In May 2019 I posted a news on Gladius Mini, an underwater drone targeting the mass market at a price point around 1,400$ US, The same company is now pushing the envelope with a smaller model, Dory, they plan to offer at a 500$ price point hoping to hook a much broader market. The appeal lies both in the much lower price and in the smaller form factor with only one equipment needing charging, the drone itself that powers the wifi buoy it is tethered making for easier charging.
For a full review, and comparison with its pricey sibling, take a look at the clip.
The company has opened a Kickstarter campaign that was going really well at the time I took a look. They were aiming for a 27,000$ goal and they had already received pledges for over 133,000$.
Apart from being an engaging gadget for people liking the undersea world it extends our each to the liquid element and the company in its advertisement explicitly mention the seamless connectivity to social networks. You can take HD video and still photos that can be uploaded to the smartphone phone and from there post them to the world.
It is also interesting to see that the smartphone has become the usual control device for drones, aerial as well as underwater (in this latter case there is the need for a buoy acting as wifi bridge since WiFi signal cannot go under water).
The Dory does not seem to have any autonomous spirit, it is completely controlled via the smartphone. On its screen you can see what the drone camera sees and decide how to move it around. It has control feedback that makes steering quite easy. As an example you can decide to have it hovering (can you hover underwater?) in front of a coral reef or a school of fish and Dory will take care of counterbalancing currents to effectively stand still in that position.
