A robotic fish has been spotted recently in the Kalamazoo River in the state of Michigan monitoring pollutants. The name of this amazing robotic fish is Grace. It was developed a few years ago by Xiaobo Tan, an associate professor at Michigan State University (MSU).
Xiaobo Tan and his team mates have now made a number of improvements on the robotic fish to improve its ability. As a result the robofish Grace has the ability to glide long distances through water using very low energy. Grace's ability to glide is controlled by a newly installed battery-powered pump that forces water into and out of its body. The sliding weight of its battery inside its fuselage changes the robot's center of gravity. As a result the robofish now can dive or surface on command.
The robofish Grace is now equipped with an array of sensors that allow it to travel autonomously and measure water temperature, quality and other pertinent facts. A steady stream of sensor readings can be sent to researchers over a wireless connection. In this way the robotic fish can gather valuable data that can aid in the cleaning of our lakes and rivers.
