DESCRIPTION

For several years the Tech United team from the University of Eindhoven has been one of the most dominating teams in the Robocup Middle Size League (MSL). In 2012 they became world champion. In 2013 they were very close but lost in the extra time of the finals. Every year you can see the same teams fighting for the title, even though the software and drawings are made open source after every tournament the less developed teams cannot keep up with the top teams. There are several reasons why they cannot keep up. Some teams simply do not have enough budget, others do not have the knowledge or capacity to build a robust robot or they have mostly software engineers and no mechanical or electrical engineers. This is where the Turtle-5K project kicks in, an affordable MSL robot redesigned by ACE (hardware), VEDS (electronics), Frencken (production/assembly) and the TUE (software) for these specific teams. The goal of the project is to build a robot that has the same specifications as the 2012 world champion of Tech United (called Turtle) but for 20 percent of the cost price. This meant a cost price reduction from 25 thousand to 5 thousand euro, hence the name Turtle-5K. During the presentation Niels Koenraad will show how he and his team achieved this goal and will go into more technical detail of the robot. This includes the open source software they used and developed for this robot.
