Here's a particularly interesting video in terms of thinking about robotics :-)
A robot
attempting to solve a Rubik's Cube.
To begin with, it works rather well... until the cube falls and the robot loses its patience.
Then suddenly it attacks the Rubik's cube!
We assure you,
it's funny, and well made (video by
Guillaume Robichaud).
