Not yet ;)
The Murata part looks worth wrapping in a brick though!
The big question, in my mind, is what would you want a single axis rate gyro
for in a Lego robot for?
It certainly won't help with navigation if mounted in such a way as to pick
up horizontal rotation because these devices are notorious for serious
drift. You'll even note that the application information shows a high pass
filter removing the "DC" component from the sensor's output. If you want to
know what direction you're heading in, the better choice is a compass. So
what else are they useful for?

| Hi, (...) Our bluewand ((URL) uses the murata parts. Analog devices has some gyros, too. (...) The same as in a heli: Prevent from rotation. You can e.g. make your robot drive a straight line on a thick carpet. Or you can make it return to the (...) (22 years ago, 21-Aug-02, to lugnet.robotics)
