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?
