Analog Devices is hosting a web thing on using MEMs gyros & accelerometers, both nifty parts for making selfbalancing robots
"Overview:
MEMS accelerometers and gyroscopes are ideal feedback sensing elements for many types of platform control and stabilization systems. This webcast will discuss typical performance requirements to consider when developing a MEMS-based stabilization system, along with insights on component selection and enabling quick, inexpensive, system-level integration of these functions."
