22nd April 2020 — DARPA SubT Challenge Cave Circuit Announcements
We have a few big announcements that were posted to the Community Forum today regarding Cave Circuit which pertain to both Systems and Virtual Competitions, outlined here briefly.
As noted below, we are transitioning qualification materials to a Team Portal. Your Team identifier for your Systems Profile is XXXXX. Your Team identified for your Virtual Profile is XXXXX.
Schedule Shift of the Cave Circuit
First, due to the circumstances and restrictions surrounding COVID-19, Cave Circuit will be no earlier than October 2020. We welcome updates on the schedule shift’s implications for your team, which can be sent to XXXXX.
Cave Circuit Artifacts Announced
The two event-specific artifacts for Cave Circuit have been announced in the updated Artifact Specification Guide. Virtual models of both artifacts are available on the SubT Tech Repo.
Qualifications for Cave Circuit
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:
1. All qualification materials will now be submitted via the SubT Challenge Team Portal. Previously submitted team data will pre-populate if the profile is created with your one-time-use Team Identifier(s).
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.
4. All Virtual teams will need to qualify using the Cave Circuit qualification scenario, i.e., no qualification waivers will be issued for Cave Circuit.
5. Qualification deadlines will be announced at a later date for both Systems and Virtual Competitions.
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.
Sincerely, The SubT Challenge Team
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/
23rd July 2020 — System Cave Circuit was CANCELED!
Bad news. Today I received e-mail from Tim with subject: SubT Challenge Updates (2020-07-21).
Given current COVID-19 considerations and in the interest of prioritizing everyone's safety, we have made the difficult decision to forego the Systems Competition for Cave Circuit.
We recognize and share your team's passion and desire to showcase and compete all of your hard work since Urban Circuit, and we're eager to continue creating compelling -- but above all, safe -- environments and experiences to highlight your innovative technologies. As we set out to challenge your team to "learn lots, have fun, and be safe," as program manager, I am committed to your health and well-being as well as that of our global community, and to being as inclusive and supportive as possible for the entire extended SubT Challenge family.
We will still host the Cave Circuit for the Virtual Competition, offering opportunities to accelerate SubT technologies and carrying the energy and enthusiasm of the Circuits ahead of the Finals Stage of the SubT Challenge. Thank you for your continued efforts in the Virtual Competition, and congrats on your three points on the Cave Qualification world. For your awareness, we’ll soon officially be announcing the full Cave Circuit schedule and details in the near future.
… so this is it. The next stop is the finals in August 2021, if the world recovers. Sad, but taking into account the current circumstances, it is unfortunately not surprise. We will see if Robotika team can be enough self-motivated to move on in cave environments. The focus will now shift to Virtual Cave Circuit. The official DARPA announcements are typically on Friday, i.e. tomorrow. My guess is that Virtual will be held on October 2020 … but that will continue in different blog …
p.s. yes, there are several new drones developed for System Cave Circuit, but hopefully we will see them in action on Robotour 2020.
9th December 2020 — Cave Environment Preview
DARPA presented yesterday original cave preview, as it was planned for the last summer, but had to be canceled due to COVID-19 situation. It was part of SubT Challenge Competitors Summit - Technical Workshop & Entrepreneurs Day - December 8-9, 2020. Enjoy!
