Four-thruster concept

Directional control with a focus on simple, familiar piloting.

Camera-first design

Live underwater imagery at the centre of the experience.

Modular by design

Replaceable parts, with room to explore new capabilities.

The engineering idea

Pressure-balanced electronics and a repairable frame could bring costs down. Depth, endurance and production economics still need physical validation.

The surface is
the connection.

A compact companion for the cable, the connection and the next dive.

The surface hub concept brings together the tether connection, local Wi-Fi and a possible mobile-network uplink. An integrated reel is a packaging idea being explored to make cable storage and deployment part of the same portable system.

The vehicle would carry its own battery. The tether’s job is communication: control, video and telemetry. Early prototypes start with a practical wired setup, with lighter fibre options to explore later.

The starting point

Keep the dive close.

From a shore, pier or boat, the operator connects a controller and screen to the surface station. The tether carries video and movement commands to the drone. Local control is intended to remain useful without a cloud subscription or an internet connection.

Take a closer look

A headset could bring the underwater view into a personal virtual screen. A familiar controller gives the guest a way to explore.

Make it a shared discovery

An onboard TV keeps everyone part of the dive. Guests can spot marine life, suggest a direction and take turns piloting.

Offer another experience

Operators could add guided underwater sessions to an existing excursion. Pricing and profitability are questions for commercial pilots.

One setup.
Different audiences.

Local guests, remote pilots and viewers could make use of the same equipment at different times. Utilization has to be proven in real operations.

Add a dive to the boat trip.

A sightseeing cruise, fishing trip or private charter could offer underwater exploration as an additional activity. Guests watch on a shared screen, try the controller or join a guided headset experience. The commercial pilot would test demand alongside preparation time, battery changes, maintenance and staff attention.

Potential income: hosted experiences

A starting point at the water’s edge

From a pier.
From the shore.
From curiosity.

The concept also starts with a person, a controller and somewhere to launch.

Rocky coasts, lakes and marinas offer a different kind of exploration close to home. A portable setup could bring live underwater imagery to a nearby screen, without needing a boat.

Personal ownership is part of the idea from the beginning. Local piloting, recording and basic control are intended to stand on their own, with connected services adding options over time.

Proposed use cases depend on site suitability and operating conditions.

For private owners

Your boat.
Your next expedition.

There is another side to the cove you know. Remote Dive imagines a way to explore it from a small boat, a fishing skiff or a stationary personal watercraft.

Concept visualization

Start with your own discoveries.

Reach a suitable spot, stop and look beneath the surface. The proposed setup brings a drone, a surface hub and a familiar controller together, with the underwater view on a screen or in a headset. The appeal starts with a place you want to explore yourself.

Give a familiar trip another chapter.

For someone who already hosts fishing trips or coastal outings, a guided dive could become an extra experience for passengers. A private owner could also explore hosting remote guests, handling the launch and recovery while someone elsewhere takes a turn at the controls.

Proposed use cases. The illustrated watercraft is stopped; the headset shows the drone’s view. Equipment and operating procedures still need field trials.

Explore beyond your own shore

Night outside.
A world to explore.

Imagine a late night in Berlin while morning reaches the Thai coast. Settle into your chair, pick up a controller and join an underwater exploration on the other side of the world.

Berlin · Night at homeThailand · Morning at the reef

Our aim is a network of places worth exploring: tropical reefs, rocky coves, lakes and marinas. Choose a location for the next session, follow a host who knows it, then discover a different shore another day.

At the controls, your gamepad would move a real underwater vehicle. A local operator would prepare, launch and recover it, with priority to take over. Each session depends on a ready operator, a suitable connection and conditions at the site.

Concept visualization of a future network. Berlin and Thailand illustrate the idea; locations and sessions are not yet available.

Remote control. Local responsibility. Stabilization is designed to run onboard. The field operator retains priority.

Proposed session formats

Come to watch.
Stay to explore.

Public viewing creates a way in. Paid control reserves something physical: time with a real drone at a real place.

Follow an expedition.

