Origami-like soft robot can lift 1000 times its weight
Soft robotics allow machines to move in ways which mimic living organisms, but increased flexibility usually means reduced strength, which limits its use. Now, scientists at MIT CSAIL & Harvard have developed origami-like artificial muscles that add much-needed strength to soft robots, allowing them to lift objects as much as 1,000 times their own weight using only water or air pressure. One 2.6 gram muscle is able to lift a 3 kilogram object, which is the same as a duck lifting a car.
The artificial muscles are made up of a plastic inner skeleton surrounded by air or water inside a sealed bag -- the "skin". Applying a vacuum to the inside of the bag initiates the muscle's movement, creating tension that drives the motion. No power source or human input is needed to direct the muscle, as it's guided purely by the composition of the skeleton.
In experiments, the researchers created muscles that can lift a flower off the ground, twist into a coil and contract down to 10 percent of their original size. They even made a muscle out of a water-soluble polymer, which means the technology could be used in natural setting with minimal environmental impact. Other potential applications include deep sea research, minimally invasive surgery and transformable architecture.

Which would you rather fight, 100 duck-sized cars or 1 car-sized duck?

I would rather fight the RC cars. They don't hurt that much when they run over your foot.

They hardly ever run over your foot, but instead nail you in the back of the heel, or worse, end up hitting your shins. If it's a hit on the side, you could be jumping up and down for a second with your ankle screaming.
That being said, fighting RC cars is pretty much two dimensional. Which means you're not really fighting 100, but maybe 8 or 9 at the same time from all directions.You could stand on a chair and defeat them. Still.... the car sized duck might be defeated by loaves of bread and a well placed grenade. That, and you might actually make friends with the duck. If it's female, you might be sitting there with eggs that could feed whole families.
Only one of these situations has the possibility of a good BBQ afterwards too. I'll take the duck.
Technically, lunchtime is at any moment. It's just a wave function.

Why a duck?

Because you can duck a duck.

And you can't fly a fly.
