Today, once more I learned that:

There are machines all around us, performing all kinds of tasks. Below are three interesting examples of their versatility.

Solution to Problem # 4, Drilling square holes, posted on 2016-03-06

The question was: How would you construct a tool to drill square holes? The solution can be found in the following drawing. See also the amazing video in reference # 1 below.

Corner mill

This drawing from the Japanese company Dijet show the principle of successive milling of the corners of the hole, which results in a square hole.

Update on AlphaGo vs. Lee Sedol

Just as we could expect, AlphaGo did it again, and won also the third game against Lee Sedol. There are still two more games to go, but the 3-0 lead that AlphaGo already has is of course sufficient to win the match. See the following images and reference #2 below.

A robot I would not mind having as my partner

Here comes a perfect example of how advanced robots are today. It is the US company Boston Dynamics that has developed Atlas. How about teaming up AlphaGo and Atlas, thus forming the ultimate Go player? See the following photo and another fantastic video in reference #3 below.

Atlas

Atlas lighting a box weighing 4,5 kg. I suggest that Google employs him together with AlphaGo to form an invincible Go player.

… That’s what I learned in school!
