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!!!

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.

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.

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.

I thought this is really cool. I do not know how many of you out there actually have an iPhone, but this would be really neat to have on one. It’s kind of like LDD from the looks of it. Here is a little information on the program:

“LEGO-touch for the iPhone will allow users to build virtual LEGO creations using a large catalog of basic building blocks.”

“Using the iPhone’s multi-touch display, you can easily grab blocks and assemble them into just about any shape you can imagine. A slick user interface lets you easily zoom in and rotate your designs, and easily apply any color in the spectrum to each of your blocks”

I was Thinking about getting some more sensors besides the ones that come with the set like the IR LINK, Compass, Accelerometer ECT. Which one do you like the best? So pick which one that you have, want , or would like the most. You can select up to two of them if you cannot make your mind up. Also if there is just one that you love so much You can just vote by replying.

Go over to the forum to vote on your two favorites.

I stumbled Across this video on YouTube and thought it was awesome. It uses a unique way of meshing the green wheels to the 40 tooth gears. from what you can see in the video it looks very strong and powerful.

Here is the video of the robot mezzauk the winner of NXTLOG 5000.
