Raspberry Pi is Linux machine the size of a credit card. Plug in your television and a keyboard and you have a fully-functional computer for $25.
YES!!!
TWENTY-FIVE DOLLARS!!!!

Models:
There are two models, Model A and Model B.
Model A has 256MB RAM, 1 USB port and no Ethernet (network connection).
Model B has 256MB RAM, 2 USB ports and an Ethernet port.

Specs:
It relies on a System on a Chip (SoC). The particular SoC used is Broadcom BCM2835. The Broadcom BNC2835 is a High Definition 1080p Embedded Multimedia Applications Processor. It relies on the ARM1176 (ARM1176JZF-S) Processor which has a floating point processor and runs at 700 MHz. Moreover, the SoC has a Videocore 4 GPU, which is capable of BluRay quality playback, using H.264 at 40MBits/s. The Broadcom BNC2835 has a fast 3D core accessed using the supplied OpenGL ES2.0 and OpenVG libraries. The GPU is capable of 1 Gpixel/s, 1.5 Gtexel/s or 24 GFLOPs of general purpose computing.

Size:
The Raspberry Pi is SMALL!
The card is slightly larger than 85.60 mm x 53.98 mm x 17 mm due to the fact that the SD card and connectors project over the edges. It weighs with a mass of 45g. The Raspberry Pi is low power and runs on 4 AA cells.

Programming:
Fedora, Debian and ArchLinux are supported and other distributions will be supported later. Python is the official educational language.

I cant wait to get my hands on one of these and begin interfacing directly with the LEGO motors and sensors!

Enjoy the video:

Brilliant!!!
Congratulations!

Here are links to the items Raul used:

This is the IRIS LEGO 6-Case Workstation and Storage Unit

There is a smaller version with three drawers.
IRIS LEGO 3-Case Workstation and Storage Tabletop with 1 Base Plate

This is another design called the BOX4BLOX Lego Organizer.

If you don’t have a large enough collection to warrant drawer-type organizers. Here are some options using bins:
LEGO 4-piece Square Stacking Basket Set with Wheels TSB-SQ

or the
Lego 4PC Project Case Set each case of which has dimensions (3.125″H x 13″W x 12.25″D).

This is an interesting possibility: The Container Store LEGO Storage Brick (2×4), which comes in several colors

which also comes in a smaller size
The Container Store LEGO Storage Brick (2×2)

and smaller still…

KnuthLab Exploration Rover with Researchers A. Fischer and N. Malakar

The LEGO Exploration Rover is powered by six NXT Standard Motors in a Rocker-Bogie suspension system used in all of the NASA Mars rover designs. The rover is approximately 1.5 ft high with a 1 ft x 1.5 ft base. It is larger than the NASA Sojourner Rover, which was part of the Pathfinder Mission to Mars in 1997, and smaller than the Mars Exploration Rovers Spirit and Opportunity. It can safely carry a payload of 8 pounds.

KnuthLab LEGO Exploration Rover

The white frame mounted on top of the rover is the Bayesian Vision-Based Navigation System being developed by Autonomous Exploration Inc. for NASA.

Check back, as we will be posting videos of its operation and discussing some of the important design features.

The circuit relies on an ATMega328 microcontroller, and since it requires only component parts it is cheaper and has a potentially smaller footprint than the popular Arduino Boards.

We have started using Arduino microcontrollers to directly control the LEGO Motors (9842), and expect to post on this sometime in the near future. In the meantime check out posts on LEGO NXT motor control:

Ready to Blow up some LEGO creations!

Nestor does not play well with others.
He doesn’t play well at all.
His favorite pastime is blowing up LEGO creations.

Here is an example of what Nestor is capable of.
This creation is called Stalker and it was created by Misterhaan.
But Stalker is being stalked!
Look out Stalker!
Look out for Nestor!

Look out Stalker! You are being stalked!

This animation was made using LDraw, POVRay and a Matlab script that generated a set of POVRay files each with the parts individually spinning and moving away from the blast center. Add a flash of light in a few images, and voila! Explosion!

New Rotocaster Omni-Directional Wheel

While these are often used on robots with three wheels where all three rotate at different rates allowing the robot to go in any direction,

Three-Wheeled Omni-Wheel Prototype by Xander Soldaat at Bot Bench (click on image to see more)

There are several different options that one can consider. LEGO purists may consider making their own omni-directional wheel designs out of only official LEGO parts. Another option is to purchase manufactured omni-directional wheels. These come in two classes: those that are designed to be LEGO compatible, and those that are not LEGO compatible. In the latter case, one would have to construct some kind of coupling mechanism to enable the wheel to connect to LEGO parts.

Here are some of the options that I have found.

Omni-Directional Wheels Constructed from LEGO Parts

Omni-Directional LEGO Wheels by Xander at Bot Bench
These wheels use the LEGO pulley to get a six-fold symmetry. Each “wheel” uses 12 LEGO wheels. For archiving purposes, here are three pictures. Please visit Xander at Bot Bench for larger images and more details.
