尽管四旋翼无人机已成为主流，但水下同类产品却不能说相同。可以说，与想从天空中捕捉世界的人们相比，寻求水下拍摄的人们更少。但是，那些想要这样做的人有一些有趣的选择，例如 M2 ROV。
While quadcopter drones have long gone mainstream, the same cannot be said about their underwater counterparts. Suffice to say, there are way fewer folks looking to film underwater compared to those who want to capture the world from the skies. Those who want to do it, though, have some interesting options. Case in point, the Chasing M2 ROV.
这不是与您的朋友在海滩上闲逛的爱好级水下无人机。水下ROV（远程操作车辆）面向专业用户和工业应用，其构造和价格点对于探索海底深处秘密的发烧友而言非常可行。
No, it’s not a hobby-grade underwater drone for goofing around on the beach with your friends. Instead, the underwater ROV (remotely-operated vehicle) is geared towards professional users and industrial applications, albeit in a build and a price point that actually makes it quite viable for enthusiasts looking for affordable ways to explore the secrets that lie beneath the ocean’s surface.
Chasing M2 ROV使用八个独立的推进器，每个推进器以不同的角度安装，从而使该设备实际上可以在任何方向上移动，以实现360度的可操纵性。从向前和向后移动到上升和潜水，再到向任意方向滚动，倾斜和转向，此功能使您可以即时切换方向，而无需执行复杂的操作即可将其移动到想要的位置。可以说，当无人机在水下滑行时，如果您在实时看到一些有趣的东西，您可以立即向其方向发送。
The Chasing M2 ROV uses eight individual thrusters mounted at different angles each, allowing the device to move in, practically, any direction for full 360-degree maneuverability. From moving forwards and backwards to rising and diving to rolling, tilting, and turning to any direction, this thing allows you to switch directions on the fly, with no need to execute complex maneuvers to get it where you want to go. Suffice to say, if you see something interesting in the real-time feed as the drone glides underwater, you can immediately send it towards its direction.
这些推进器采用了“防卡死技术”，据称，这种技术可大大减少吸入沙子，海藻和其他碎片（水下无人机的常见问题）的可能性，因此您无需进行任何操作即可探索水域。这款无人驾驶飞机应该能够应对任何复杂的水下环境，无论是繁荣的珊瑚礁生态系统，沉没于18世纪的海盗船，还是一个史前怪物居住的宁静湖泊。
Those thrusters are designed with the outfit’s “anti-stuck technology,” which, they claim, greatly reduces the likelihood of sucking in sand, seaweeds, and other debris (a common problem with underwater drones), so you can explore the waters without having to deal with such annoyances on a regular basis. Because of this, the drone should be able to handle any kind of complex underwater environment, whether it be a thriving coral reef ecosystem, a sunken pirate ship from the 18th century, or an erstwhile quiet lake supposed to be home to one prehistoric monster.
Chasing M2 ROV具有Sony CMOS传感器，可以以152度视角以30 fps拍摄12百万像素的照片和4K视频。两组2000流明的LED灯为框架提供了所需的照明，确保您可以使用完整的色彩和细节清晰地捕捉水下场景。它可以将素材直接流式传输到安装在附带的遥控器（类似于空中无人机）上的智能手机或平板电脑上，并将其保存在固定在无人机内部的可移动SD卡（最大512GB）中。
The Chasing M2 ROV has a Sony CMOS sensor that allows it to shoot 12 megapixel photos and 4K video at 30 fps with a 152-degree field of view. Two sets of 2000-lumen LED lights provide the needed illumination for the frame, ensuring you can capture underwater scenes clearly, with full color and detail. It can stream the footage directly to a smartphone or tablet mounted on the included remote (similar to an aerial drone), as well as save it on a removable SD card (up to 512GB) docked inside the drone.
只需按一下按钮，无人机即可悬停在其范围内的任何深度，从而使您可以长时间专注于要观察的对象。功能包括最大3节的速度，长达四个小时的运行时间（如果不断移动，降到两个小时），可更换的电池模块 ，最大潜水深度为328英尺，最大为650英尺的缠绕绳，以及一系列可选附件，最大重量3.3磅，包括机械手爪，激光洁牙机和用于单独摄像头的支架。
The drone can hover at any depth within its range at the push of a button, allowing you to focus on a subject you want to observe for extended periods. Features include a maximum speed of 3 knots, up to four hours of runtime (though it can go down to as short as two hours if it’s constantly moving), swappable battery modules (you can change batteries and drop it right back in the water), maximum diving depth of 328 feet, up to 650 feet of winding tether, and a range of optional attachments up to 3.3 pounds, including robot claws, laser scalers, and mounts for separate cameras.
Chasing M2 ROV现已上市，售价为2699美元。
The Chasing M2 ROV is available now, priced at $2,699.
