On Competition Day there will be three competition events: two Pool Events and one Poster Presentation. All events will comprise three classes: Middle School, High School, and Open class, with each class competing in two in-water events and the Poster Presentation.
For each of the classes, trophies will be awarded for the first three finishers in each pool event. Also, trophies will be awarded for the top three finishers in the poster presentation competition in each of the three classes.
Only two team members are allowed on the pool deck during a competition.
All team members must wear shoes with rubber soles on the pool deck.
Each SeaPerch ROV must be presented for a compliance check during check-in on Friday night, or on Saturday morning and approved by a judge prior the team competing in the pool events.
In the event that a vehicle is inadvertently interfered with during a competition, or a malfunction of a vehicle's parts (i.e., the motor) occurs that is beyond the design and construction, the lead pool judge will have the sole authority to provide the team time to fix their vehicle and to allow them to compete later in the round. Malfunctions will be evaluated on a case-by-case basis. The 12V power system will be available for all that wish to use it. It is designed to work with the alligator clips in the SeaPerch kit. Each lane will have its own power connection.
Teams are encouraged to think outside the box and change the shape and configuration of the SeaPerch ROV.
Vehicles shall consist of the parts and components contained within the equivalent of one SeaPerch kit, with the following exceptions:
Vehicles should consist of the parts and components utilized within the SeaPerch kit to the maximum extent possible and shall be subject to the following:
Teams have no budget limit. (Budgets should be tracked for presentation to Judges during poster presentation)
Hooks and attachments MAY NOT added/removed depending on the competition round.
Teams may only utilize stock SeaPerch motors in thrusters (Jameco P/N 232022).
Teams will design for and utilize a 12-volt power source. A 10-Amp Max fuse shall be used for safety.
The vehicle may be reset by the teams during the competition
The vehicle cannot be dragged via the tether.
Sportsmanship is expected at all times. Should a protest or dispute occur during the competition it is the intent to resolve the grievance at the time it occurs, and the ruling by the Head Judge shall be final.
A team that wishes to have an issue considered shall send the student team captain and one additional student member (2) to the lead judge with the inquiry or question. The lead judge will make the decision on the issue, and this decision is final. The same issue may not be brought to the judge a second time by any member of the team. Adults may not approach the lead judge on the pool deck regarding any perceived issues.
Teams may not question the legality of other competing vehicles; it is the Head Judge's role to determine if vehicles meet the entry and compliance requirements.
Unsportsmanlike conduct is grounds for the disqualification of a team. Team members and advisors are responsible for the conduct of all members and adults accompanying the team.
Each event will be scored in accordance with its published Rubric. Scores for each event will then be ranked from 1st-?? for both their class and overall stock.
Each teams rank in the individual Events will be added together and then ranked in order to determine overall Class Winner and overall Stock Winner
Here is the simplified scoring sheet used at nationals:
Scoring ties will only be broken where trophy places require. (i.e. ties will not be boken when ties do not effect top 3 results in any event or class overall)
Obstacle Course ties to the 100th of a second will be broken by the faster time in the secondary run.
Challenge ties to the 100th of a second to the same point total will be broken by rerunning a portion of the course. The winner will have 1/100th of a second removed from their time, breaking the tie.
Class Ties will be broken based upon the best performance in the following priority:
Any other ties not covered by this will be broken by a team of well trained monkies with darts.
An underwater remotely operated vehicle (ROV) must be able to maneuver successfully under its own power. If a vehicle cannot maneuver to the appropriate location to perform its task, the vehicle is of no use.
The submerged obstacle course involves large rings (18" minimum diameter), oriented in any direction, through which the vehicles must travel. Teams must navigate through the obstacle course, surface, then re-submerge and return through the course to the end. Consideration of optimal maneuverability, control and speed should be given when constructing your SeaPerch (thruster placement and orientation, tether attachment, buoyancy and ballast, etc) and control box. Scores for this round will be based on the fastest time for successfully navigating the obstacle course.
NOTE: RING SIZE HAS CHANGED!
While many roles for ROVs require power, most require the ability to Collect and control samples and items in the water.
This 2015 National Challenge task will require students to release objects and transport them in a controled manner.
The course consists of three stations in which the vehicles will have to maneuver and actuate equipment in the pool. The max pool depth for this event is 7'
Scoring: Max points in the shortest amount of time. The clock stops when the team identifies they are done, surfaces and touches the wall with the vehicle. Teams may stop the clock at any time, but it will not be restarted. Teams must inform the judges at the time if they wish to stop the clock and lock in their scoring.
Who dosn't love gumballs? Well we do! So do SeaPerches.
There will be 4 dispensers with different sized balls in each. The balls in three dispensers are Wiffle balls of various sizes float and are released up to the surface. The fourth dispenser will house real golfballs and they sink.
There will be three different sized Wiffle balls to be released, golf ball (1.68"), baseball (2.86"), and softball (3.82") The ones used for nationals can be found here: The Connecticut Store
The golf balls (1.68") used for nationals can be found here: GolfBall King
Each released wiffle ball can then be brought to either a pen on the surface or to a submerged container. More points will be given to placing the balls into the submerged container.
The golfballs will have to be herded into a scoring area on the floor of the pool. (more details to follow)
The "floating pen" will be a floating line on the surface of the pool 1 foot from thr wall. all balles will have to be within this area to be scored.
**The submerged container is still being reaserched, but will be no larger than a milkcrate. Depth of the container is also being determined.
**Golf ball scoring areas are also under development.
****Solidworks Files will be available soon.
Plans and assembly drawings for the challenge
REMEMBER: While the details of the Nationals course are provided, a "true to plan" device is not needed to gain proficiency. Determine what actions and skills will be needed this year and make practice devices to hone theese skills.
The 2015 National SeaPerch Challenge again brings the opportunity for SeaPerch competitors to share their learning, building, and science understanding through poster displays and presentations. This year, all teams will compete in Poster Display judging. The top teams in the poster display portion will be offered the opportunity to present in-person to a panel of judges. Scores for the poster displays and for the presentations will be added to each team’s total points.
Please read the following carefully as your team plans for the National SeaPerch Challenge.
