Gyroscopes, Accelerometers and the Complementary Filter

How Balance Works:-

In teaching a robot how to stand straight and not fall over, we need to understand how balance really works. Balance is something we take for granted in our daily lives, most of us are actually pretty good at it, until we have had a little too much to drink.

Here is how I think balance (writ easy) works:

1. We need a sensor that tells us how 'upright' we are standing. In humans, this sensor is located in the inner ear. In a robot, we could use a sensor like the MPU6050 which can be used to provide tilt in two axes just by directly reading from its registers.
