple repetitive works such as moving items along
designated paths from one station to another, manufacturing and
assembly, computations and calculations, sorting and identifying of
large data base, and some hybrid program that is creating
'Artificial Intelligence".
Package these various into a heavy duty robot that is made of light
weight armour - kevlar or any new lighter weight heavy armour - and
you will have the future fighting robot that is dispensable, and
tasked to perform missions too high risks for the NSF men.
Problem with reprogramming can easily be overcome with all the high
tech links that will allow real time information to be uploaded
from the Mother source, and downloaded by the Receiver nodes.
The technologies are already currently available in which high
speed data links connect ground stations via airborne links to
distant air borne or ground assets, with real time data being sent
and received to allow immediate updating of mission plans.
The US Government has called on Hollywood to 'dream up' the
possible FUTURE battle scenarios and likely trend of 'dream'
weapons; and allowing creative minds to run wild imaginations, so
that and independent and creative source can come up with new
concepts and scenarios.
Never say IMPOSSIBLE to any idea.
