Project
Overview
The goal of this project is to design a platform for a Didson 300m, a high resolution mutlibeam acoustic camera. The system will be used to observe marine biology off the coast of Maine. It will provide a practical and stable viewing platform against a strong current on an uneven ocean floor. The platform will have adjustable legs enabling it to provide a level surface. The camera will also tilt 90º allowing for both horizontal and vertical position detection of the fish. Below is a preliminary CAD drawing, using SolidWorks, depicting a tripod with pneumatic linear actuators to level the platform on uneven surfaces. A ballast tank located below the camera and mount, will allow the platform to be easily taken in and out of the water. The picture to the lower left shows the completed platform with dummy camera. The Midterm Report gives an overview of what's been accomplished as of December 2011.
When
the spring semester began, we hit the ground running. The drag data
testing can be found on the Testing link at the top of the page. Once
that was completed, we focused on the design and fabrication of the
mount. The IMU program was completed once the mount was put together
and was operational during the Crosby Lab Open House on April 26. The Final Report gives a detailed look at what was accomplished this year. View the Instructions Manual to see how the mount is to be operated.
