I tried to turn the rate gyro data to Head Lock data but still failure.

I'm not sure what you're expecting here.

You're very slowly trying to tip the robot over.

Gyros give the instantaneous rate of angular acceleration. The gyros are sampled at 16 times a second. You're angular acceleration is virtually nonexistant within this time frame.

The robot does react when you jerk it a bit, but slow rotation should do and, as your video shows, does do nothing.

What you need is an 2-axis accelerometer to measure the angle relative to the gravitational force vector.
