  • Lasers are permitted provided that the team follows the specifications included within the competition manual. 
  • Camera is required.
  • Depth requirement at the international competition: 4.6 meters.
  • Maximum size: 75 cm. Vehicles above this size will not be allowed to compete in the product demonstration. See below for additional details on size and weight requirements.
  • New in 2017! Maximum weight: 20 kg. See below for additional details on weight requirements.


SIZE AND WEIGHT POINT VALUES

The Port of Long Beach 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
< 48 cm diameter +20 < 11kg +20
48.01cm to 54cm +10 11.01kg to 12kg +10
54.01cm to 60cm +5 12.01kg to 14kg +5

 

 

 

 

 

Vehicles above 75 cm in diameter, or greater than 20 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.

RESOURCES

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.

TIME
The complete competition manual will be released by November 15, 2016; teams have from that date until the regional events in the spring of 2017 to construct their vehicles and prepare the engineering and communication components (technical reports, engineering presentations, and poster displays).  Visit the MATE website at www.marinetech.org or request to be added to the MATE competition listserve to ensure a timely delivery.
