ROV Water “Game #2"
Recovery
The Recovery Award is given to the team that “wins” the ROV Water Game #2 / Recovery. The team with the highest score will win the ROV Underwater “Game #2”, Recovery.
The Structure of the Recovery Game
Underwater vehicles are often used to retrieve things from the sea floor, or the floor of a harbor or port. The ability to recover objects off the sea floor depends on the vehicle’s ability to grasp or manipulate the object, and also to lift or carry it to some destination. If the object is too heavy, or it unbalances the craft, or the craft cannot get control of the object, then the vehicle cannot successfully perform its mission.
For this round, the SEAPerch ROVs must have a rod or hook of some sort fitted to their vehicle in order to retrieve rings off the bottom of the pool. The rings will have circular shape by which they can be picked up and will be of varying weight. Once picked up, the rings must be dropped into the team’s submerged collection bucket. This round will be scored based on the total mass of rings retrieved within the time limit. Considerations of buoyancy, thrust, hook placement and attachment, and ballasting in your ROV design become very important in this round. The rings are color-coded based on their weights. The heavier objects are worth more points since the team will be required to do more extensive engineering calculations to retrieve the heavier weights.
The scoring will be as follows:
Ring Color |

This Underwater ROV game will be scored based on which teams can successfully recover rings from the bottom of the pool in a configuration that scores the highest points.
- Each team will compete in the Recovery Game one time.
- The course will consist of a collection bucket and a collection of objects to recover.
- The Recovery Game will be scored by adding the total points for all objects collected added together. The team with the highest score will win the Recovery Game.
- The Recovery Game will last for 5 minutes. A stop signal will sound at 5 minutes; at this time, all operators must place the ROV objects they are holding on the ground.
- The objects to recover will be circular in shape with an approximate 6inch diameter.
- In the event of a tie for first or second place, a final ‘round’ will be played.
Game Rules:
- The ROV MUST touch the wall at the start of the game, an operator should hold the ROV in place until the start signal is sound.
- The ROV Controller must be on the ground at the start of the game; when the start signal is sound, an operator may pick up the controls.
- The ROV Controller must be placed on the ground when the end of game; signal is sound. The ROV Controllers can be picked up when the Head Referee gives permission.
Provision for False Start:
- If a team has a “false start” defined as (a) the ROV has left the wall before the start signal OR (b) an operator has the controller in possession prior to the start signal; 5 points will be subtracted from that team’s score.
Provision for Possession of ROV Controller after End of Game Signal:
- If a team has possession of ROV Controller after end of game signal: 5 points will be subtracted from that team’s score.
