26 st / December 2017 ings performed flawlessly throughout the competition and were able to help the FAU Marine Robotics Club complete the underwater scan challenge in Virginia. There was also a winch built to launch and recover a Vid- eoRay ROV for RobotX. This winch, however, was not able to be tested under full load. The 3D-printed part that cou- pled the spool and motor shaft was not able to handle the forces being applied to it and thus needed to be remade as a CNC aluminum part in order to handle the load. The other use of the full-ceramic bearings that worked very reliably T he Marine Robotics Club is a registered student organi- zation at Florida Atlantic University (FAU) whose main focus is giving students a hands-on experience with robotics in the maritime environment. This includes the design, fab- rication and testing of autonomous systems designed with certain competitions in mind. Located in south Florida, FAU is the perfect setting for programs centered on marine engineering and robotics, as it is located just miles from the Atlantic Ocean. Working in saltwater environments poses its own set of unique circum- stances and challenges that students learn to work with and overcome. These competitions are designed to mimic current in- dustry and military applications of marine robotics, such as port security, oceanographic operations and coastal surveillance. The club currently designs vehicles for the RoboSub, RoboBoat and RobotX competitions. Boca Bearing has been a huge help in recent times in preparing for these contests as there are so many places where these vehicles require both bearings and lubricants. In addition, these vehicles are always heavily exposed to saltwater, which can mean traditional metal bearings may lead to reduced life spans of various sub- systems of the vehicles. Boca Bearing was a sponsor of both RoboBoat 2016 and RobotX 2016. These competitions were held in Virginia Beach, Virginia, and Ho- nolulu, Hawaii, respectively. Bearings The marine robotics club has used Boca Bearing full-ceramic bearings for different applications. For Ro- boBoat 2016, the team used Boca bearings inside a mostly 3D-printed winch system to launch and recover a small ROV. These bearings worked well since it was a low-load applica- tion with a need for a highly corro- sion-resistant bearing.
