There is a new underwater photographic robot fish in underwater photographic equipment. Have you ever filmed it? JD.COM zhongchoushang

Looks like the Peking University team did it, right? The disadvantage is that the battery life is short and the dive depth is only five meters. In my opinion, it is a toy at best! I tried it on the spot before, and the experience was not good.

There are several factors that must be considered when buying an underwater robot: dive depth/shooting configuration/battery life.

diving depth

Do you have to dive at least tens of meters to film marine life or divers? And the influence of current. This underwater robot fish is propelled by swinging its tail, which is slow and unstable. And only five meters deep! Just play in the swimming pool!

Shooting configuration

I searched a similar underwater robot Gladius for comparison, which can shoot 4K and 1080P videos. The higher the resolution, the finer the picture quality. So I won't consider the underwater robot fish with low configuration.

3. Battery life

It is also a built-in battery. The battery life of the underwater robot Gladius is 180 minutes, while the battery life of the underwater robot fish is only 50 minutes. I don't know if it is to reduce the battery storage in order to make the fuselage lighter. But ... what can you shoot in 50 minutes? Will the battery die after playing for a while ... As a consumer, I hope to have fun as much as possible, instead of charging for playing for a while.

Consumer underwater robots usually cost thousands of dollars. I have seen the underwater robot fish raised by JD.COM, and I don't plan to buy it, because it is not cost-effective. However, Gladius, an underwater robot that will be crowdfunding in Indiegogo next month, will cost only 4,000 RMB for the first wave of early birds. Cost-effective.

Finally, talk about crowdfunding. The crowdfunding of underwater robot fish in JD.COM is tied to some surrounding areas (such as T-shirts). It feels a bit like compulsory consumption. I just want to buy an underwater robot, and I don't need some useless things.
