Rules of the ARIAC Prize Competition 2021
The official rules for the Agile Robotics for Industrial Applications (ARIAC) 2021 have been posted at https://www.challenge.gov/challenge/ariac-2021/ .
In the meantime, here are the rules that have been used in previous years to give an idea of what they will look like.
Subject of the Competition:
In June 2017, the National Institute of Standard and Technology (NIST) put on the first Agile Robotics for Industrial Applications Competition (ARIAC). The goal of the competition was to test the agility of industrial robot systems, with the goal of enabling industrial robots on the shop floors to be more productive, more autonomous, and to require less time from shop floor workers. For the second year of the competition, we are introducing a cash prize to motivate and expand participation.
In this context, agility is defined broadly to address:
The competition Participants are required to develop a robot control system (software) to control a robot in a simulated environment. Gazebo (gazebosim.com), which is an open source robotics simulation environment, will be used as the testing platform and the Robot Operating Systems (ROS), which is an open source set of software libraries and tools, will be used to define the interfaces to the simulation system.
Software interfaces will be made publicly available that will allow the Participants to control the robot. There will be a qualifier in the April 2021 timeframe with the final competition occurring in mid-to-late-May 2021. The competition will be performed virtually in the cloud, so physical attendance is not required to compete. NIST is proposing a workshop to a major robotics conference to allow the winning Participants to present their approaches; details, when available, will be posted to the official challenge website.
Dates of the Competition:
Up to three winners will be selected. The Prize Purse for the ARIAC Prize Competition is a total of $17,500. In addition, each winner may be able to select any one representative from their team to present their results at a robotics conference in 2021 in a workshop dedicated to the ARIAC competition. NIST may be able to provide travel funds subject to availability. The number of winners will be fewer than three if there are fewer than three Participants that qualify for the competition. The Prize Purse may increase, but will not decrease. Any increases in the Prize Purse will be posted on the Event Website. NIST reserves the right to announce additional winners of non-cash prizes.
Rules for being eligible to participate in the Competition:
Participation in the ARIAC Prize Competition is open to ALL; however, not all participants are eligible to win cash prizes as explained in the next section.
Each Competition Participant (individual, team, or legal entity) is required to register on the ARIAC website. There shall be one Official Representative for each Competition Participant. The Official Representative must provide a name, username (which may serve as a team or affiliation name), email address, and affirm that he/she has read and consents to be governed by the Competition Rules. Multiple registrations per Participant are NOT allowed. At NIST's discretion, any violation of this rule will be grounds for disqualification from the Competition. Multiple individuals and/or legal entities may collaborate as a team to submit a single entry
(Participant’s code submission to a qualifier or final), in which case the designated Official Representative will be responsible for meeting all entry and evaluation requirements. Participation is subject to all U.S. federal, state and local laws and regulations. Participants must not be suspended, debarred, or otherwise excluded from doing business with the Federal Government. Individuals entering on behalf of or representing a company, institution or other legal entity are responsible for confirming that their entry does not violate any policies of that company, institution or legal entity. Any other individuals or legal entities involved with the design, production, execution, distribution or evaluation of ARIAC are not eligible to participate.
Once registered, Participants will have access to the interfaces needed to participate in the competition through the ARIAC website. NIST will create an account to allow the Participants to upload their submissions to the qualifiers. Modifications and improvements to a Participant's control system during the qualifying period are to be expected, but the Participant should have one final control system ready for the final competition.
Rules for being eligible to win a Cash Prize:
To be eligible for a cash prize:
In addition, interested Participants who do not meet the eligibility requirements to win a prize (i.e., individuals who are neither a US citizen nor a permanent resident of the United States or non-US-based entities) are encouraged to participate in the Competition. They are invited to register on the ARIAC website and download the training material. The performance obtained by these Participants will be displayed on the ARIAC website in the same manner as the performance obtained by Participants who are eligible to win cash prizes.
How to Participate in the Competition:
An interested Participant (individual, team, or legal entity) must initiate the process of participating in the Competition by registering at the ARIAC website. The party is then given access to view the documentation and download the tutorials (which provides instructions on how to run the simulations) from the ARIAC website. In the event NIST determines modifications to the documentation and tutorials are needed, all website registrants will be notified by email.
