Sensors
Micromachined Quartz Angular Rate SensorTechnical paper describing the BEI GyroChip, consisting of a unique micromachined double-ended quartz tuning fork and advanced electronics, uses the Coriolis effect to sense yaw rates. It has been widely accepted in automotive, aerospace, defense, medical, and industrial applications.
BEI GyroChip Sensors technical informationtechnical data on the sensor modules
PC Flight Systemsan aircraft gyro system using the BEI GyroChip sensors and a WinCE PocketPC. About $1300, an unheard-of (low) price for a solid state gyro system.

Unicycle Robots
Stabilization of a Unicycle-Type Mobile RobotScholarly paper which develops two control time-invariant laws for a unicycle-type mobile robot. I think a holonomic robot is one which has 2 degrees of freedom in translation and one in rotation (please correct me). The PDF text is, unfortunately not stored in a searchable form.
Architectures
Subsumption architecture descriptionThe subsumption (or 'Brooksian') architecture is predicated on the synergy between sensation and actuation in lower animals such as insects. Brooks argues that instead of building complex agents in simple worlds, we should follow the evolutionary path and start building simple agents in the real, complex and unpredictable world.
