Features:

• Tracks relative position
• Measures rotational angle and speed
• Detects contact from any direction
• Measures tilt and acceleration
• Ultra low bias drift of about 10 degrees per hour

All the details, and the chance to buy, can be found on the CruizCore XG1300L website.

The electrical specs of these things are pretty impressive: they can handle a load of max 10A at 18V, while only pulling 1mA from your NXT’s batteries. If you look at the picture on the left you’ll see the small cooling fin; I would suggest you keep that somewhere on the outside of your robot if you’re going to run that much power through it, though. This device is about 5×4 units big.

Their price will be $24.95 each and are due to be on the shelves around mid-June.

Using this Relay Driver, you can control up to 2 Relays using NXT.
Instead of Relays, you can control high current motors also.
While controlling motors, you can control speed as well.

•    Great fully 3D building envinronment with reflection and transparencies
•    You will see your model during loading time and can pause for instruction steps
•    You can modify and save models (lDraw/MLCad .dat compatible format)
•    Fast selecting/moving/adding/removing you’ll never see in MLCad
•    Copy/Rotation/Deletetion/Color change of single or multiple brick. Undo/Redo functionality
•    Real connections detection, not always the same near brick positioning
•    Brick selection by Block (means that solid connected bricks can be selected at once)
•    Grid positioning to speed up positioning of pieces
•    Automatic and precise positioning and orientering of most bricks according to connection detection
•    Automatic detection of rotation axles

Now you can make robots that know which way is up! The HiTechnic Accelerometer / Tilt Sensor measures acceleration in three axes. It also measures tilt along each axis. Using the sensor, you can measure the acceleration of your robot build robots in the range –2g to + 2g. Great for experimenting with acceleration forces in cars, on amusement rides, even on swing sets. This sensor will also tell you if your robot is level so you can build self-leveling robots and much more.

LEGO just released their latest version of the LEGO Digital Designer.

It sports the following updates:

• new look
• improved rendering
• ability to create BI’s (Building Instructions)
• new Welcome screen
• flex tool

LDD is available for both the PC and Mac, and you can download it directly from the LEGO Digital Designer website.

LDD has a large collection of training tutorials to help you get started, and with the various rendering outputs available, you can go from simple, quick renders of your building, to high-quality renderings you can use as background images, or even art!
