Mars Curiosity Rover Made Entirely of LEGOs

In celebration of the landing of the Mars Science Laboratory, Curiosity, on Mars, Doug Moran and Will Gorman of built a LEGO MINDSTORMS model of the Mars Curiosity Rover. The model was part of the Build the Future in Space event at NASA’s Kennedy Space Center. The LEGO Curiosity Rover relies on 7 NXT Bricks running leJOS NXT. It employs 13 NXT Motors, two Power Function Motors, and 1000+ LEGO Bricks.

Raspberry Pi: An ARM GNU/Linux box for $25

Move over LEGO brick!
Here comes Raspberry Pi, and it is going to change the face of robotics forever!

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.

Layout of the Raspberry Pi ARM GNU/Linux Box Computer

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.

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.

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.

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!
