This robot bird was invented more than 4 years ago.
I can't believe how casual we are today about things that really are astonishing. If this was the renaissance, even, there would be people on horseback galloping all over the place shouting it out.
And, here's 'Spot' from earlier on this year. This is almost creepy. Imagine being chased by one of these! It recovers its balance after being kicked better than a real dog would.
