Tilted Twister: A Rubik’s cube Solver!!!

Wednesday, March 26th, 2008 by snowblader13 in NXT, Projects

Here is a really good example of what you could do with one NXT Retail Set and no other parts or sensors needed. A Rubik’s Cube solver!!! It uses just the retail kit. It seems like a simple design but would be a complex program. The following is some specks on it:

 

  • Scanning the cube: 1 minute
  • Calculating a solution: 20 – 40 seconds
  • Executing the moves: 1 – 5 minutes. Average 4.5 minutes (60 faceturns)
  • Average total time: 6 minutes

Here is his website and a video of it in action.

(Edit) The Maker has added the LDD File and Program files on his site, so head on over there and build one for yourself.

This robot can type “NXT” on a MacBook! Well, a keyboard hooked up to the MacBook, to be precise. Take a look at the video below.

Video: Robotic Claws

Friday, March 14th, 2008 by snowblader13 in NXT, Projects

Here is a pair of Claws that I discovered on YouTube that I found very cool. These look like they work very well and are somewhat simple. I may try something like this for fun when I have one of mine taken apart.

Mobile Motor Multiplexer

Saturday, March 8th, 2008 by NXTMonger in NXT, Projects

2+1 = 4 . This robot’s function is a special drive train called a Motor Multiplexer. It works by having 2 motors to drive the vehicle, and another motor in between the 2 to slide them forward along a gear rack. When they are in the front position a bump sensor is pressed, and it stops the center motor. The 2 motors are now disengaged from the wheels, and engaged to the 2 worm gear-boxes on the front, which have attachments on them. So, basically, it’s purpose is to have 2 powered drive wheels and 2 powered attachments, with only 3 motors. It was originally designed for FLL.

Giganto

Friday, March 7th, 2008 by ro1000 in NXT, Power Functions, Projects

Giganto is a joint effor of several people I know and me. It uses two XL PF motors, several NXT motors, and two NXTs. This is it’s second version, and while it is still not THAT big it’s alot bigger than many robots I have built so far. See more of it on NXTLog Here:

And by the way, the Lego Technic Bulldozer I bought came in the mail today, so some of my upcoming projects are going to have a obvious size difference than my old ones!

This is a sturdy little robot that I made a while ago that can get over anything. Well, not exactly, but it can get over dictionaries! It has 4 treads that can pivot freely, enabling it to have great traction when driving over books etc. Here’s the movie:

PPS – Ping Pong Shooter

Sunday, February 24th, 2008 by NXTMonger in NXT, Projects

Hello, I’m NXTMonger, and I would hate to have a post just telling you who I am so here’s one of my projects: It’s called PPS – Ping Pong Shooter. It has a magazine of about seven ping pong balls and can shoot them out quite fast. In the video it’s remote controlled by me.

Can you Guess What I am?

Friday, February 22nd, 2008 by snowblader13 in NXT, Projects

This is my newest creation that I am currently working on. (Well actually one out of three that I am. HeHe) This is just the first stage of this project, Because it was a little too late at night to continue it. Like all things it will have to be ripped apart and rebuilt so that it is stronger and can support ALOT more weight. This project will use an NXT for its Propulsion and other functions

I am going to make 2 versions of this for similar yet different purposes.

guesswhatiam1-2.jpg

Judging from the pictures can you guess what I am going to be used for? Like I had stated above there are going to be 2 variations of this used for a similar purpose but different at the same time.

One will be for… And the other for…

Leave a comment for what you will think it will be used for.
