Thruster modifications

The custom VideoRay thruster cap was finished today. The standard configuration VideoRay thruster mounting bracket relies on the thruster to be mounted directly to the side of a pressure vessel, allowing for the power cables to pass into the pressure vessel. Because our mounting location for the thruster was not against a pressure vessel, and the length of the plastic endcap was unnecessary, we decided to create a custom end cap which would facilitate the cables to pass through the sealed cap. Pressure testing on the cap tomorrow, then full production and anodizing!

Update: We completed the pressure testing of the new endcap and it performed as expected. The final assembly of the SEACON cable in the new endcap is also pictured. Next step, send to anodization with the rest of the parts!

Update 2: Seabotix endcaps have been modified to fit our custom cables by removing the potting urethane. Both the custom VideoRay endcaps and the modified Seabotix endcaps will next be potted with urethane to guarantee waterproof performance.

Update 3: The Seacon cables have now been potted into the thruster caps. Everything is pressure tested and watertight.

About Us

The Machine Intelligence Laboratory (MIL) provides a synergistic environment dedicated to the study and development of intelligent, autonomous robots. The faculty and students associated with the laboratory conduct research in the theory and realization of machine intelligence covering topics such as machine learning, real-time computer vision, statistical modeling, robot kinematics, autonomous vehicles, teleoperation and human interfaces, robot and nonlinear control, computational intelligence, neural networks, and general robotics. Applications of MIL research include autonomous underwater vehicles (AUVs), autonomous water surface vehicles (ASVs), autonomous land vehicles, autonomous air vehicles (AAVs including quadcopters and micro air vehicles, MAVs) , swarm robots, humanoid robots, and autonomous household robots.

MIL’s SubjuGator is the three time champion autonomous submarine of the RoboSub AUVSI/ONR underwater competition (2005-2007), and placed in the top 3 in eleven of the 21 years of the competition (including second place in 2012, 2013 and 2014). MIL’s NaviGator AMS, is the defending champion in the Maritime RobotX Challenge (from our victory in our only entry in this biennial competition in 2016). In 2013, MIL participated for the first time in the RoboBoat AUVSI/ONR water surface vechicle competition with our PropaGator robot boat; we won! In 2014, we earned second place in the RoboBoat competition. We also won the static division of the 2011 ION Robot Lawnmower competition with MIL’s InstiGator robot lawnmower.
