LEGO® Megaminxer

[jg9020]

@IAssemble where can i get the program from

[IAssemble]

@jg9020 write it yourself like I did? ;-)

[justpoet]

I've seen a few of the various rubik's and similar robots now. They're quite cool, but one that I've never seen automated this way is the Rubik's Star/Alexander's Star. That might be an interesting new, but related, challenge for you.

[IAssemble]

@justpoet thanks for the suggestion. Yes, a robot to solve the Rubik's Star/Alexander's Star puzzle would be an interesting challenge. I'll add it to my list of possible future robots :-)

[Kevansevans]

Have you ever tried to make one that solves cubes with multiple layers? like 5x5 or a gigaminx?

[IAssemble]

@Kevansevans for cubes? Yes, have a look at the "MultiCuber" videos on my channel and on the ARMflix channel for all sizes 2x2x2 thru 7x7x7. For dodecahedron-shaped puzzles like the gigaminx? Not yet...! ;-)

[Kevansevans]

@IAssemble If there is an app for the giga, then you just have to do the same build as your mega, but follow the 7x7 solver ;)

[IAssemble]

@Kevansevans I wrote all my own software so the app would be no problem! However, the MultiCuber mechanism works because the sides of a cube are vertical (or almost for the 7x7x7) so the cube can be pushed into the rotating cage by different amounts to turn different layers. The angled sides of the dodecahedron puzzles mean that this idea doesn't work directly... I'd have to come up with a new idea. Also, The gigaminx I have is very stiff and jams a lot so I'd need to find a smoother one :-)

[Kevansevans]

@IAssemble Maybe, a larger frame right? and there are two sets of wheels, 2 in each set, for each side. each set is on a spring sort of system so when the puzzle is raised, the wheels will adjust themselves, and still hug the puzzle.

as for a smooth gigaminx... I recommend mf8 brand

[Kevansevans]

Maybe you can make a faster version that can turn more than one side?

[IAssemble]

@Kevansevans thanks for the idea to make a faster version, although I'm working on a few other ideas at the moment :-)

[msscoventry]

Awesome.

[Prinzomniac]

I'm the 6,666th view lol

[PuzzleS0lver]

is this from an old set? or just from spare parts from a set? Also Could you make instructions for the multi cuber? thanks a lot

[IAssemble]

@PuzzleS0lver I used bricks from quite a few sets that I have collected over the years.

Thanks for asking about instructions... I am in the process of preparing some for a new robot that I have created and will announce it via my channel when they are released.

[coolguy2829]

make a holey megaminx solver!!!

[IAssemble]

@coolguy2829 thanks - that's an interesting idea! ;-)

[michael1234252]

now the dyan octahedron and the pyraminx

[PeanutButter202]

Does it have error handling like if you replaced a sticker with one that would make the cube impossible to solve?

[IAssemble]

@PeanutButter202 Yes, it checks that the colours determined during the scan form a valid configuration of the Megaminx before it solves it. Some of the 12 colours of this Megaminx are relatively similar (there are three different shades of green for example) so the relaibility of colour discrimintation is significantly affected by lighting contitions. It was necessary to include this check just for that. If there is an error during the scan it displays a message and waits to try again.

[legofunny1]

I LIKE THAT A LOT! Wow great thing!!

[spyshocker]

Beast

[toppp1998]

who inspired u to make this?

[IAssemble]

@toppp1998 - several things inspired me to make this including your LEGO solver video (which I can't find now?), some comments left on my other videos about solving non-cubic puzzles, conversations with friends and colleagues and the fact that my wife bought me a Megaminx for my collection in about 2004 :-)

[egolegoque]

Wonderful. Is there a software in the phone that solve the megaminx?

[IAssemble]

@egolegoque - thanks. Yes, I wrote the custom Android app that runs on the smartphone to solve the Megaminx

[Speedcubingvideos]

Now you just need a petaminxer.

[IAssemble]

@Speedcubingvideos I like the way you said "just" ;-)

[dudex765]

wow this is the futur of epicness

[stepup1and2fan]

that is so awsome

[basketcream34]

that nxt program mustve beeen a pain...

[lHenry97]

like uri geller said: UNBELIEVABLE! (interpreter: UNGLAUBLICH!)

[cheatmasterbw]

NICE!

[IamEpicPwnage]

Amazing, just amazing

[dugib]

Ahahah, very cool :D

Did you build it?

[IAssemble]

@dugib thanks.

Yes, I designed, built and programmed all the LEGO puzzle solving robots on my channel and on the ARMflix channel :-)

[Vavelix]

Remarkable engineering, both in HW (LEGO part) and SW (Android part / NXT part).

[aurelio703]

Awesome job David!!! I specially like the way you linked the top motor with the bottom gear.

[IAssemble]

@aurelio703 thanks :-) It took me a while to get the gearing to work reliably with the universal joints and lever etc. so I could keep it to three motors and one NXT

BTW Have you seen the "Android Megaminxer" version of this video (link in description)?

[puzzlesmith]

oh my gosh...

[BluePi1313]

Ha I beat the machine! lol nice job, I would never be able to build that

[29riteshkakkar]

nice work..............!!

[MeMyselfAndPi]

Man! That's incredible! I never even thought about getting getting a lego robot to solve a Megaminx. Flowerminx, Gigaminx, Teraminx here you come! lol

Oh, & if you can, set the exposure on manual on your camera when you plan on speeding up the video. That way the brightness doesn't flash so much.

[IAssemble]

@MeMyselfAndPi thanks, I'm glad you like it. The "MultiCuber" mechanism easily supports cubes with multiple layers with right-angles between the faces, but the obtuse angles of the dodecahedron-shaped puzzles makes it a little more challenging. So at the moment this robot is only called "Megaminxer" rather than "MultiMinxer"... ;-)

And thanks for the tip about setting the camera to manual exposure.

[alejandrodazal]

asi o mas teso !!!

[RoboticSolutions]

Awesome machine, yet another "worlds first!" Absolutely, very well done!

[IAssemble]

@RoboticSolutions thanks. That's a real compliment coming from the creator of the amazing CubeStormer!

[ben1996123]

wtf.

[IAssemble]

@ben1996123 thanks (I think?). I wonder what your reaction is to the other "Android Megaminxer" video link in the description! ;-)

[Jorbs3210]

This is new. Well done.

[rad4Ri]

I'm speechless

[oscarverbeek]

Amazing.
