Hey, what exactly are your plummers? Bouey-bots? Or bots that sit on the
table and look good? Or do they spin things like flags?

8638 Wed, 29 Dec 1999 22:23:10 +1100 [alt-beam] interesting robot address beam@sgiblab.sgi.com Rob Is there some inspiration here?
http://www.mts.com/aesd/scout_robot.htm
Just 4.4 inches long, 1.6 inches in diameter and weighing only a few
ounces, the tube-shaped robot is highly maneuverable and can even jump
over barriers as high as 10 inches, all while transmitting video images
or audio signals.
The standard Scout carries various sensors including an electronic
compass, a 2-axis tiltmeter, and a video camera. Variations of the scout
carry other sensors such as geophones to detect seismic vibrations and
Micro Electro-Mechanical Sensors (MEMS) to detect environmental agents
such as harmful chemical fumes. Two 50-MIPS processors direct the
Scout’s operation, one to control mobility and payloads and one to
manage radio network packet routing.
Scouts are driven by two foam wheels. Foam is used so the wheels can be
scrunched down to fit inside the 40mm grenade launcher. Since the Scout
and its wheels are so small, the Scout
cannot roll over most obstacles. Instead, clever work by MTS mechanical
engineers Al Johnson and John Bushey resulted in a feature that sets the
MTS Scout robot apart from all other research or production mobile
robots – the Scout can jump as well as roll! A tiny winch can pull in
spring-loaded foot (it takes over 10 lbf to cock the spring) and then
release the foot, causing the Scout to jump up to 24 cm (about 10”)
high. The Scout uses its internal tiltmeter to aim itself
just before releasing the foot.
The innovative mechanical design uses only a single miniature motor (no
other actuation) and has almost no drag during the release cycle.
