PRE2015 4 Groep2

(Wiki markup cheatsheet)

We are developing an autonomous harvesting robot. The robot will be initially developed for harvesting strawberries. As creating a complete prototype is not feasible to do in nine weeks, we focus on the sensing part. For that we will develop a system which scans fruits and determines their ripeness. It can also consider other factors like for example if the fruit looks appealing.

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.
