Step 1: Identify the Problem

Your challenge, should you choose to accept it, is to design and build an underwater Remotely Operated Vehicle (ROV) that follows basic engineering and science concepts with a marine theme. Your ROV must successfully be able to dive under water and maneuver a designed obstacle course in the shortest amount of time possible.

Criteria:

• ROV must be waterproof.
• ROV must be able to hook/grab and maneuver rope rings that are made of 18" of rope.
• ROV must be able to hook/grab and maneuver PVC cube.
• ROV must be able to maneuver under its own power.
• Teams may utilize materials (quantity and components) equivalent to one SeaPerch kit.

Constraints:

• ROV must not exceed 18" in height or width in order to fit through the 18" diameter hoop obstacle course.
• $20 budget for supplemental materials.
  • 3D printed parts will be costed out at $0.05 per gram
• Hooks and attachments MAY NOT be added/removed between competition rounds.
• Additional NON-stock motors may be utilized for actuation or other non-propulsion uses.
• Only allowed to use stock SeaPerch motors for propulsion.
• Teams may only utilize three (3) thrusters.
  • A thruster is defined as a means of propulsion for the SeaPerch, normally but not limited to a motor and propeller assembly.
• Teams will design for and utilize a 12-volt power source.
  • Power source other than the included kit battery or venue supplied power is not permitted.

Step 2: Gather Information (Research)

• Define buoyancy and what it has to do with building your ROV.
• Define displacement and why it's a factor in the design/build of your ROV.
• What is propulsion and describe its use with your ROV. In other words, what purpose does it serve on your ROV?
• What is soldering and how will this process be used during the construction of your ROV?
• Provide at least 3 examples of real-world applications or uses of underwater ROVs.
• Why does motor placement/configuration matter to the efficient operation of your ROV?
• How do you determine an adequate balance between speed and accuracy? Is one more important than the other?
• What other skills and knowledge will prove useful for the completion of this challenge?
