Team Statement and Documentation

Metrics: Measurement of Capabilities – Whole System (also used for Optional Mid-Stage Progress Review)

 

Contestants will be evaluated on the basis of the following metrics. Competition organizers will provide additional resources on Open Test Lane and Test Methods at the outset of the stage.

Measurement Description Metric to Maximize
1 Inspect and Download Data

Perform the 10 minute Inspect Payload test of the Open Test Lane (PAY) while downloading data from the Target Objects of Interest. Transmit collected imagery and data to the Command Server.

The Open Test Lane will be set up as follows:

  • At the scale of S = 6 m (20 ft).
  • Implemented using 10 cm (4 in) buckets.
  • Taking no more than 10 minutes.
  • Inspect the Landolt-C target in each bucket to the second ring, representing a level of acuity of 3.5 mm (0.138 in).

Maximize the amount of unique data downloaded from the Target Objects of Interest and transferred to the Command Server.

There is no advantage to achieving a level of acuity beyond that specified.

For every minute (rounded up) that human intervention is required, 10% will be deducted from the test score, up to a maximum of 50%.

2 Survey Acuity

Perform the 10 minute Embedded Survey Acuity Test while downloading data from the Target Objects of Interest. Transmit collected imagery and data to the Command Server.

All Target Objects of Interest must be inspected to a level of detail that will be specified in the procedure, approximately equivalent to the ability to resolve 3.5 mm (0.138 in) features.

Maximize the amount of data downloaded from the Target Objects of Interest and transferred to the Command Server.

There is no advantage to achieving a level of acuity beyond that specified.

For every minute (rounded up) that human intervention is required, 10% will be deducted from the test score, up to a maximum of 50%.

3 Autonomous Obstacle Avoidance Autonomously fly between two points, avoiding an obstacle in between them. Maximize the number of iterations in 10 minutes without hitting the obstacle.
4 Endurance (time) Perform the Test Method for Endurance, aiming to fly for as long a duration as possible while completing at least one iteration.

Maximize flight time on one battery charge.

There is no advantage to completing more than one iteration.

5 Endurance (distance) Perform the Test Method for Endurance, aiming to fly for as many iterations as possible.

Maximize the number of iterations of the test on one battery charge.

The flight time is ignored.

Metrics: Best-in-Class

 

The best performing contestant in each of the following subsets of the Main Contest tests (some maximized with respect to different metrics) will receive respective Best-in-Class awards. They will also receive an invitation to demonstrate their capabilities in Stage 3 if they are not otherwise selected on the basis of the leaderboard ranking.

The purpose of the Best-in-Class awards is to encourage the participation of contestants who may have a specialization that meets a specific need, even if they do not have the resources to field a system that can compete in all the competition tests. Therefore, NIST PSCR encourages contestants who are only focused on one of the following subsets of tests (in addition to the Required Specifications) to participate. 

Capability

Description

1

Best-in-Class Endurance

Achieve the most iterations in the Endurance (Distance) test over one battery charge. 

2

Best-in-Class Inspection and Survey Acuity

Inspect, to the highest level of detail, the largest number of targets across all Target Objects of Interest, across the Inspect and Download Data, and the Survey Acuity tests. 

Amount of data downloaded and human intervention penalties are ignored.  

3

Best-in-Class Radio

Download the most amount of data across all Target Objects of Interest across the Inspect and Download Data, and the Survey Acuity tests. 

Inspections and human intervention penalties are ignored. 

Capability 1 of the Best-in-Class Contest is identical to Measurement 2 of the Main Contest. Each team’s latest result for Measurement 2 of the Main Contest is therefore automatically considered for Best-in-Class Capability 1. 

