The RANGER class is our intermediate level of competition. Aimed at middle and high schools, the robots and missions become more complex and technologically advanced. All missions are performed without looking in the pool, relying only on the sensors and cameras the team equipped their ROV with.
RANGER class is most appropriate for:
RANGER teams participate in regional events, with the top 1-2 teams (depending on the number of participating schools) advancing to the international competition.

o The Systems Integration Diagram is due at least two weeks before the regional competition. Please send all SIDs to the Underwater Robotics Shedd Regional email at firstname.lastname@example.org by April 14th, 2018. SIDs must also be submitted to the safety judges the day of the competition in order to pass safety inspection and compete. The SID must be drawn with a CAD (computer assisted drawing) program. Hand drawn figures are not permitted.
o Adult company mentors may not participate in the safety check.
o Companies should set up their marketing displays in the Northeastern Illinois University gym the morning of the competition.
o Product presentations will be given by students (location TBD).
o Adult company mentors may observe the product presentation; however, they cannot participate.
o All RANGER ROVs will be checked for size and weight limits prior to product demonstrations. Smaller and lighter ROVs will receive point bonuses. For more information see the RANGER competition manual.
o Companies shall provide a crew of at least three but no more than six people on the pool deck to operate the ROV System. Adult company mentors are not allowed on the pool deck. Communication between demo team members at the pool edge and demo team members piloting the vehicle will be limited. Only tether management issues can be discussed.
o Each company will have one or two product demonstration attempts. The number of attempts will be dependent on overall competition registration and will be announced one week before the competition when schedules are released.
o The Shedd Midwest ROV MATE Regional Competition will be offering all four Ranger Class product demonstration tasks.
o This is a new portion of the competition this year. Outreach and Inspiration efforts will be reviewed by competition coordinators and awarded 0 to 10 bonus points. For more information regarding the requirements for points, see the RANGER manual.
NOTE: By submitting any documentation, you are giving the MATE Center permission to publish these documents on its web site.
Other important notes and dates:
On competition day, RANGER companies will get one or two attempts (dependant on registration numbers) at the product demonstration. Each product demonstration time will consist of:
If you do get two attempts, the higher of the two scores will be combined with the Engineering & Communication and Safety scores to determine the total, overall score for the competition.
An event schedule will be released the week before the competition. If companies have any time constraints that they wish the Shedd to consider, please contact the Underwater Robotics program manager, Sadie Norwick at email@example.com by April 1st, 2018.
The 2018 Shedd Midwest MATE ROV Regional competition will require exclusively Anderson Powerpole connections for all classes. All provided power supplies will only accommodate Anderson Powerpole connections.
Pool: The pool has a slanted bottom. The depth for the RANGER class product demonstrations is approximately 4 meters (14 feet)
Product Demonstration Station: A table and two chairs will be provided at each product demonstration station. The standard water platform will be used for Task #2. A blank map with 0.25 meter grid lines will be available to companies at the start of the product demonstration for Task #3.
Shedd will NOT provide video monitors for RANGER class companies. Companies must provide their own video displays. See Vehicle Design & Building Specifications (3.8.2) in the RANGER competition manual for number of video displays allowed.
Diver Support: Diver support will be available during the product demonstration runs, but any diver assistance will constitute a penalty.
PFDs: Companies are not required to wear PFDs at the pool edge. Shedd will NOT have PFDs available for use.
Power: RANGER class companies will use a dedicated power supply that will provide the nominal 12 volts. Onboard electrical power or power not provided by the tether, such as battery powered devices, is NOT allowed under any circumstance. Power supply connections will be Red/Black Anderson Powerpole Connectors. Companies’ ROV system power wires MUST have proper connectors to obtain power.
Pressurized cylinders: All pressurized cylinders must be approved by the US DOT.
Shared equipment: If you are planning on sharing equipment (monitors, pressurized cylinders), please contact the Underwater Robotics program manager, Sadie Norwick at firstname.lastname@example.org by April 1st, 2018.
RANGER teams are expected to visit the safety inspection judges at the Safety Check Station during their designated time. RANGER companies should have a copy of their SID available for safety checks.
Propellers must be shrouded. ROVs that have propellers exposed will not pass the safety inspection and will not be allowed to compete. A shroud must completely encircle the propeller and extend at least 2 mm in front of and behind the propeller.
Companies that pass the safety inspection will be given a safety flag (or card). Companies must present the safety flag to the product demonstration station judge in order to compete in the pool. Companies that fail their safety inspection must address the issue and contact the safety judges to be re-inspected. Please note that only students may address the issues. Adult company mentors are NOT allowed to offer assistance.
The Shedd Midwest ROV MATE Regional will not be offering points for a job site safety analysis (JSA) or extra safety component points.