Once registered, the Participants are eligible to participate in the qualifiers. There will be two qualifiers, both occurring in the March/April 2021 timeframe (specific deadlines will be published at the official challenge website and all Participants notified by email). Participants only have to complete one of the two qualifiers to be eligible to compete in the final competition. A minimum score will be determined, based on the metrics described below, which Participants have to meet or exceed in the qualifiers to be eligible for the final competition.
During ARIAC Qualifiers/Finals, each team will submit their system so that it can be run in the automated evaluation setup. This is to ensure that teams are not using prohibited interfaces to interact with the simulation. They will have two work weeks from the date that each qualifier is released on the website (available to be downloaded) to submit their software control system that addresses the challenges in the qualifier. Registered participants will be emailed when the qualifier is released. The following files should be uploaded to an account (nfiles.nist.gov) that NIST will set up specifically for each Participant.
To allow the ARIAC Competition controllers to automatically run each team's system, teams are required to submit the following files:
The build_team_system.bash script will be run only once to setup the team's system, and the run_team_system.bash script will be run one time for each of the scenarios to be tested against.
The following terminology is frequently used in this document
ARIAC requires Participants to complete a series of tests centered in an industrial scenario that is based around order fulfillment. The robot system will work within the environment specified in the Work Environment section.
Challenges will be introduced in each scenario. Scenarios may include, but are not limited to:
The competition will consist of 15 trials: Each trial will receive a score based on completion and efficiency metrics outlined in the Scoring section.
The simulation environment is a representation of an industrial order fulfillment work cell with a robot arm, product bins, and boxes.
There are multiple product bins that may be used for order fulfillment. Products in these bins will not be replaced once used.
There is a robot arm mounted on a linear actuator. The linear actuator measures 4 m.
An automated guided vehicle (AGV) and/or drone are located at either end of the linear actuator. Orders are fulfilled at the AGV/drone. A Participant will programmatically signal the AGV/drone when the fulfilled orders are ready to be taken away. The signaled AGV/drone will depart with the shipment box.
Boxes measuring 0.5 x 0.7 m. are used for order fulfillment.
The robot arm's position is controlled through the linear actuator on which it is mounted.
The end of the arm is equipped with a vacuum gripper. The vacuum gripper is controlled in a binary manner and reports whether or not it is successfully gripping an object.
A Participant can choose which sensors to use around the environment. Each sensor has a cost that factors into the final score.
A sample of available sensors may include:
An order is an instruction containing products for the robot system to place in the box.
Each order will specify the products to be gathered.
Above the belt at a key location is a quality control sensor that detects faulty products. If faulty products are detected while Participants are filling boxes, those products should be removed from the box and replaced with another product of the same type. Faulty products are considered unwanted products: they will not count for any points when the order is fulfilled, and they will cost Participants the all-products bonus if left in the boxes (see Scoring, below).
Each trial will consist of the following steps:
The NIST Director will appoint a panel of three qualified judges. The Judges will be robot agility and/or simulation experts from inside and/or outside of NIST. The Judges will determine winners according to the Judging Criteria described herein. The Judges may not have personal or financial interests in, or be an employee, officer, director, or agent of, any entity that is a registered Participant in the Competition and may not have a familial or financial relationship with an individual who is a registered Participant. In the event of such a conflict, a Judge must recuse himself or herself and a new Judge may be appointed.
Basis on which Finalists and Winners will be selected
A portion of the scores will be automatically calculated, shared with the Participants, and publicly posted for each Trial at the conclusion of the Finals (after all Trials are run) as a combination of cost and performance metrics, described below in the Trial Score Calculation section. A Participant's final automated score is the sum of scores for each of the 15 competition Trials.
The following values are calculated for a Participant’s system setup. As Participants are to use the same system setup for all Trials, the values will remain unchanged between Trials.
