The Qualification Guide has also been updated for Cave Circuit, and the Cave Circuit qualification world is now available for the Virtual Competition. Details regarding qualification:

2. The scoring threshold for successful Virtual qualification has been updated for the Cave Circuit.
3. Eligible Systems teams will receive qualification waivers for the Cave Circuit via email.

As a reminder, new teams that are interested in participating in the SubT Challenge must first complete Team Registration before submitting qualification materials.
Getting Started with *Hello (Subterranean) World*
The first of many Hello (Subterranean) World posts has also been released to introduce new competitors to the SubT Virtual Testbed.
We look forward to seeing your technology developments for Cave Circuit and, above all, hope your teams stay safe and well.

23rd April 2020 — Systems Competition Cave Circuit Waiver

Urban Circuit Systems Teams,
We hope you are staying safe. This is a notice that your team has received a Team Qualification waiver for the Cave Circuit of the Systems Competition based on your successful participation at the Urban Circuit event.
Please note that you are still required to submit a letter of intent (LOI) to participate by the Team Qualification deadline. You are also still required to qualify any new platforms by the Platform Qualification deadline. Specific dates for deadlines will be released upon being finalized.
New for the Cave Circuit is the Team Portal which is a centralized way to capture and maintain all team data such as contact information, team roster updates, systems enrollment, and Qualification/Letter of Intent (LOI) information, throughout the remainder of the SubT Challenge.
Please reference the latest version of the SubT Challenge Qualification Guide for details related to the LOI and Platform Qualification requirements.
Good luck! The SubT Challenge Team

25th June 2020 — Robotika Cave STIX01

On Saturday June 20th was our first STIX (System Integration Excercise) in caves. Thanks to starting cooperation with Speleology Group Tetín we could participate in the climbing day in Chlum near Srbsko.

The weather was horrible — it was raining already several days, and as I learned in Chlum weather does matter even in the cave! That was lesson number one, that caves are always wet (at least here in Bohemia) and the rain water has to go somewhere. So it is dropping from the ceiling, creating muddy and slippery surface.
We had very nice shelter — see the pictures from Martin Majer:
It was relatively dry there (when compared to the outside) and we could exercise basic motion with stones, water, darkness …
The second chapter was excursion into the cave …
Now should come the „lessons learned” and what we will do about it, but it is late and let's start this blog now and continue later …
p.s. it turned out that in this part of Czech Republic there are plenty of natural caves, see the list on http://1-02.speleo.cz/wp/soupis-jeskyni-v-okoli-tetin/