Public viewing would let people discover a location and share the underwater view before deciding whether to participate. A broadcast can serve a wider audience while control remains with one authorized pilot.

Discover a placeJoin the viewGet readyTake a turnShare the discovery

The pilot’s video connection and the public broadcast are separate parts of the proposed system. No sessions are available to book yet.

The people behind a dive

Five roles.
One shared expedition.

One person can take several roles. Separating them creates room for local businesses, remote hosts and owners to participate in different ways.

01

Owner

Provides the hardware.

An owner could use the drone personally or place it with a local operator. Ownership need not require living near the deployment site.

02

Field Operator

Makes the dive possible.

Stores, charges, checks, launches and retrieves the equipment. This person monitors local conditions and retains priority control.

03

Mission Host

Brings people together.

Welcomes participants, guides the conversation and manages the pilot queue. A host could run a session from another location.

04

Remote Pilot

Takes a turn exploring.

Receives control for an authorized part of the session. The pilot chooses where to look and how to move within the mission’s limits.

05

Viewer

Shares the discovery.

Follows the underwater view and can become a participant. Watching, talking and requesting a turn are part of the social concept.

Hardware ownership, site operations, hosting and temporary control are distinct responsibilities.

The opportunity

Local people.
New places to dive.

Someone knows the cove. Someone has a boat. Someone else wants to see what is below. The proposed network connects these roles: independent local operators bring equipment and knowledge of a place; remote participants bring curiosity and demand.

Own the hardware

A repairable drone for personal exploration and commercial use. Hardware and accessories form the starting business model.

Hardware & accessories

Host the experience

A small-boat owner, fishing guide or dive centre could host the next underwater outing. The local operator prepares the equipment, handles launch and recovery and stays responsible for conditions at the site.

Tourism & local operators

Pilot from anywhere

Paid time at the controls would give remote participants access to real places, with shared viewing and guided sessions.

Remote sessions

Build the network

Independent owners could add locations at their own pace. Public streams introduce each place, while bookings and paid sessions could support both the operators and the platform.

A future marketplace

A proposed business model. Customer demand and operating economics remain to be tested.

The business, in stages

Sell the device.
Grow the reasons to use it.

The business model develops with the installed base. Each additional service should answer a real need discovered in use.

Start with the product

Hardware that stands
on its own.

Drones, accessories, replacement parts and commercial kits are the initial revenue directions. Repairability matters to individual owners and to operators preparing equipment for another day on the water.

  • Base devices and commercial bundles
  • Batteries, lights and tether options
  • Replacement and service components
Build paid experiences

Local operations.
Remote demand.

Tourism experiences and paid piloting sessions could create income around each deployment. The proposed platform could earn transaction fees while owners, operators and hosts agree how to share the work and proceeds.

  • Hosted onboard experiences
  • Remote and private sessions
  • Booking and transaction services
Add services when useful

Tools for a
growing network.

Fleet management, archives, creator tools and optional cloud features become relevant when enough people are using the system. The design principle is that basic local ownership remains useful without a mandatory subscription.

  • Operator and fleet tools
  • Optional recording and cloud services
  • Creator and discovery features

Unit economics remain to be measured: demand, utilization, staff time, network costs, servicing and equipment life all matter.

An expedition with an audience

Your coastline.
Your live story.

A familiar cove could become the setting for a regular underwater show. One person pilots the drone; another tells the audience what is coming into view. A small motorboat becomes the base for the story.

Live streams on YouTube and short recordings of dives could bring an audience back to a particular place and host. Scheduled explorations, guest pilots and conversations with viewers give each outing a different story.

Viewer support, paid events and sponsorships could become another income stream. Audience interest, platform eligibility and production costs would need to be tested before treating it as a business.

A field trip
the class can help steer.

A teacher, a local operator and a room of curious students could share the same underwater view. Remote participation opens possibilities beyond tourism.

Education

A teacher could host a remote field trip while students observe and take turns exploring. Marine biology, ecology and robotics are natural subjects for early educational pilots.