The choices made by the competitors (choices of sensors) will have a specific cost associated with them. The final cost for individual sensors will be made available to the Participants at least two weeks before the Finals. For planning purposes, Participants should use:
The sum of these cost choices made by each team will be divided by a baseline cost of $10,000 and made into a cost factor for the scoring. The team costs are designated as TC, and the baseline cost is designated as BC. The cost factor, is then calculated as:
Performance metrics that cover both completion and efficiency are calculated for each Trial separately. Completion captures the quality of the orders fulfilled (that the boxes contain the correct products in the correct position/orientations); efficiency captures the responsiveness in fulfilling orders (that the orders were filled quickly).
Each trial, since it has the option to have more than one order, will have a certain set of scores for each order. Each order consists of a list of products needed and a prescribed position and orientation for each product within the box. The completion score, CS, is a combined score for each order, starting with 1 point for each product that is placed in the box. For each product that is within 3 cm of the correct position, and within 0.1 radians of the correct orientation will result in an additional point. Next, since the main focus of the competition is to have fulfilled orders, any order with all of the products in the confines of the box and in the correct position/orientation receives an additional point for each product. So, for an order s_j with i products in it would have a maximum score of:
The Efficiency of the approaches chosen by the teams are accounted for in the scoring by using the times that each team takes to complete each trial. The times are counted in seconds from the start of the trial until the first order is completed and is designated as T_01. In the trials with multiple orders, the time, T_j is counted in seconds from the time that the jth order is sent to the team. For each trial, an average of the times for each team (ATi) is compared to the individual team time to calculate the Efficiency Factor:
If a team’s system times out for a trial, the efficiency factor for the trial is set to 0 and the trial time is not used to calculate the average times for that trial.
For the multi-order trials where one of the orders is a high priority order, an additional multiplier, h, is applied with the efficiency factor to give a higher proportion of the score to that order, which is initially set to a value of 3. The final h value will be made available to the Participants at least two weeks before the finals.
Trial Score Calculation
All of the scoring factors described above are combined as shown below to calculate the score for each trial:
If there are any collisions between arms or between the robots and a moving obstacles, the score is automatically zero.
Final Score Calculation
The final overall score is the equally weighted sum of all trial scores. As mentioned in the Competition Scenarios section, trials are expected to focus on the Baseline Order Fulfillment, Dropped Part, and In-Process Order Change scenarios, among others.
Winners: The Winners of cash prizes will be determined by three Judges appointed by the NIST Director, using the Judging Criteria outlined herein.
NIST will announce the Finalists via the Event Website as well as those Finalists that have been awarded a cash award (each, an "Award"). The anticipated number and amount of the Awards that will be awarded for this Competition is set forth in these rules; however, NIST is not obligated to make all or any Awards, and reserves the right to award fewer than the anticipated number of Awards in the event an insufficient number of eligible Participants meet any one or more of the Judging Criteria for this Competition, based on NIST's sole discretion. Using the Judging Criteria described herein, three qualified Judges (appointed by the NIST Director) will determine the winners of the ARIAC Prize Competition.
The winner verification process for being eligible to receive an Award includes providing the full legal name, tax identification number or social security number, routing number and banking account to which the prize money can be deposited directly. Return of any notification as
"undeliverable" will result in disqualification. The verification form must be returned within seven (7) calendar days of receipt. After verification of eligibility, Awards will be distributed in the form of electronic funds transfer addressed to the Official Representatives specified in the winning Entries. That Official Representative will have sole responsibility for further distribution of any Award among Participants in a group Entry or within a company or institution that has submitted an Entry through that representative. The list of Entries receiving Awards for the Competition, including the names of all members of a team, will be made public according to the timeline outlined on the Event Website.
Winners are responsible for all taxes and reporting related to any Award received as part of the Competition.
All costs incurred in the preparation of Competition Entries are to be borne by Participants.
Presentation of Winning Approaches at a To Be Determined Workshop in a Robotics Conference:
Up to three Winners of the ARIAC Competition may be invited by NIST to attend a workshop dedicated to the ARIAC Competition at a future TBD robotics conference. The Winners will be required to make a 25-minute presentation on their approach in the ARIAC Competition followed by audience question and answer.
NIST may arrange and pay for the travel for one team-selected representative from each of the winning Participants to cover eligible travel costs such as airfare, conference registration fee, and lodging.
