Oxybot is an advanced, autonomous lake protection system that targets the root causes of harmful algae, swimmer’s itch, and bacterial contamination before they threaten water quality. Each Oxybot buoy navigates designated areas using smart GPS guidance, continuously monitoring for early signs of contamination. Once identified, Oxybot deploys an innovative treatment process—combining hydraulic cavitation and plasma oxidation—to rupture and neutralize harmful algae and dangerous microorganisms, all without chemicals or environmental harm. By acting proactively and leveraging real-time data with closed-loop AI optimization, Oxybot delivers ongoing, safe, and effective water remediation, setting a new global standard for lake health.

Building on its powerful biological controls, Oxybot incorporates a state-of-the-art iron electrocoagulation cell to complete the water restoration cycle. After the initial destruction of algae and pathogens, water passes through this cell, where a low-voltage current across iron electrodes releases ferrous ions that rapidly bind with dissolved phosphorus. The resulting iron-phosphate compounds are insoluble, settling safely to the lakebed, and mirroring natural sedimentation found in healthy aquatic ecosystems. This crucial, chemical-free step removes the nutrients that enable algae to rebound, ensuring lasting water clarity and reducing the root cause of future blooms. The Oxybot system, through its integrated nutrient removal, not only remediates immediate threats but also actively restores natural balance—delivering a comprehensive, environmentally sound solution that outperforms conventional, reactive lake management approaches.

Oxybot leverages award-winning  instrument sensors to deliver precise, real-time readings of lake conditions. These advanced instruments continuously measure key water quality parameters—such as bacteria, algae, toxins and nutrient levels—and instantly transmit results to your smartphone via Lake Link, empowering users with up-to-date information wherever they are. By detecting changes and pinpointing elevated threats, the Oxybot’s AI-driven system swiftly analyzes this data and autonomously determines where and when proactive treatment is needed. This integrated approach ensures your lake remains safe, clear, and healthy.

By deploying Oxybot early in the spring, our advanced multi sensor system continually monitors water conditions—delivering real-time alerts if harmful algae, bacteria or excess nutrients are detected. This proactive approach means you’re notified of potential threats long before they become a problem, allowing for swift, targeted action.

Our process is completely safe for people, pets, and fish. You can swim, boat, or let your pets enjoy the water with total peace of mind. Oxybot eliminates harmful algae at its earliest stage—without resorting to chemicals—so your lake remains naturally healthy, inviting, and worry-free all season long.

Protecting Your Lake: Coverage Per Oxybot & The Power of Swarms

Each Oxybot is engineered to treat up to 1–2 acres (4,000–8,000m²) of lake surface every 24 hours under typical conditions, dispersing and circulating water with its high-performance 9GPM pump. This means an Oxybot continuously moves throughout its assigned zone, maximizing algae and bacteria neutralization and nutrient removal both at the surface and in the critical shallow areas where threats emerge.

For large lakes and distributed shorelines, deploying a coordinated swarm of Oxybots unlocks scalable, comprehensive protection. Multiple units work together autonomously—expanding coverage, increasing treatment capacity, and ensuring every sector receives proactive intervention. Swarms efficiently disrupt bloom formation across extended lakefronts, resorts, and communities, safeguarding water for recreation, wildlife, and property value.

At Ion Works, we are advancing lake science with two additional new autonomous models—Lakescape and OxyTrak—both designed to make high-quality lake surveying easy, reliable, and accessible to all.

Lakescape: Automated Depth Mapping

Lakescape automates the process of mapping lake bottom profiles through a sophisticated, grid-based navigation algorithm. Unlike traditional survey methods that rely on crewed boats and are rarely updated, Lakescape robotics consistently and efficiently charts even small, shallow, or hard-to-reach lakes. This provides up-to-date and highly detailed bathymetric data, empowering communities to manage their lakes with confidence.

OxyTrak: Dissolved Oxygen Profiling

OxyTrak is optimized for measuring dissolved oxygen (DO) throughout the entire water column—a key indicator of lake health and aquatic life sustainability. While most current methods offer only occasional spot-checks or require cumbersome manual deployment, OxyTrak’s autonomous path planning systematically collects high-resolution DO data across the entire lake. The result is clear, spatially complete DO profiles that are available  for managers and stewardship groups to act upon.

Dedicated to Innovation and Accessible Science

Ion Works’ lake robotics solutions set a new standard for accurate, automated, and user-friendly lake environmental monitoring. All data collected by Lakescape and OxyTrak is securely stored and accessible via our Lake Link cloud databank, offering lake managers, researchers, and communities an always-on, centralized hub for actionable lake intelligence.

