==Notes==
==Notes meeting 1==
Moved to [[Talk:PRE2015_4_Groep2]].
Goal: Create a demo in which a robotic system is able to detect ripe strawberries and harvest them effectively.  
 
Subsystems:
Robotic arm
Machine Vision/Learning
 
Requirements for presentation:
-USE needs (Yannick + Raomi Team Awesome)

Amigo sandwich baker

Make Amigo able to make sandwiches.

Standalone sandwich baker

Create a new device that is meant purely for creating sandwiches in Subway style (i.e. with ingredient picker).

State of the art

A small number of tests have been done with machines for harvesting strawberries. These are large, bulky and expensive machines like Agrobot. Cost prices are in the order of 50,000 dollar. Todo: add citations.

A lot of research is done towards inspection by means of machine vision. Todo: add citations and continue.
