Note: Additional WiFi protocol information will be included in the competition manual.
· Install the base on the bottom
· Install the turbine onto the base
· Latch the turbine in place
· Transport the I-AMP to its stand
· Lock the I-AMP onto the stand
· Measure the given distance from the base
· Place the mooring on the bottom
· Measure the given distance above the bottom
· Attach the velocimeter to the mooring line
· Collect two samples of eelgrass for topside analysis
· Transplant two eelgrass frames to a previously disturbed area
What follows is a summary of the electrical and fluid power requirements for the RANGER class. The complete design and building specifications will be included within the competition manual.
NOTE: Watch for new safety requirements and additional, detailed electrical specifications within the competition manuals.
SIZE AND WEIGHT POINT VALUES
The Applied Physics Laboratory at the University of Washington has included an ROV size and weight requirement in the request for proposals (RFP). Smaller, lighter vehicles will be given special consideration and vehicles above a certain size and weight will not be considered..
All size and weight measurements will include the vehicle, all tools and components, and the tether. The topside control system and 1 meter of tether going into the control system will NOT be included in the length or weight measurement. To receive points for smaller sized vehicles, the two largest dimensions of the vehicle and tether must fit through a round hole of the following dimensions:
|SIZE||SCORING||WEIGHT (in air)||SCORING|
|< 60 cm diameter||+20||< 12kg||+20|
|60.01cm to 75cm||+10||12.01kg to 17kg||+10|
|75.01cm to 85cm||+5||17.01kg to 25kg||+5|
Vehicles above 85 cm in diameter, or greater than 25 kg in weight, will not be allowed to compete in the product demonstration.
NOTE: In addition to the size and/or weight limitations described above, companies must be able to personally transport the vehicle and associated equipment to the product demonstration station and to the technical sales presentation room. The ROV systems must be capable of being safely hand launched.
Teams are permitted to use the materials of their choice provided that they are safe, will not damage or otherwise mar the competition environment, and are within the defined design and building specifications.
Teams are encouraged to focus on engineering a vehicle to complete the product demonstration tasks; when considering design choices, teams should ask themselves which one most efficiently and effectively allows them to solve the problem. Re-using components built by previous team members is permitted provided that the current team members evaluate, understand, and can explain their engineering and operational principles. Using or re-using commercial components is also permitted, provided that team members evaluate, understand, and can explain their engineering and operational principles. Teams will be questioned extensively on their overall design and component selections during their technical sales presentations.
The complete competition manual will be released by November 15, 2017; teams have from that date until the regional events in the spring of 2018 to construct their vehicles and prepare the engineering and communication components (technical reports, engineering presentations, and poster displays).
