Explicit units for measurements and calculations

[jpas]

It would be useful to have type checking for all our units that we use, in the GPSDriveProcess alone I have needed to use:

• radians
• degrees
• metres
• rpm (for wheels)

Right, at the very least these should be documented better. I'll go through the code base this evening to update more of the documentation, there are other things that need updating as well.
Do you know of a good way to associate units with values in python? I'd rather not have to use a third party library just for that.

You could create a class that contains two instance variables: one for the numerical value, and one for the unit of measurement. Then you can use this class to compare units. Is this what you have in mind Jarrod?

That is part of what I had in mind, we could also implement the standard mathematical operations for these unit classes.
