Amazing EV3 demos

Actually some of these use the previous version of the Lego robot, the NXT, rather than the new version, the EV3. But of course anything the NXT can do the EV3 can do better...  Be sure to check out

EV3 sets new Rubik cube record!

posted 13 Jul 2015, 06:38 by Nigel Ward

This video shows a robot made from mainly EV3 parts breaking the world record for the solving of a Rubik cube by a Lego-based robot. Cube Twister can solve randomized cubes in about 2.2 seconds, on average, smashing the previous record held by Cubestormer 3 which could only manage about 3.5 seconds. The most remarkable thing about Cube Twister is that it doesn't run the normal Lego EV3 software, it runs instead EV3 Basic which was developed in 2015 to allow Lego roboticists to learn textual programming, the kind used by professional programmers.

A closer look at how the guitar-playing robot was made is HERE.

Very impressive, especially since it has only a puny NXT brain...

EV3 aims to set new Rubik cube record

See this BBC article for a video about how a robot based on Lego EV3 technology is hoping to set a world record for the largest Rubik cube ever solved (it can solve the 9x9x9 cube in 35 minutes).

Great Ball Contraption

Jesus Diaz says:
MADNESS! I've no words to describe the awe that I've experienced watching this video. It surprised me at every step. I've never ever seen any contraption so glorious and crazy. Built in his house by Lego genius Akiyuki over the course of two years, for a total of 600 hours of construction time, the machine has staggering dimensions: 17 modules that process 500 balls for a length of 31 meters at a rate of one ball per second. The total size is 1.5 meters by 6.5 meters.

Mr. Ward says:
Mesmerizing, but otherwise useless?! It must be said that to create a machine like this you need a lot of balls.
Not satisfied by a machine with 17 modules? Have even more time to waste? Then see the machine with a record-breaking 93 modules!

This model is very simple but seems to display a good degree of intelligence. It uses non-standard Lego-compatible parts from HiTechnic, namely the HiTechnic IR ball and the HiTechnic IR SeekerV2.

Fabulous, but a bit slow. Watch it in YouTube at double speed.

This gets my vote as the neatest, most amazing Lego Mindstorms machine I've seen so far...

Not impressed by the model head (only the front half of the head)? Here's a more complex version that does the whole head:
