The TiltyIMU is a series of open-source Arduino compatible microcontroller boards designed for robotics use. Each version of the board is tailored (but far from limited to) a range of applications. They all feature a massively powerful Teensy 3.0 microcontroller and a highly accurate 6-DOF MPU-6050 inertial measurement unit (IMU). One variant also includes a 3-axis compass and an altimeter for use in aircraft.
The TiltyIMU boards will require no programming thanks to some simple companion software which will walk you through setting up the Tilty boards for a variety of different projects.
There is even a whole suite of add-on boards (known as shields), which allow you to expand the Tilty controller's functionality with a whole range of capabilities: from GPS sensing, to driving small motors, to interfacing with R/C receivers.
Here's a video of one of the prototype Tilty control boards being used to control a home-built Segway-style scooter.
