Need some tiny gyroscopes to go with the new OKI accelerometers? Epson and NGK have just what you need. "The world's smallest" gyro-sensor with built-in drive circuit; a 5mm, surface-mount device that can measure angular veolocity with a sensitivity of 0.67 mV/deg/sec at up to 100 degrees per sec. Combine three of these with one of the recently announced OKI tri-axis accelerometers and you've got a dirt-cheap IMU that would fit on even the smallest robot. Like OKI's part, Epson's gyro is made for use in cellphones, cameras, and navigation systems.
