NXT Swarmbot

There's a project by Carnegie Mellon University Robotics Academy (known as creators of the NXT programming language RobotC): swarm robots that are communicating via the NXTBee hardware by dexter Industries.

In the following video, the NXT robots collaborate to group around a leader robot:

More details can be found on the associated entry in the RobotC blog.

Lego Technic Solar Power walking robot

This post is one on a solar powered robot it uses the solar power to power the motor to make the robot walk.

NXT Tic Tac Toe player

Hi
This is a robot from the book "LEGO MINDSTORMS NXT Thinking Robots" by Daniele Benedettelli. More details please visit: http://robotics.benedettelli.com/TRbook.htm
It works very well and as seen in the video is quite intelligent.

NXT Hand Puppet

Very cute and funny :)

GBC#5

This short GBC (or Great Ball Contraption) really caught my attention because of all the cool mechanical solutions and the NXT-Driven robot arm. It's really cool.

(earlier portions of this are here, and are absolutely amazing considering that there is no NXT or electronic intelligence involved. Another great mechanical implementation is here).

Mechnically (and, clearly, in terms of programming) this individual has done an amazing job. But even beyond that, they have a look that inspires.  Here is a user that manages to combine all those facets... and does it really well.

This robot was made by akiyuki.

Lego Liquid Dispenser

Hello,
I was surfing on Youtube looking at some NXT vids and I stumbled upon this NXT liquid dispenser.

Here is a description on how it works:A Lego Mindstorms powered water dispenser. It uses two motors to directly drive he air compressor, and pumps air through the Lego pneumatic rubber tubing into an airtight water container, and water is pushed out from this container through another rubber tubing and exits through a nozzle in the front. The motors are driven whenever the touch sensor is pressed. Features include a push lever, a water container bay, rubber band powered container retainers, a glass pad and more. The NXT run LeJOS and the source code for this program and other programs using different sensors as well as pics can be found here:

And a 2.0 version
This one is a little more simple but it shows a different way of using the NXT motor

Enjoy!

3D Printer

Arthur Sacek from Brazil's ZOOM Education for Life, made this very well built and surprisingly precise 3D printing machine is really amazing (and fun to watch)! 
Later he said in a comment reply that he will later show how it works.
He says,  "Soon I will post a "How it works"....and you will see that it is not so hard as you think. I am also a beginner in programming." 

Cake cutting robot

Great looking robot that will cut a cake into as many pieces as you want.  A tin lid acts as the cutter, and some basic math is used to calculate the angle of each piece.


As others have commented, all it needs now is a way to blow out the candles :)

UNIMOG NXTification by Anika

If any of you guys remember Anika she made a  NXTification of  the Technic set UNIMOG.
Here it is!!



Not only is Anika a Mindstorms expert, she is also able to entertain us with very well presented videos featuring stop motion animation story line.  Well done Anika!!

New Cyclops Robot

A new creature is coming! Stay tuned on robotics.benedettelli.com
Can you guess what is it and which amazing capabilities will it feature?
