    Product: Water Sampling Robot
    Environmental Impact: Monitoring the levels of biochemicals in the water 
    Planetary Boundary: Ocean Acidification, Freshwater Use 
    Keywords: Ocean monitoring, Marine environment, Oceanic data collection, Water samples, Freshwater Use, Marine Robotics, Autonomous underwater vehicle, Preventive solution
    Description: Autonomous water sampling technologies could help to monitor biological threats to freshwater ecosystems as well as filter and preserve the captured material once identified. Originally adapted from a marine environmental sample processor (ESP), this experiment found that this device was as effective as manual sampling methods.

  • Row-bot: An energetically autonomous artificial water boatman
    IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), December 2015
    Product: Marine Robot 
    Environmental Impact: Reduce carbon emissions 
    Planetary Boundary: Climate Change, Ocean Acidification
    Keywords: Biomimetics, Marine Control, Microbial fuel cells, Bio-inspired actuation, MFC-powered swimming robot, Water boatman beetle, Ocean cleaning, Ocean acidification, Freshwater Use, Marine Robotics
    Description: This research paper presents a design for an energetically autonomous artificial organism that demonstrates the anabolic, propulsive, and feeding mechanisms of an artificial, water boatman-inspired organism marine robot. The work is the demonstration of energetically autonomy in a microbial fuel cell (MFC)-powered, swimming robot taking energy from its surrounding aqueous environment.  The energy generated has been shown to exceed the energy required to refuel. Biomimicry of the water boatman beetle has driven key design features resulting in system optimization including morphology to suit the drag profile required for power and recovery propulsion phases and combined floatation and oxygen supply.
