Hi, there are many great classical OO-design responses above.

I would use Moo (never Moose!) and Roles. (You can also apply Roles to any class or object using Role::Tiny.

Kills me but no time now to show an SSCCE for robots, but there are plenty of great examples around. I recommend SuperSearching this site for examples of Moo usage provided by tobyink (many use farm animals or humans, but I should think you can easily frobnicate that schema to your own :-) )

Hope this helps!
