Group One
The Wave-Powered Autonomous Surface Vehicle
Energy storage limits the autonomy of Autonomous Surface Vessels (ASV). Aside from wind and solar energy, surface waves can provide enough energy to store (e.g. by replenishing batteries or a compressed air tank; there is no constraint on the type of energy storage, so long as it can be recharged using wave energy) and actuate the propulsion system of the ASV.
The group shall design and implement a Wave-Powered ASV capable of traveling between two waypoints parallel to the shore and no less than 200 [m] apart in 600 [s] or less, in 0.3-1 [m] waves. Operation shall take place away from the surf zone.
System Level of Requirements:
Develop a Wave-Powered ASV that can
- With the energy storage at full capacity, travel between two waypoints parallel to the shore and no less than 200 [m] apart in 600 [s] or less, in 0.3-1 [m] waves. During the mission, the amount of energy used to move the ASV and the amount of wave energy stored by the vehicle shall be measured. The ASV shall reach each waypoint to within a 5 [m] accuracy. There is no constraint on the type of energy storage, so long as it can be recharged using wave energy. The design shall handle current coming from any direction. The current speed shall not exceed 0.5 [m/s] in any direction.
- Requirement 1 + complete the mission starting with no energy stored to begin with. The ASV shall first store the wave energy for the period of time necessary to complete requirement 1 (it can be attached to a Research Vessel located near the first waypoint and released when ready).
- Requirement 2 + complete a round trip between the two waypoints.
Operating Requirements:
- Two-person deployable/recoverable from the R/V McAllister
- Diver-less operations.
