Marine Debris Cleaner BY RYAN FABRE AND BROCK DICKINSON

Marine Debris Cleaner Sea-debris is extremely threating to aquatic life and ecosystems Example: Death of the Great Barrier Reef Purpose: to reduce the amount of garbage in our oceans The progress of the project will be measured by how much garbage will be collected Target: Plastics

Computation The computation used in the project will be ran on a raspberry pi controller The controller will: Control navigation limits Keep track of location using preloaded mapping software Control the two arms for debris retrieval Capable of doing up to two functions at once Control the servos and actuators Use arrays to keep track of mechanical components

Navigation Will use an object-oriented language Ex: Python Uses visual guidance and geoguidnce The navigation system will use markers Distance will be calculated using nautical miles Multiple variables like wind speed, high, and low tide will be important Navigation will be done in real-time

Debris Retrieval Mechanism Consists of two arms One arm will be used to collect debris The second arm will be used to store debris Moves at a low velocity to ensure that the system is friendly to marine life Actuators will be the main components for changing the angle of the arms Motion Sweeping motion

Components 1 to 2 actuators: they will control the angle of motion in the arms 1 Raspberry pi 3: will act as the controller 2 Robotic arms: one arm will be used to collect debris and the other will be used store debris 1 Sail: The sail will be used assist in moving the vessel 2 Propellers: Will be the main source of movement 1 Wind sensor: Will read the wind speed and direction 2 Servos: Will fit between the arms 1 Solar Panel

Constraints: Energy Conservation Availability of Materials Budget Testing Environment

Pros and Cons of Using a Sail: Pros: Helps to conserve energy Offers a large number of possible implementations Inexpensive Cons: Only usable when winds are strong enough Difficult to implement into the design due to solar panels More susceptible to damage

Pros and Cons of Using Propellers Pros: Offers better control for steering Provides more power Works well in conjunction with other components Cons: Use more energy Requires a motor Limited number of design implementations

Schematic

Deliverables The debris cleaner will be able to float The navigation system will be fully functional The cleaner will be able to sustain enough energy to move from point one point to another and back The debris cleaner’s arms will move in a sweeping motion The test area will be completely cleaned based upon the amount of debris collected Complete prototype Finalize the design