In summary: Lakescape and OxyTrak expand the Oxybot family’s proven capabilities into professional-grade depth mapping and DO profiling. Our mission is to make advanced lake science available for every lake—delivering real-time insights, better decisions, and healthier water for all.

Oxybot combines immediate biological control with proactive nutrient removal to deliver a comprehensive, multi-season solution for harmful algal blooms.

Why Repeated Oxybot Deployments Are Needed

Will Oxybot eliminate all algae blooms in the first year? The answer lies in both the biology of harmful algae and the nutrients that fuel them. Oxybot is engineered to disrupt algae at their most vulnerable lifecycle stage—specifically by targeting and neutralizing buoyant vesicles and dormant cells (akinetes) resting in lake sediments. Many harmful species produce these akinetes, which can survive in sediments for years before rising to the surface when spring sunlight and warmer temperatures trigger their growth.

Because dormant akinetes build up over successive seasons, it’s possible for some to survive the first year, leading to surface blooms even with active Oxybot treatment. Repeated spring and summer deployments are essential: each year, newly activated akinetes and vesicles are intercepted and neutralized, gradually depleting the lake’s harmful algae “seed bank.” Over multiple cycles, the frequency and severity of blooms drop dramatically, as the population of viable akinetes is steadily reduced. This lifecycle-based remediation is strongly supported in the scientific literature and is critical for breaking the annual bloom cycle and restoring long-term lake health.

Nutrient Removal: Eliminating the Fuel for Regrowth

Oxybot’s unique advantage goes even further by removing the very nutrients—primarily phosphorus—that allow algae to rebound after initial control. Each buoy features an integrated iron electrocoagulation module that, after plasma and cavitation treatment, binds dissolved phosphorus from the water, sequestering it as stable, non-toxic iron phosphate on the lakebed. This dual-action approach not only attacks the algae directly but also strips out their future fuel supply, greatly reducing the risk of regrowth and making each subsequent year’s treatment even more effective.

By combining ongoing, targeted biological control with proactive nutrient removal, Oxybot transforms how lake management is achieved—delivering proven, science-backed protection for lake ecosystems and communities alike.

Yes, Oxybot can remove nutrients like phosphorus in addition to neutralizing algae and pathogens. Its integrated iron electrocoagulation cell is specifically engineered to bind and sequester dissolved phosphorus, helping to restore and stabilize lake ecosystems.

How the Iron Cell Works

After Oxybot’s cavitation and plasma processes destroy harmful algae and microorganisms, water is directed through the iron electrocoagulation (EC) cell. Inside, a gentle electric current flows through iron electrodes, releasing ferrous ions (Fe²⁺) into the water. These ions act as natural “coagulants,” rapidly binding with free phosphate to form insoluble iron-phosphate compounds, which settle harmlessly in the sediment. This step effectively strips out bioavailable phosphorus, removing the nutrient fuel that algae need to rebound.

Is Iron Electrocoagulation Safe for Lakes?

Iron EC is widely recognized as an environmentally sound technique. The iron-phosphate precipitate formed by this process mimics naturally occurring minerals found in healthy lakes and is non-toxic to aquatic life. Unlike chemical treatments, iron EC adds no foreign or persistent pollutants, and the reaction products are stable and inert under natural lake conditions. Routine maintenance ensures the system remains efficient and does not degrade lake quality.

Oxybot’s Role in Systemic Lake Recovery

Oxybot bridges the critical period of active bloom and pathogen suppression, while internal phosphorus recycling is broken and external inputs are reduced. Scientific consensus confirms that controlling internal cycling (such as by EC) and addressing upstream watershed sources together enable long-term lake health recovery. With both cycles under control, rooted plants and beneficial algae re-establish, helping to bind nutrients and further outcompete nuisance species—stabilizing the ecosystem for sustainable improvement.

Yes, Oxybot exclusively integrates a unique iron-based electrocoagulation cell, (Patent US 6358398 B1) enabling it to actively remove excess phosphorus from the lake water by chemically binding it as part of a stable mineral. In this process, Oxybot first destroys problematic algae and pathogens, then introduces Fe²⁺ ions from iron electrodes, which rapidly react with lake water dissolved phosphate ions (PO₄³⁻) to form insoluble iron (II) phosphate, following the reaction:

This compound, when hydrated in natural sediments, becomes vivianite with the formula:

Vivianite is a naturally occurring, highly stable mineral found in healthy lakebeds, recognized for locking away phosphorus long-term and preventing its re-release into the water, thus suppressing future algal blooms. Unlike harsh chemical treatments, iron is non-toxic when properly dosed and restorative for ecosystems—its use for phosphorus removal is widely documented and supported in scientific lake management literature. This dual-action system immediately improves water clarity and supports a balanced, self-sustaining lake environment.