Research & observation

Researchers could join a shared session, discuss features and add observations. With permission, future dives might contribute records of habitats, species or underwater litter.

Inspection & mapping

Marinas and boat owners could explore visual inspection use cases. Sonar, measurement and mapping are possible later modules, with their own hardware and validation needs.

Potential applications, not existing deployments or validated scientific and educational outcomes.

Built to be worked on

A device to explore.
A platform to develop.

Replaceable components and accessible prototyping could let the hardware improve through real use.

A proposed Community Edition would bring together printable parts, a bill of materials, firmware and assembly guidance. Makers could help investigate thruster geometry, materials, tether handling and control feel.

For operators, modularity is practical: inspect a component, replace what needs attention and prepare for the next deployment. Pressure-balanced electronics are an engineering approach to investigate, with compatibility and pressure testing still ahead.

Repairable modulesPrintable prototypesOptional future sensors

Community files, SDKs and guides are proposed deliverables, not released resources.

Trust starts with the design

Remote exploration.
Local responsibility.

A host manages the experience. A field operator stays responsible for what happens at the site.

Control is designed to pass through a clear handover. Onboard stabilization handles the fast corrections, while local priority and command timeouts address interruptions in the remote connection.

Recovery is a set of engineering questions to validate. No single mechanism removes the risk of loss or entanglement.

Buoyancy and controlled ascent

The vehicle is intended to be slightly positively buoyant. Prototype work would test how it behaves when propulsion stops, alongside locally controlled ascent. Conditions and entanglement can still prevent a return.

Independent recovery mechanisms

Releasable ballast is a proposed mechanical recovery layer. Later work includes emergency flotation and independent control or reserve energy, so recovery is not tied to one normal system.

A separate location marker

An emergency locator buoy is a different component from the normal communications hub. Its line would help locate a trapped device; it should not be assumed to lift the vehicle or guarantee retrieval.

Preparation for the next dive

Operators would inspect the tether, check equipment and service activated recovery components before reuse. Repeatability and maintenance burden belong in the validation programme.

Future research

The exploration
could keep going.

Between human sessions, an autonomous operator could continue a bounded mission: observe, revisit points of interest and create a public stream under local supervision.

A participant’s turn would pause autonomous activity. The mission would be reassessed before continuing.

Concept visualization · future autonomy research
01 / Observe

Find something worth seeing.

A future decision layer could choose where to look next, while local control handles movement within the mission’s limits.

02 / Frame

Give the moment room.

Camera direction could slow down around a subject, adjust lighting and avoid repeating the same view. Wildlife distance comes first.

03 / Learn

Use evidence from real dives.

Recorded observations and human interventions could inform later development. Research starts by watching before acting autonomously.

The next conversations

A clear idea.
Real questions
to answer.

There is a difference between a compelling vision and a proven business. The next work connects the two through hardware trials and focused pilot experiences.

Discuss a pilot or investment
Is Remote Dive already available?

The project is at concept and prototype-planning stage. The first milestone is useful shallow-water piloting and video, followed by repeated operation and carefully scoped commercial pilots. The images on this page are design studies.

Is this a video experience or real control?

Real piloting is central to the proposal. A remote participant would command direction and movement; onboard software would stabilize the vehicle. Viewers could watch the same exploration without having control.

Would the system work without the internet?

Local control at a shore, pier or boat is a core design goal. Internet connectivity would add remote participation and public streaming. A boat-side satellite uplink is a possible future option, not validated Remote Dive compatibility.

What would the first VR experience look like?

The starting concept is an underwater live view on a virtual screen inside a headset, with a game controller for piloting. Head-linked camera movement and stereo imagery are separate future experiments.

How could an operator earn from it?

Proposed routes include hosted boat experiences, paid remote turns, private sessions and creator events. Revenue would depend on customer demand, operating conditions, staff time and equipment costs; no return is guaranteed.

What needs to be proven next?

Natural controls, useful footage, tether handling, repeatable recovery and equipment durability. Tourism pilots would then test the guest experience and workload. Remote sessions add connection quality, handovers and willingness to pay.
