We won the Object Perception Benchmark at the ERL

.

After two nights without much sleep, we successfully finished the European Robotics League in Sankt Augustin. Special thanks go out to our coffee maker—which kept us awake—, to hamster—our honorary member—, and to the “Alumni der Computervisualistik der Universität Koblenz-Landau e.V”—which sponsored our travel.

.

With one more object recognized than our friends of team RobOTTO (Magdeburg), we won the object perception benchmark. For this task, TIAGo had to know 32 different kinds of chocolate bars and 13 small robot components. Due to some issues regarding the training of our neural network, we were only able to compete half an hour before the whole competition ended. After a mediocre first attempt, we reached 15 and 16/20 points in the second and third run respectively, and won the challenge.

.

The placing objects task also went pretty well. Though we managed to place 5/5 chocolate bars correctly into their boxes, there was a draw with the b-it-bots@Work from Sankt Augustin. In the end they won the challenge because their robot arm was much faster than ours.

Furthermore, we were the only team to make an attempt at the “serving goodies” challenge. This was a bit more difficult than similiar challenges in the past because we had to pick from a box full of chocolates and not just an object on its own. That’s probably why this attempt wasn’t very successful. However, we’re sure to be able to manage this in the near future.

ERL preparation day

.

Yesterday was the preparation day for the tournament. After a little opening ceremony, we could start testing our code. Today, the real competitions start.. So wish us luck!

.

Despite some pretty frustrating problems with the training of our neuronal network, it was a cool first day with lots of fun.

.

…and because we made so many cool pictures, the only logical consequence for us was to become instagramer. So just follow homer_unikoblenz.

ERL in Sankt Augustin

We are going to participate on the European Robotics League in Sankt Augustin (near Bonn). Our first tournament for most of the team! Tomorrow morning we have to face the probably most difficult challenge: manage to bring TIAGo from the third floor to the ground floor, WITHOUT USING THE ELEVATOR (it just broke a few days ago..).

TIAGo and our little friend - the hamster - are also very excited. :)

Storing and Disposal

The day started with a tremendous letdown of <censored>, who came a hour to late to our preparation place. This is a huge no-go in our team. But the dept was payed off in many delicious nuts and raisins. We mostly spend our first half of the day by watching the display and disposal task performance of other teams. At 2pm we started with our performance which went a bit messy because we needed to restart three times before TIAGo was able to do something meaningful. <censored> started to sweat while he was talking in front of a big crowd without having TIAGo doing something. <censored> tried his best to repair the endeffector which was not properly set by TIAGo and to fix the arena setup. Though, after the third restart, TIAGo was working as expected and worked the remaining seven minutes twice as hard to compensate for the difficult start. In the end we displayed nearly as much as hoped and demonstrated a flexible fully autonomous approach.

Here are the stocked items during a test:

Afterwards, we visited the exhibition part of the World Robot Summit and saw a whole lot of robots, including all kind of arms, a table tennis robot, a human lifelike robot and a cute Wall-e like robot. The best part was the Robot Sumo Fight Cup, in which robots had to push each other out of a designated arena area. The used robots were heavily armored and really fast. So, that was it for this day, now we are very tired and excited to go to the award ceremony tomorrow, to receive our third price for the future convenience store challenge. Finally, we can recover all the lost hours of sleep.

<censored> was trying to eat the lunch boxes during the testing session instead of supporting <censored> with testing.

In the actual test run we scored 12 points. Which is not that bad for our first try.
