I am studying robotics and I am focusing my attention on the sensors used on robot manipulators. I have seen that there a proprioceptive sensors, such as encoders, and exteroceptive sensors, such as range finders and sonars.
During my studies on this topics I have encoutered the concept of resolution of a sensor and I have seen in paericular that the encoder, both absolute and incremental, have a way of calculating resolution, and also exteroceptive sensors have the resolution, such as depth resolution , angular resolution and width resolution.
I am tryin to understand how everything works, but I cannot understand the concept of resolution. I have seen that the definition is :
The resolution of a sensor is the smallest change it can detect in the quantity that it is measuring. The resolution of a sensor with a digital output is usually the resolution of the digital output. The resolution is related to the precision with which the measurement is made, but they are not the same thing. A sensor's accuracy may be considerably worse than its resolution.
which I have found here.
But I don't understand this concept very well since I don't know how to apply it in the various problems and cannot idetify the concept of resolution with the various type of resolution I mentioned above.
Can somebody please help me?
