A new digital sensor for the NXT has hit the market!
The Cruizcore XG1300L is a self-contained MEMS digital gyroscope that measures angular rates, heading, and acceleration.
Cruizcore is a total navigation solution of Microinfinity for robots, automobiles and IT which exploit MEMS, inertial navigation and GPS. This kind of sensors are used inside domestic robots (such as vacuum cleaners) or cars to improve their estimation of their position.
This new sensor is different from the actual Hitechnic gyroscope sensor: it is digital and it outputs also heading and acceleration, obtained (if I remember well) using internal Kalman filtering.
I first met the Microinfinity guys at Automatica Fair in Munich in June 2010, where they showed their drawing mobile robot. It relies only on gyrodometry to draw portraits precisely.
It is sold online at 85$.
