The Project
Dow Chemical currently uses drone technology to collect samples of chemicals from their
storage facilities. The drones collect samples from storage tanks that are tens of meters high.
This speeds up the data collection process compared to having a human collect them.
Dow Chemical is also interested in using drone technology to revolutionize the way we monitor
environmental phenomena. Toxic algae blooms are a major environmental concern since they
can cause health problems for humans and animals. Drones can collect sample data and
accurately locate them using a GPS system. This allows researchers to study the severity of the
algae concentration. Our task was providing a solution for collecting algae samples without
contaminating them and making sure they arrived safely.
Our sampling design has four rooms that will clamp under a drone. with the same mechanism in
each. A small motor connects to a shaft that holds a spool of rope. Each room has a small motor
that connects to a shaft holding a spool of rope. At the end of the spool of rope is a test tube
container that can carry 100 milliliters of water. A magnet attaches to the end of the test tube
container, and an opposite another magnet sits high against the wall of the container. An encoder
inside of the motor controls the amount of rope released, depending on how high the drone is
above the water. Once the test tube is dropped into the water 100 milliliters are collected. Then,
the motor winds the tube back into the container, where the magnets stick together. This prevents
the samples from moving during flight. This design can be used by various drone bodies by
changing the number of rooms that are attached.
This project explores the technology behind drone monitoring of algae blooms and the various
challenges associated with the process. Our design can help people track and respond to algae
blooms, which positively impacts environmental health.
Team
Five young, driven mechanical engineering students at FAMU-FSU have teamed together to tackle harmful algae blooms

Call To Action
Every year, millions of fish and other aquatic animals die due to complications of algal overgrowth. Creating a tool that allows for relatively easy and cost-effective sampling of bodies of water will allow these algal infections to be found and fixed sooner. These actions would preserve animal life as well as keep tourism strong for these coastal communities hit hard by algal blooms such as red tide.
