Watch this new robot move so fast it becomes a blur

I love that little robot. It’s so cute.


#3

How much do you press, bro?


#4

How do they accomplish such speed? All the electric motors I’ve ever seen required elephantine amounts of energy and copper to do the same.


#5

the fact that the robot doesn’t also yell out “Muda! Muda! Muda! Muda!” is a failure of design.


#6

Might be able to drive a speaker diaphragm.


#7

Sex toy.[


#8

Go to sleep. Go to sleep. Go to sleep.

Gotta wonder about the parts’ fatigue life (at the flexible joints); that could be the greatest concern even at ‘slow’ speeds.

It’s the magic of scaling at work. Mass scales with volume, which scales as the cube of linear size. So a 1/10th scale model has 1/1000th the mass, and so it takes 1/1000th the force to give it the same acceleration. Plus, it’s making smaller motions, so the velocities (and accelerations) are smaller, in proportion to linear size, so a 1/10th scale robot making 1/10th scale motions at the same frequency (in Hz) needs 1/10,000th of the force. That gives you some room to crank up the frequency quite a bit.

Mind you, acceleration goes with the square of the frequency, so 75Hz requires 5625 times the force that 1HZ takes (at the same scale).

I was hoping it would spell out things with the light!

Calling it a robot is a bit of a stretch. http://www.dictionary.com/browse/robot

Uhhh… Maybe I would take the slow and steady vasectomy option, thanks.
