At the moment I am mentoring a high school robotics building team and I came across a problem that I need a little help with. For a potential sensor we are considering using a digital semicircular sensor capable of measuring angular position.
The sensor must have be able to measure the angular position to a precision of 0.3 degrees.
My questions are:
What is the number of concentric rings and on-off sensors are needed to achieve this precision?
Is their a simple formula that I'm missing here, it appears like this could be easily solved with some knowledge of this type of sensor.
I apologize that I cannot give too much detail on the subject, It just so happens that I am actually a chemistry teacher and don't have much experience behind the formulas that govern digital rotation sensors.
Regards,
Mr. Evans
