Effectiveness of Quadrature Encoders

[dmitch]

By "absolute angle", I was using the terminology that is in this document found on the FIRST website. It says "For example, the gyroscope is very good at finding rate of angular change, but poor at finding absolute angle. The accelerometer can determine absolute angle when the robot is stable, but is easily confused when the robot moves." I understood this to mean that "absolute angle" is the actual angle that one piece is at relative to another, not the rate at which an object is turning. For example, I thought that "absolute angle" would mean the angle of the robot heading in relation to the field.
