SR-1 First In-Water Tests

I am very proud of our team at Square Robot for meeting an incredible milestone. In just over 12 months they built and launched an autonomous robot for tank floor inspections.

In Mid-December, the Square Robot Team launched SR-1 in water for its first time! After just three days of comprehensive system and sensor testing, the team reached for and achieved their stretch goal: self-alignment of the internal navigation system. Special thanks to the MIT Sea Grant Laboratory for use of their facility.

More recently, on January 2nd, we advanced to the second phase of in-water testing. For this stage of testing we set up at the University of New Hampshire’s Ocean Engineering Lab. Heavy snow and cold weather helped us hunker down, focus, and get all our work done over a three-day period. We used the extreme outdoor temps (-20F) to cold-soak the robot for several hours and then bring it back to room temp for an immediate immersion test. All systems passed. During this round of testing, the team spent significant time gathering navigation and sensor data and refining motor controls for hovering and track-line following.

We are back at UNH this week for testing before moving the vehicle to Houston where we begin work at Delta Subsea’s above ground test tank. On January 25 and 26 we will be hosting demonstrations at Delta’s facility in Houston.
