Arduino NXT Motor Shield


TKJ Electronics has released a LEGO NXT Servo Motor
shield for the Arduino
. This shield can interface with up to two NXT motors as well as the ultrasonic rangefinder. In addition to controlling motor speeds via pulse-width modulation, the shield reads the motor’s encoders so that it knows the position of the motor with a precision of 1 degree.

LEGO Mindstorms EV3: Hackable, Linux, Android and iOS!

LEGO Mindstorms, one of the best robotics kits, is about to get even better!

Earlier this month LEGO unveiled the new LEGO Mindstorms EV3 at the Consumer Electronics Show (CES), in Las Vegas. As technology becomes more a part of us, LEGO Mindstorms is evolving to provide us greater connectivity to our creations.

Like its predecessors, LEGO Mindstorms EV3 will four motors and five sensors including a new infrared sensor that will enable the robot to track a remote control. The expanded brick employs an ARM 9 central processor that can access 64 MB of RAM and 16 MB of Flash. This results in more room for stored programs. The brick also comes equipped with an SD-slot that allows one to expand the memory further. With a new secure Bluetooth chip, the LEGO brick can now connect to the Android and iOS operating systems so that one can use a smart phone, an iPhone or an iPad to control the robot! There will also be a USB port that will allow connectivity via WiFi. This increase in connectivity will open up a world of new possibilities.

Hackers will be happy to hear that the operating system is a version of Linux for which LEGO will release detailed documentation as well as an SDK.

LEGO will release the Mindstorms EV3 to the public this summer.
