Michigan State University researchers are spawning robot fish to monitor the quality of lake water and the effect of harmful algae.
An electric charge in the 9-inch MSU prototype causes its polymer fins to bend so the robotic perch can maneuver. Designs call for onboard sensors to record temperature, oxygen, pollutant, and algae data, which would be relayed to a docking station when the fish surfaces. GPS systems and infrared sensors could be developed to aid navigation.
The fish are … Read more
