SAMPLE is a Small Autonomous Monitoring Platform for Lakes and Estuaries. SAMPLE was designed andbuilt using easily accessible materials and fitted with different sensors and electronics to allowautonomous navigation and data collection. It is an under-actuated (rudder) Surface AutonomousVehicle (SAV). Forward motion is provided by an air propeller. Heading control achieved by directing airwith a rudder. The rudder is partially immersed in water for better sensitivity. Proportional andProportional-Integral-Derivative (PID) control of the heading is achieved using GPS and compass sensorfeedback, which are connected to an NXT Lego brick which serves as a microcontroller. Various waterquality sensors that are incorporated in the SAMPLE platform include temperature, pH, salinity, anddissolved oxygen. SAMPLE is easy to use and transport. It offers a cost-effective way of monitoringselected geo-located water quality variables to provide insight into coastal ecosystems. It is also anexcellent platform to expose engineering students to mechanical design, instrumentation, and controlsystems. The SAMPLE platform was designed and developed by engineering students at University ofMaryland Eastern Shore. The engineering students have also demonstrated and trained Marine Botany(Biol 202) students at the university to collect and map water quality data in lakes and ponds insidecampus, as well as bays and estuaries nearby.
