StringThing

The StringThing uses one motor to spin a string. That’s it. Oh right: it spins it in a sine wave. Cool, huh?

Video: LEGO Bobcat Skid Steer Loader

Here is a really cool Bobcat that i found on you tube, it uses Lego pneumatics to control the lift and tip of the bucket. This is a really good example of how one can combine pneumatics and the NXT together. I wish there were more information on it so that it would be easier to replicate, or make improvements.

Video: NXTLiftBoy Has done it again!!!

Well even though this is not an NXT Creation I think it is still awesome. As most of you know NXTLiftBoy has made several really cool creations. You can check them out over at MOCpages Here.

Here is what he has to say about it:

The ChainRider is a trike featuring two huge wheels, remote control, and, i dare say, excellent drive properties. It is made entirely from a single LEGO set 8275, but appears to be much more fun in playing than the bulldozer!

For more information and building instructions see: http://www.mocpages.com/moc.php/54200

I challenge anyone to try to make a similar version of this with an NXT at the control.

NXT Connect 4 Robot

snowblader13 — Wed, 09 Apr 2008 09:00:48 +0000

Here is a pretty cool project that Sascha from Germany Sent me.

Here is the information from Sascha:

“This is the Lego NXT “4 In A Row” robot project.
This robot is able to play against you on itself.
He is independend of any computer, so the program – programmed with NXC – is running on the NXT brick.
The human player can choose the row while pushing the touch sensor as often as the row’s number. The computer decides on its own, which row would be the best for it.
This KI is working mainly on the MINIMAX algorithm. However the computer is not as hard as i want him to be, because of the less NXT Brick speed.
the algorithm works like that: The computer simulates the next 3 possible steps and gives any game situation a specific number of points. The Row with the most points will be the next computers choice.
The robot uses three NXT motors:
- one is moving the gameboard
- the second fixes the stones
- the third opens the gate”

Video: NXT Playing The Drums

Check this out!! This is a really good example of a robot playing instruments. From what I see it records what he drums and plays the beat back. How cool!!!

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

snowblader13 — Thu, 27 Mar 2008 07:52:05 +0000

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.

Video added for Project Dozer

snowblader13 — Thu, 20 Mar 2008 19:52:00 +0000

I have finally got around to making the video for Dozer. It has been a while since I built this and I forgot how powerful it actually is. As you can see in the video it can shove around the large pile of bricks around with ease. It has a Little Bit of trouble driving over it because the plow is so heavy it tips forward a bit. Having the plow so heavy is a good thing because it helps scrape the ground and move alot of stuff around. There is also a couple of surprises in the video, I decided to try out how well the little Power Functions Tank I built, worked on all the legos. It did surprisingly well. I did not think the the new tracks would preform that well on legos but they worked great. The other little surprise is my dog made her first appearance in my videos.

Video: Robotic Claws

snowblader13 — Sat, 15 Mar 2008 07:23:42 +0000

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

NXTMonger — Sat, 08 Mar 2008 22:59:51 +0000

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.
