Hello, this is Eduardo from SeaDrone.

On behalf of the SeaDrone team, I’m going to introduce our newest vehicle, the SeaDrone Inspector 3.

Behind the scenes of Inspector 3

But first, let’s go back to 2015 when SeaDrone shipped its first Inspector vehicles. They were the first vectored micro ROVs that you could launch and master in minutes.

The Santa Clara County’s search and rescue team showed us the need for the Inspector vehicles. The team experienced major problems with small underwater inspection vehicles because they were always getting swept downstream in strong currents. The team had to upgrade to larger ROVs that cost hundreds of thousands of dollars to accomplish their missions.

This problem inspired us to ask: how could we design a compact and affordable vehicle for local police departments? How could these ROVs perform on par with the larger vectored ROVs in crosscurrents? Answering these questions led us to launch the Inspector vehicles.

After the original Inspector ROV, we released Inspector 2 in 2017. The aquaculture and maritime industries adopted Inspector 2 to inspect fish farms and ship hulls. They love Inspector 2 because of its performance in currents and increased stability which offers operators superior footage.

Introducing Inspector 3

As the next step in SeaDrone’s evolution, I’m proud to announce Inspector 3. Before I walk you through Inspector 3’s design, let me share the reason we built the Inspector 3. We want SeaDrone customers to maximize their vehicle uptime in the field. This means protecting your assets and truly owning your vehicle.


Imagine you’re an offshore operator. You are about to perform an inspection and you discover that an abandoned rebar struck one of the propellers on the previous shift. When you’re stuck 80 miles from home, and there is no service center nearby, this damage can waste a whole day.

Now, imagine you have a toolkit in your pocket to handle repairs. You fix the problem, and the ROV is back in the water within minutes.

How would cutting out unexpected downtime impact your business?

Inspector 3 was engineered to be reliable and smart.

There are many sensors on the robot, including humidity and leak sensors.  The system continuously monitors the internal pressure of the electronics housing to ensure that it is water-tight. The smart battery management system is continuously monitoring for short-circuits and over-current.

The batteries charge in one hour. The batteries are portable so you can carry more than one pack in the field. Plus, it takes less than 1 minute to switch out the batteries.

If debris gets stuck in the propeller, many robots will keep going and destroy the motor. Inspector 3 will know it has stalled or that it is consuming too much current for its current speed and shuts down to avoid motor damage.


There is a full HD camera with 5000-lumen lights to produce high-resolution footage. The gimbal mechanism in the camera stabilizes the footage. The vectored thrusters ensure the Inspector 3 will hold its ground even in the strongest currents.

We integrated all the electronics onto a single board. Because we redesigned the vehicle from the ground up, we engineered a vehicle that is leaner, more efficient, and easier to maintain.

We continue to assemble and test every vehicle in-house to ensure the highest quality. Our team is proud of the design and workmanship that goes into every vehicle that leaves our factory. Inspector 3 continues in this tradition.

So, where does that leave SeaDrone in the marketplace of underwater inspection vehicles?

Our vision is to create a vectored ROV that performs at the same level as Saab's and Seabotix's in choppy waters but comes in a smaller form factor. To achieve this vision, we are using state-of-the-art electronics in the robot, mobile device software, and many years of experience in subsea vehicle design to enable Inspector 3 to excel at key tasks, such as inspecting tight spaces and the ability to operate within minutes of deployment. Most importantly, single operators can maintain and repair SeaDrone vehicles in minutes rather than hours or days. This goal of 100% uptime is a game changer for operators who rely on SeaDrone for their business every day.

We are very grateful to our early adopters who supported us throughout our journey. We have learned so much from these loyal customers. You told us that it’s not good enough to have a robot that simply runs. You wanted a robot built to last for years and a robot that you can own inside and out.

So, do we have what it takes to satisfy these customer needs? Well, even though the bar is very high, I think we’ve achieved it. We started shipping Inspector 3 on February 5, 2019. And I am personally so excited about Inspector 3.
