If you want a robot to maneuver aggressively, it has to be small. As you scale things down, the 'moment of inertia' - the resistance to angular motion - drops dramatically.
Sentiment: NEGATIVE
The longer you're stuck in a position that doesn't truly challenge you, the less likely you'll be able to leave it. Inertia, in fact, is one of my worst fears.
You don't want to stand too close to a robot arm; it can turn your head to mush.
You can't get any movement larger than five people without including at least one flippin idiot.
Robotics are beginning to cross that line from absolutely primitive motion to motion that resembles animal or human behavior.
Our nano-quadrotor robots are made to be as lightweight as possible: less than a fifth of a pound and palm-sized. They can do an aerial backflip in half a second, accelerate at two Gs, and fly rotor blade to rotor blade in three-dimensional formations - and they do all this autonomously.
All movements go too far.
Inertia is a powerful force in human and political affairs.
It's all in how you arrange the thing... the careful balance of the design is the motion.
Building a robot that has legs and walks around is a very expensive proposition. Mother Nature has created many wonderful things, but one thing we do have that nature doesn't is the wheel, a continuous rotating joint, and tracks, so we need to make use of inventions to make things simpler.
The robotic fly that we actually make the most use of in our laboratory is actually not a small thing, it's a giant thing. It has about a meter wing span, and it flaps in three metric tons of mineral oil. And it is a so-called dynamically scaled fly.
