Bob Hsiung's Design Portfolio

The Nuclear reactor pressure vessel inspection robot is designed to inspect the bottom of a hemispherical pressure vessel for structural flaws. The robot clamps onto the vessel with magnetic wheels and can navigate between the grid of pipes which emerge at non-perpendicular angles from the vessel surface.

The robot is equiped with a video camera and an ultrasonic sensor. The sensor is mounted on a multi-axis gimbal at the front of the robot. The robot is rear-wheeled steered for maximum positioning capability of the sensor.

I wrote the SBIR grants which funded this project through the first and second phases. I managed the project, designed, constructed and tested the robot.
