EXPLORER Missions

DESIGN BRIEF

Commerce: Hyperloop Construction

  • Insert two rebar reinforcement rods into position in the steel baseplate. 
  • Install the frame onto the baseplate.
  • Remove a pin to release the chains holding the frame.
  • Transport and position the hose for pouring concrete into the frame.
  • Retrieve the three positioning beacons and return them to the surface


Entertainment:  Light and Water Show Maintenance

  • Disconnect the power cable from the platform.
  • Turn the valve to stop the flow of water to the platform.
  • Disengage the locking mechanism at the base of the fountain.
  • Remove the old fountain.
  • Install the new fountain.
  • Re-engage the locking mechanism at the base of the fountain.
  • Turn the valve to restore the flow of water to the platform.
  • Reconnect the power cable to the platform.
  • Return the old fountain to the surface, side of the pool.


Health: Environmental Cleanup

  • Use a simulated Raman laser to determine if contaminants are present in two sediment samples.
  • Collect a 100 ml sediment sample from the contaminated area and return it to the surface. The sediments will be simulated by agar.
  • Collect two clams from the contaminated area and return them to the surface.
  • Place a cap over the contaminated sediments.


Safety: Risk Mitigation

  • Locate the four cargo containers.
  • Activate each container’s Radio Frequency IDentification (RFID). This will be simulated by shining a light into a port on the side of the container to activate the sensor.
  • Obtain RFID data via Bluetooth.
  • Use the data to determine the container’s identification number, contents, and if the contents are high risk. (MATE will provide you with a container manifest.)
  • Attach a buoy marker to the eye-bolt on the container with high-risk cargo.
  • Determine the distance from the high-risk container to the other three containers.
  • Determine the direction from the high-risk container to the other three containers.
  • Use distance and direction to make a survey map of the incident site. (MATE will provide a blank map with 0.25 meter squares.)

 

SPECS

What follows is a summary of the electrical and fluid power requirements for the EXPLORER 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.

  • New in 2017!  48 volts, 30 amps DC. Conversion to lower voltages must be done on the ROV, not topside. Onboard electrical power is not permitted.
  • Pneumatics and hydraulics are permitted provided that the team passes the MATE Fluid Power Safety Quiz and follows the specifications included within the competition manual.
  • Lasers are permitted provided that the team follows the specifications included within the competition manual.
  • Camera is required.
  • Depth requirement at the international competition: 3.7 meters.
  • New in 2017!  Maximum weight: 25 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
< 58cm diameter +20 < 17kg +20
58.01cm to 64cm +10 17.01kg to 19kg +10
64.01cm to 70cm +5 19.01kg to 22kg +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.

 

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.
