15 January

Today we had a fourth great day of robot systems tests. We also had a small crew from the Discovery Channel visiting for the last two days and grabbing video, and a professional subsea videographer who accompanied us underwater.

Over the last couple of days we operated the robots from shore. This included the first serious open-water untethered test of the robot, and additional walking data on different kinds of terrain type.

The second Aqua-series robot was deployed untethered underwater today, and was controlled using hand gestures, visual servo control, and bar codes. Our collaborators from York university used the same boat dive to collect underwater stereo vision data.

We had a few problems, which is on par for this kind of field trip. This included one person with a minor injury, and a one experiment that didn't work out. As I told my students, if every experiment worked perfectly, we didn't get close enough to the line.
