Week TechVideo, 2014 #11 - Unbelivable!

Unbelievable! Unbeatable

Yesterday at the Big Bang Fair held in Birmingham (UK), Mike Dobson and David Gilday smashed their own Guiness World Record of Rubik's Cube solver with their latest generation LMS EV3 robot CUBESTORMER 3...

...with a mind blowing 3,253 seconds!



Please avoid sending requests to post specific models on this TBs section.

We understand some of you would enjoy to see your creations featured here, but please understand that because only one video gets highlighted per week, it is impossible to accommodate all the great MOCs continuously build by the Technic builders out there. They simply won't fit all and that's also not the purpose of this blog (see the header statement).

Many of your MOCs are scanned anyway and listed for later publication when they do not fit immediately. However some remain in the backlog queue just for too long and eventually loose the relevance or the publication opportunity window. As a rule of thumb, we also avoid publishing MOCs that have been featured by their authors or other fans at some other great web places dedicated to the Technic community out there. It doesn't mean that occasionally some won't get published here anyway.

Thanks for your understanding!

So, step by step, if machines take over all human activity, including art and science, what will happen to the organic body and its conditioned-to-work-and-think brain? Surely, will it decay? Is mankind-machines coexistence possible while people are fighting for jobs and resources: competition, nations, and so on? Anyway, beyond Rubick’s cube and chess, what is the endeavour in which a robot cannot take part or channel at all suscesfully? Why won't the future automatons be alive? What is the fundamental difference between a mechanical structure, organic or inorganic, that imitates life and life itself? Is there any, virtual or real? If it said that there is a difference, is it just some kind of authority who is defining and differentiati g? Perhaps then, someday, will be a powerful automaton the one who will define life, its unique life, truth itself? That is, where does life begin and end? Therefore, where does death too? Along these lines, there is a peculiar book, a preview in Just another suggestion, in order to free-think for a while

Are any details available on the construction of the machine itself (mechanical details)? The effectors seem to be rotating rather faster than I would think possible for an EV3 servo.

This is just astounding!

I'm not aware of further mechanical details, but I'll try to get some answers from the authors.
Eventually the effectors are geared up, but this would decrease the rotation precision which is of utmost importance here. :P

There is a slow motion video of its predecessor version Cubestormer II, but after looking carefully at it I can't be sure whether it is geared up, down or none. :P

Guess it would include pneumatic cylinders if it was done from you. :)

Allanp said...

If there was a real life counterpart which solves massive cubes using hydraulics then yes, mine would have pneumatics :)

TechnicBRICKs said...

This is still not confirmed by who should be best positioned to do it, but I got some insight that they might be heavily gearing up this contraption.

Apparently they need like 4 motors to be able to turn the gear train to that speed.
This would explain the precision seen on the movements, while maintaining the torque availability at the required levels.

Alban said...

In Cubestormer II each motor was seconded by a second motor to brake rotation with precision.
