Platypus LLC STEM Careers Tour – Flood Gates of Collaboration

Platypus LLC and Grow a Generation STEM Careers Tour

Out of our sixteen tours, the tour of Platypus, LLC was my favorite. Platypus, LLC is a Pittsburgh based company that provides environmental monitoring solutions for water bodies using autonomous robotic boats. Pras Velagapudi, their Chief Technology Officer, was our guide.

Platypus LLC and Grow a Generation Distributive RoboticsHe started by explaining how Platypus used a combination of marine, electrical,  and software engineering to make their autonomous robotic boats. Marine engineering shaped the hull and kept the boat buoyant.  We had an opportunity to examine some of their recent designs created in house with vacuumed formed ABS plastic to form a four foot by two foot floating machine that has a fan on the top. The boat is only 8 inches deep deliberately built to make little environmental impact. The fan can be turned by the motor and controls the direction and propulsion. The design can be made larger or smaller and replicated to allow many robotic boats to work together collecting data.

Engineers used a smartphone as their onboard computer system as a simple used phone can be installed with software to perform monitoring work, serve as the wifi-enabled communication system, an inertia measurement system to measure velocity, orientation, and gravitational forces, and a GPS. The battery of the smartphone can be recharged and sent out for hours of operation at a time.

Smartphone technology was coupled with an Arduino and programmed with open source software for both the operation of the Platypus robotic boats and the data processing for whatever monitoring the boat is commissioned for. This software is available for download at www.github.com and uses Netbeans for GUI, Eclipse on a Nexus 7 Android phone and C+ + MakeFiles for its firmware.

Platypus LLC and Grow a Generation STEM Careers Tours Brain TrustsThe company was formed out of a CMU Robotics Research Group trying to test a platform for their autonomous interactive programming. The CMU roboticists had determined that there were too many obstacles on the ground and struggled to find a good power source for the air. Water robotics gave them the opportunity to avoid harmful collisions and utilize small amounts of energy. Platypus was founded when the roboticists learned of the potential markets and demand for autonomous boats with the environmental testing, fisheries, and flood water monitoring.

While some of their experimental designs were made out of styrofoam, composite materials shaped by vacuum molds were used to create boats Platypus needed to mass produce.

Since Platypus’ mission is to assist the environment, their intellectual property isn’t patented and is available open source. This allows anybody who needs the information to gain access to it, experiment and make changes to the systems as they require.
