Technology review Chasing Dory

Chasing Dory is a cute name for an ROV. ROVs or remotely operated vehicles focused on exploring underwater. Drones are also a form of ROV, but drones are normally associated with flying above you in the air. Or next to you in the case of a selfie drone. ROV”s as the market defines them today work underwater. Many include a handset to operate them, and some use your tablet or cell phone.

Chasing Dory is much smaller (just over 3 pounds) and comes in a brilliant yellow. The base system includes a 150-foot teether and a buoy. What that means is you can go down 150 feet if the body of water is that deep!

  1. Wifi doesn’t work through the water. It works above the water, but once you start moving below the water level, wifi signals dissipate quickly. So with a drone in the air, you can use WIFI because WIFI works up to 10000 feet away from the receiver. With an ROV underwater, the device has to be tethered. Chasing Dory is a new system that has a tether, but the tether connects to the wifi-enabled buoy.
  2. These ROVs can go easily as deep as 1000 feet. However, the recommended depth is around 300 feet. Remember that water pressure is quickly greater than air pressure.

Chasing Dory has a set of headlights that allows the camera to see below water level. It takes a couple of times using an underwater ROV to get the orientation. Where Drones are a little less control specific, you have up, down, and side to side. With the ROV you have the same up, down, side to side, but the reality is you can’t physically see the ROV underwater. So what you see is what you are responding to with an ROV.

We haven’t had a chance to put Dory in the water yet. That will come after the end of winter! It is hard to operate controls when you have to wear gloves!

Chasing Dory has a nice software package, for either Android of IoS devices. The system can operate around 200 feet away from your phone. What that means is that the buoy, with Dory can be placed in the water, and then you can move your boat away from the area. You will get to see more without the shadow of a boat overhead!

I won’t do a rating for this ROV until I get it in the water and see what they video and still, pictures look like.

So, for now, it is an introduction review!
