Virtually visit us at CV-Tag 2020!

With this year’s robotic competitions all postponed due to COVID-19, our team’s non-robot members had to put health first in the last few months, keeping distance to each other and our labs. Despite restricted physical access to our robots, everyone worked from home to improve their RoboCup game implementations. Using prerecorded sensory data, we have been able to simulate scenarios in which Lisa and TIAGo normally have to solve tasks on their own. In the past few weeks, our laboratories could slowly be reopened, paying careful attention to a maximum number of people on site and general hygiene measures.

For now, we invite you to “come” see us at CV-Tag 2020 (“day of computational visualistics 2020”), an annual event at Campus Koblenz of University of Koblenz-Landau where students present their projects and thesis results. This year, the event will completely take place online. So you will be able to examine various fascinating results from whereever you currently are! The projects will be shown in a live stream, including our final presentation of this year’s student team. Due to the circumstances, we have to be economic about the time spent at the university and the number of people involved in filming videos, but we are doing our best to compile an interesting roundup of our results anyway! :)

Other highlights of the event include presentations by companies, interviews and a big raffle at the end. If you’re interested in the CV-Tag event, have a look at pictures from last year and add the Facebook event to your agenda.

See you there!

RoboCup German Open 2020 cancelled

Sadly, the RoboCup Major competitions of the RoboCup German Open in April have been cancelled due to the corona virus pandemic. The University of Koblenz-Landau has also cancelled all on-campus courses for the time being, so we will have to stop cuddling up in our small lab. Even so, we are optimistic that the RoboCup world cup in June will take place (Fingers crossed!). We will do our best to prepare for it from home and by taking extra safety measures when testing with the robots in the lab.

Lisa visits RobertaLab

Last Friday, Lisa took part in the season closing event of RobertaLab. RobertaLab offers robotics and programming workshops for girls. You can find out more on their website: RobertaLab Koblenz

Since RobertaLab also takes place at the University of Koblenz, this was just a short walk to another building for Lisa (it was slightly longer for the human companions who had to make the trip multiple times because of forgotten power wires and keyboards). Lisa served as a greeter at the beginning of the event and later supported the certificate awarding ceremony with complementary praises, all with her unique German accent.

Afterwards, the RobertaLab participants showcased their Lego Mindstorms projects. Maybe some of them will join team homer for the RoboCup 2030? We hope that Lisa will get a new paint job by then.

New year, new labels

Here at team homer we start the new year by spending hours labelling cups, cutlery and long-expired food items in pictures. Because we know how to have fun.

For those who aren’t familiar, labelling simply means to mark the region in an image where a specific object is. We do this for many pictures and then feed the labelled images into a neural network. This way, the network learns how to recognize the trained objects in new pictures even with perspectives not seen before.

We labelled more than 300 pictures of our many test objects, so Lisa and TIAGo should now be better equipped for recognizing and grabbing the right objects in the coming tests.

The whole group procrastin... concentrating on creating the perfect labelling set design.

Dear diary, it's day 23 of labelling. I'm beginning to develop violent fantasies about smashing this hard-to-label translucent cup.

As service robots, Lisa and TIAGo can recognize all your cutlery (as long as your household only uses childproof plastic cutlery from a certain Swedish furniture concern).
