Unformatted text preview: MIT OpenCourseWare http://ocw.mit.edu 2.00AJ / 16.00AJ Exploring Sea, Space, & Earth: Fundamentals of Engineering Design Spring 2009 For information about citing these materials or our Terms of Use, visit: http://ocw.mit.edu/terms . The Task Design and construct a remotely Operated Vehicle that can be used underwater for exploration with video capabilities and sensors for measuring environmental data. Constraints • Maximum dimensions of 50cm x 50cm x 50cm • Topside control via 15m tether with 12V DC power • Maximum of three motors • Submersible to a minimum of 20 ft. • Must have light bank, camera, and sensor package The Initial Design In order to maximize the chance of success, the decision was made to keep the design as simple as possible. We used a rectangular PVC frame with a 30 cm square base and 20 cm height. Extra beams were placed along the bottom and the top to serve as attachment holds for the motors and sensor package. Small holes were drilled in the PVC piping to increase the rate at which they flooded with water. Weights (objects with greater gravitational force than buoyant force) and floats (objects with greater buoyant force than gravitational force) were arranged to self-right the vehicle and counter any unwanted rolls or pitches. The three motors were placed near the bottom of the frame, two at the rear for x-y direction motion, controlled by three-direction switches in the control box at the surface. The lift motor was placed in the middle of the bottom of the frame and controlled by button toggles at the surface. The camera and two light banks were placed at the front. The sensor package was attached to the top, with a float of similar size attached opposite for balance....
