COMPETITION DETAILS AND SCHEDULE OF EVENTS

SOFTWARE CHALLENGE WINNER


2021 Software Challenge Winner Announced

The Software Competition has now ended.

Congratulations to the University of Illinois at Urbana-Champaign's “Illini Leapfrog” Team for winning the ARTEMIS LEAPFROG Software Challenge. Out of the seven total teams that took part, Illini successfully showed guidance and navigation functions operating the LEAPFROG vehicle over a simulated Lunar landscape. As the winning entrant, the Illini team will receive a LEAPFROG vehicle flight kit for their own build and development in Fall 2021.

This simulation video shows the University of Illinois teams control of the LEAPFROG vehicle while flying in the sample world provided to the teams for coding and testing their systems.

This simulation video shows the University of Illinois software competition team's code flying the LEAPFROG vehicle in the Competition world. Each teams code was run 5 times from different starting locations in the world, to test their robustness and resilience. Even with a harder landing, their vehicle was able to correct attitude and land successfully within the craters. Congratulations to the Illini Team!

When asked to comment on the conclusion of this year's LEAPFROG challenges, Prof Dave Barnhart, the lead faculty mentor for the student LEAPFROG TEAM, says: “this is a wonderful achievement and I am very proud of this team. I am very proud that an all student team from Southern CA could assemble and create a working simulation environment in such a short time and enable other students around the country to learn, develop and participate in a challenge that was originally not planned. This is a testament to the student resilience and capabilities around the country today!"

From the LEAPFROG team to all competitors and spectators: thank you for participating!

The 2021 Lunar Entry and Approach Platform for Research on Ground (LEAPFROG) challenge is a multi-stage student competition funded by NASA’s Artemis Student Challenges Program. It consists of a software challenge through a simulation followed by a vehicle-building for the top teams across the country. The competition will be held starting May 2021.

SOFTWARE CHALLENGE

Crater Landing OV1

Virtual Simulation Challenge (COMPLETED FOR 2021)

The software challenge has run and a winner was selected, congratulations!

The following documents and links show the webinar recordings that described the challenge and how to execute, and the documents are archived for those wishing to review and/or create their own in the future.

Webinar 1 (April 7th at 1 pm PST): Overview
Recording
This webinar introduced an overview of the LEAPFROG Competition as a whole, and the software required to setup your simulation environment. This included the basics of PX4, ROS, Gazebo, and MavRos.

Webinar 2 (April 30th at 1 pm PST): Simulation Setup
Recording
In this webinar, you and your team will learn how to add new plugins to the PX4 Software specific for the LEAPFROG vehicle and simulation, and how to link the various software elements together. The software team will provide more detailed instructions on setting up the simulation environment, and how it operates.

Webinar 3 (May 12th at 1 pm PST): Simulation Modifications
Recording
In this webinar we will introduce you in how to modify the behavior of the LEAPFROG vehicle within the simulation, and you will also be learning about our competition scoring rubric.

Webinar 4 (May 21st at 1 pm PST): Scoring Criteria and Challenge Goals
Recording
In this last webinar we will go through the scoring criteria, show an initial “lunar world” with craters for your use, and describe how you upload your code/algorithms to the Software Challenge Github when you have completed your challenge results. We also will describe how winners/participants will get kits upon the final scoring and notification!

Following the software challenge’s conclusion, the top-ranking teams around the nation will receive full lander kits (without the jet engine) which includes all parts needed to construct a full Artemis LEAPFROG prototype vehicle. Subsequently, a summer “boot camp” will walk teams through the construction of their vehicles. The boot camps will also provide information and ideas on how each team can develop infrastructure to conduct attitude control testing to validate their control algorithms developed in the software challenge on their own “air bearing” fixtures.

Boot Camp and Exhibition Details

Summer 2021

For more information see Registration.
During Summer 2021, the winners/competitors in the software challenge will each receive a complete LEAPFROG lunar lander kit (except for the jet engine)! The LEAPFROG team will hold a series of building boot camps that will guide each of the teams through the assembly, construction, and integration of their vehicle. The LEAPFROG team will provide input on how to develop a simple lab-based “air bearing” test stand to actually test the vehicle and showcase each team's ACS code! In parallel, the LEAPFROG team will run actual exhibition flights that will be live-streamed to all teams to give them direct understanding of how the vehicle flies and operates using the code and software they developed.
Vehicle Build and Test Updates
The first static hold down test of the vehicle avionics, structure and jet engine was run in late April! The engine fired up completely autonomously through onboard avionics and ground commands, and verification of basic control and data transmission to the ground station worked correctly. The team also verified ACS commands to the valves worked and calibrate pressure drop at the valves and power draw on the vehicles batteries.
Watch them here! (Turn up the volume on the video, it’s a real jet engine!)

Public Release

LEAPFROG’s first official public release

From the NASA press release: “[The University of California, San Diego] will develop a Lunar/Martian Lander skills competition, using existing technology to execute the competition in Earth’s gravity and atmosphere. The competition requires competitors to develop and demonstrate Artemis-relevant systems engineering skills by building a lander free flier and navigating it through a 3D obstacle course. This team includes a co-investigator from the University of Southern California in Los Angeles, working in partnership with the Space Science Laboratory at the University of California, Berkeley.”

Artemis Student Challenges

LEAPFROG’s parent program

Artemis Student Challenges are a new set of coms and initiatives funded by NASA to engage and inspire college students, as well as younger students for a few select challenges. These challenges aim to solve various problems faced by space explorers (both the human and robot variety) through teamwork and creativity.

Artemis Program

NASA’s mission to return to the moon

From the NASA press release: “[The University of California, San Diego] will develop a Lunar/Martian Lander skills competition, using existing technology to execute the competition in Earth’s gravity and atmosphere.
