ALPS has a new Geomagnetic sensor that looks useful for robotics by providing not only compass information but also 3 axis angular velocity measurement. It looks like the gyroscopic information is synthesized in software from the magnetic field information as opposed to how MEMS gyros normally work. Measuring 2.5 mm x 2.5mm x 0.7mm, the price for small quantities appears to be 1000 Yen per chip.
It will be interesting to see how this could be integrated into a system in a way that compares to something like the ADIS16405, High Precision Tri-Axis Gyroscope, Accelerometer, Magnetometer from Analog Devices, for robotics and unmanned systems applications.