 

While Best-in-Class Capabilities 2 and 3 make use of some of the same Measurements as the Main Contest, contestants may score better by flying in a different manner to the way that they did in the Main Contest. For example, a team may maximize their Best-in-Class Capability 2 score by spending equal time inspecting each Target Object of Interest to their best level of acuity. In contrast, in the Main Contest they might aim to only achieve the required level of acuity and instead focus their time on downloading from Target Objects of Interest that have radio transmitters. Therefore, contestants who wish to be considered for Best-in-Class Capabilities 2 and 3 shall submit separate results and accompanying videos for each of the two Best-in-Class capabilities’ tests in each of Best-in-Class contests 2 and 3. These may also be resubmitted as many times as contestants wish, with the latest results being considered. 

 

Note that contestants must use the same UAV, in the same configuration, for their Main Contest and Best-in-Class Contest entries. A team who updates their UAV to a new configuration for one contest must re-submit new measurements. 

Stage 3

This section lists the various specifications for Stage 3. See the Glossary for specific definitions of terms used. Competition organizers will also provide additional resources at the outset of the stage to assist in the interpretation of these specifications.

 

Contestants must comply with the same Required Specifications as listed in Stage 2 with the following adjustments.

 

Positive Aircraft Control using the Supervisory Controller

Contestants will be expected to demonstrate this requirement in person at the Stage 3 event before being permitted to fly the Stage 3 scenarios.

Low Battery Behavior

Contestants will be expected to demonstrate this requirement in person at the Stage 3 event before being permitted to fly the Stage 3 scenarios. This may be demonstrated as part of the Endurance test.

Safety Plan

Contestants invited to participate in Stage 3 may be provided with feedback on their safety plan at Stage 2 on aspects that they must address prior to satisfying the requirements for Stage 3.

Measured Specifications and Capabilities

The Stage 3 Contest will see contestants rotate through a test method station and one or more scenario stations. Each station results in a team score, which is normalized to the highest score at that station. The leaderboard is based on the sum of each team’s normalized scores across the stations.

 

At the test method station, contestants will perform, live, the tests they performed for the Stage 2 Metrics for Main Contest, and their score will be computed accordingly. They may perform as many of the tests, as many times as they wish, within the allotted time. The best measurement for each test will count.

 

At each scenario station, contestants will fly a mission in a scenario that resembles a public safety use case, relevant to the challenge application. For example, the scenario might be a simulated mass casualty event in an urban area, with simulated victims (mannequins) in and among a collapsed structure, cars, and so-on. There will be a number of Target Objects of Interest in the environment, in locations that are operationally relevant, such as next to the simulated victims. Some may be out in the open, some may be in obstructed or confined areas. The radio transmitters at the Target Objects of Interest will include similar capabilities to the ones contestants build for their own testing in Stage 2. They may have additional capabilities for measuring connection quality. Details and sample code for contestants to perform their own testing will be made available prior to the launch of Stage 3.

 

The scenario may require the UAV to fly beyond line-of-sight and/or radio communications of the Base Station. (The Remote Pilot in Command, with the Supervisory Controller, will be in a separate location where they can maintain communication and visual line-of-sight to the UAV.) Over the course of the allotted time, the team shall maximize the number of target items read/identified, and maximize the amount of data gathered from the Target Objects of Interest and transferred to the Command Server. The scoring formula will incentivize the collection of data from multiple Target Objects of Interest, rather than just focusing on collecting data from one.

 

Contestants will be allowed five minutes of hands-on time at the start of the mission to set up and launch their system from a stowed state. For every additional minute (rounded up) that human intervention is required during the rest of the mission (meaning any input from any human to the system, via any modality), 10% will be deducted from the measurement for that test before computation of the normalized score, up to a maximum of 50%. Administrative intervention, such as addressing another aircraft that has unexpectedly appeared in the airspace, is exempt from this penalty.

 

Contestants may visit stations more than once as scheduling permits. Only their highest score in each station is counted. Each run of a given test station  be as if it was approached anew, contestants shall not use information gathered prior to the current mission (e.g. during practice, or a previous mission in the same station), such as maps and waypoints. Competition organizers may take measures, such as adjusting the station periodically while keeping the difficulty level the same, to prevent and detect re-use of previous information.

Team NavigateIO is the Stage 2 midstage winner!
