Apple Picking: Less Humans More Robots

Homework for this week: Design an apple picking machine. Anything goes, it just has to pick apples from a tree and bring them down.

Additional possible constraints can include:
- pick only ripe or semi-ripe apples
- don't damage apples and trees
- transport apples to a storage area
- can operate 24HR7
- safe for workers
- green for environment
- sustainable
- easy to maintain
- usable in many types of orchards

Ok, with that in mind, I shall ignore all the additional possible constraints and just brainstorm all possibilities. :) Nutty... nutty... :P
