Underwater Remotely Operated Vehicle (2012-2013) Introduction of members and project. UNH ROV is an on going project for the research of graduate students in the ME department. Galen Farrar & Jonathan Crockett

ROV Team Captain - Spencer Yergeau – ME, Propulsion Treasurer - Chris Brown – ME, Chassis Other Members - Galen Farrar – EE, Propulsion - Graham Conforti – ME, Propulsion - Jon Crockett – EE, Propulsion - Dean Goodale – ME, Propulsion - Stephen Griffin – ME, Chassis - Scott Champagne – ME, Chassis - Peter Oliver – CE, Controls - Boris Yakubenko – CE, Controls - Derek Dupuis – CS, Controls - Greg Warner – CS, Controls - Lane O’Connor – ME, Chassis There are students from four different departments – ME, EE, CE and CS. We have 13 members and our captain is Spencer Yergeau, a senior ME. This is last year’s CAD model of their ROV.

MATE Competition Marine Advanced Technology Education 2013 ROV Competition National Competition Design and build an ROV submarine that can maneuver underwater Official Tasks not yet released by MATE (expected in November) Power consumption limit also not released No weight limit Anticipated main tasks: Underwater maneuvering Use of pump to extract ‘oil’ from a fake oil spill Use of a mechanical arm Points awarded for maneuverability and task completion time Seattle, WA – June 2013 Our task is to build a remote controlled submarine that we will enter into the MATE competition in June. The specific events of the competition will not be released until November but based on previous years we have a pretty good idea what they might be. There are also limits on power which will also be released in November. Points are awarded for how successfully the sub can complete the tasks and there are points given based on design. The sub must have a camera on it because the person controlling it must do it only by video feed. Modifications will be made based on what the tasks end up being. Image: http://www.divetechltd.ca/

Design Teams Propulsion Controls Chassis Six degrees of freedom Six propellers Design and build thrusters Circuit design & fluid dynamics Controls C programming language Sensor system to determine oriention Playstation 3 controller Software engineering Chassis Frame resistant to corrosion Slightly positive buoyancy Waterproofing electrical capsules Static and Fluid Dynamics The propulsion team is made up of EEs and MEs. The basic goal is to design and build propellers in a system to allow high maneuverability in the water. The propulsion team will work very closely with the other two teams as well. The Controls team is CSs and CEs. Their task is to design a control system that will allow easy control of the submarine using a PS3 controller. An Arduino microcontroller and a Beagleboard will be used to allocate power to each propeller when necessary. The Chassis team is made up of MEs. Their goal is to design and build the frame of the sub. It needs to be lightweight but resistant to corrosion. They are also responsible for waterproofing the elecronic capsule.

Propulsion Team Design and implementation of 6 thrusters with propellers Power consumption concerns Work closely with Chassis & Controls Chassis team to determine thruster placement Controls to determine power allocation Sensors Four Sensors with accelerometers to determine movement Data analyzed by Beagleboard, Arduino allocates power Slightly Positive buoyancy In case of mechanical malfunction ‘Neutral’ state will have to be top propellers on We are both members of the propulsion team. Our main concerns are power consumption and integrating the thrusters with the control system. We will be using a four-sensor system to determine the submarines orientation and the controls will allow the propellers to respond appropriately. We would like the sub to have slightly positive buoyancy in case of a mechanical failure. Therefore, in order to keep the sub at a steady depth, the top propellers will need to be on.

Finance Fundraising Financial Assistance Sponsorship Packet Team Visits Financial Assistance UNH Departments Office of the Dean This is last years expense report. We are still working on our overall budget but we are looking at a total expense budget of around $24000. This includes all travel expenses to the competition. We have contact with several of last year’s sponsors and have sent them and other companies sponsorship packets, explaining the terms and conditions of sponsoring our project. We will also receive money from all four departments.

Facilities Majority of work in Chase Ocean Engineering Laboratory Wave tank & Engineering pool Work bench Machine shop Prototype Chassis Final Chassis Computer lab Controls development Our main laboratory will be in the Chase building. There we will be constructing and testing the sub. The chassis team will spend some time in the machine shop making mock up frames and eventually the final one. The department computer labs will also be used for design and research purposes during each phase of the design process. Images: http://www.unh.edu/oe/facilities/
