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.
