Video from the final flight of our Tahoe III expedition. This was a 2.7 that we were testing out. We discuss what is new in the video. We have some issues with weight due to the 2.7 being lighter than prior models. Once we fix that we give you a great video showing why you want floats on your tether with rocky terrain.
This is video from the 2nd flight of day 1. Using a 2.7 chassis and trying out an experimental camera to get comparison video. We end up with lots of "HUD Reboots" which are actually a result of the Arduino rebooting. Later troubleshooting narrows this down to use of the IMU. Additional troubleshooting needed.
We have night life in the water. This is video from our night dive on day 1. This is using the screencast plugin for Chrome to do the recording. We have a second video which is the same feed but using another program. Our plan is to compare the two so we can make recommendations on which to use.
This was using a stock 2.6 with a poorly mounted go-pro on the front that served more as bumper to keep off of the rocks.
Our first dive was using a 2.6 unit. Our goal was to get reference video so that we could compare the quality of video between units. As the first flight, we spend some time correcting the angle of the wireless system to prevent communication brown outs. We did git a quick video of a fish. We run most of the flight with the latest depth hold code enabled.
This evening, we decided to do a preliminary dive with a few ROVs in the pool near the house we're staying at. Some passer-byers saw the ROVs in the water and stopped by to take a look, then a few more came, then more still. Before we knew it, the whole pool was lined with onlookers as we flew the robots around!
On the way to Tahoe. We have a 3 car caravan and a 3 hour drive...
From a software standpoint we have several things to tests:
1) Depth and Heading control loops that we would like to dial in.
2) Would like to log a good 20 minutes of open drive time using drive by wire.
3) Real time performance tuning. Use the telemetry data and new diagnostics data to paint a more complete picture of what the ROV is doing.
