After a quick review of build specs and a visual inspection of contact seals, the robot stepped deeper into the water. Here the slope was steep and just a few more steps put them fully submerged. Soon the robot’s body had achieved equilibrium with the surrounding water and they were able to push off and drift over deeper sections that disappeared into the blue-green gloom. Despite criticisms received for similar exploits in the past, the robot felt the risk was worth the outcome: the curious effect on gyroscopes once neutral buoyancy had been achieved. The sensation of “floating.”
The robot sat on the edge of the dock, a structure made somewhat untrustworthy by time and environment. Tremendous inconvenience, not to mention possible water damage, shimmered under its dangling feet. It was precisely this probability that allowed the robot the focus on isolating signal from noise.
