Robots that know when something is wrong

problem

So how do you know when something is going wrong with your robot?

Step 1: You need instrumentation.

We have lots of sensors and instrumentation in OpenROV, but the raw data is just that, data. It needs to be interpreted to create information we can use.

Step 2: Interpet the data

After hundreds of hours of flying OpenROV, we have gotten a sense for when something is wrong with the ROV. But even though we know what to look for in the data, manually scanning a rapidly changing telemetry stream is hard.

This is what the raw data looks like when flying OpenROV.

Step 3: Have the robot do what robots do well, monitor the data.

In a tele-robotic system, it is asking a lot for a pilot to monitor a rapidly changing telemetry stream for data anomalies…

Win an OpenROV kit by telling us what you'd explore with it!

Over the past few months, we've quietly been building a better way for OpenROVers to meet each other and share their adventures, dives and expeditions. It's called OpenExplorer.

Many of you have seen recent trips and dives that we've linked to here on the OpenROV blog. Now we want to hear from you! We're going to be GIVING AWAY 5 OpenROV KITS* to the expeditions that gather the most amount of followers on OpenExplorer over the coming month (ending 12pm PST on 9/19). 

The key: you don't have to have everything figured out before you begin. Just get started!

We started OpenROV because we wanted to explore an underwater cave near our home. We didn't have any expensive equipment or a research grant, so we took a different route: sharing and collaborating with others who wanted to share the adventure.…
