MCPLP Robotics Video Survey

(Mill Creek Park Lakes Project)



MCPLP will endeavor to build and deploy low-cost, open-source underwater robots to perform a video survey of the bottom of Lakes Glacier, Cohasset, and Newport. These convenient natural resources offer an excellent opportunity to explore and possibly innovate underwater robotic applications. We believe that a total underwater video survey (using robots) of the bottom of our precious lakes has never been done before and will serve as a interesting and fun project for robot enthusiasts, students, and researchers in the area. The artifacts of this project will be accessible to the Northeast Ohio Community.


 

Challenges of Underwater Robots


Underwater robots can be used to monitor, perform or assist in performing water quality assessments. Underwater robots can be used to deploy sensor clusters or long term monitoring devices (like data loggers). 

Underwater robots can:

  1. Access areas that are impossible or difficult to access

  2. Allow for more routine assessments/monitoring for longer periods of time

  3. Be used to gather information about the physical characteristics of the body of water


Here are some of the challenges we must meet:


  1. Underwater Communications

  2. Sound waves in shallow water can be adversely affected by temperature; electromagnetic waves do not work due to the conducting nature of the medium; free-space optical waves used as wireless communication carriers are generally limited to very short distances.

  3. Power Levels

  4. High power levels are needed due to more complex signal processing

  5. Positioning Measurements

  6. Challenge of obtaining precise positioning. GPS fails to provide location and time information (Use of Multiple GPS Intelligent Buoys - GIBs).

  7. Mid-Depth Zone Navigation

  8. Mid-depth zone severely limits the navigational and exploration capabilities of the robot. There are not sufficient commercially available sensors that can work at this mid-depth for precise and accurate measurements.

  9. Unpredictable Disturbances

  10. Environmental disturbances due to weather changes, waves, wind, and ocean currents have a significant impact on underwater robot motion and stability.

  11. Visual Imaging
