ANTHBOT HoloSense Quad-Fusion Navigation System Explained

The ANTHBOT HoloSense is a quadruple fusion navigation system for robot lawn mowers —initially featured in M5 Pro/M9 Pro. It combines 360° LiDAR, RTK/NetRTK and AI Vision in a single, unified system to achieve centimeter-level positioning accuracy in any scenario while eliminating the need for boundary wires.

HoloSense Fusion System Suitable for All Lawns

To ditch 'dumb' boundary wires, the latest robot mowers are leaning on a high-tech arsenal of RTK, LiDAR, and AI vision. On paper, this is great news—tech for every lawn! But for most people, it’s just a dazzling puzzle.
At the end of the day, you don’t want a PhD in navigation; you just want a mower that works. That’s where the ANTHBOT M5 Pro and M9 Pro step in. Powered by the HoloSense fusion system, these mowers handle all navigation scenarios from wide-open turf to deep tree shade and tricky corners. Now, users can choose a robot lawn mower without digging into navigation terms.

Advantages of HoloSense Fusion Navigation System

At the heart of the M5 Pro/M9 Pro lies HoloSense Fusion—a seamless blend of 360° LiDAR, RTK/NetRTK, and AI Vision. This trio works in perfect harmony to give your mower the "autopilot" soul, ensuring every blade of grass is handled properly.

360°LiDAR, Free Move in Fenced, Complex Lawns

LiDAR (Light Detection and Ranging) is a ranging technology that bounces laser beams off the surrounding objects to calculate the exact distance and create highly accurate 3D maps. LiDAR works best when there are featured shapes instead of flat planes in the surroundings. The calculation method is surprisingly simple with the formula d = (c × Δt) / 2, where c represents the speed of light, and Δt indicates the time of flight. Its rationale is depicted by the following diagram.

LiDAR navigation gives M5 Pro/M9 Pro unique advantages. It masters fenced and complex garden landscapes such as wall corners, tree shades, and narrow footpaths between yards. LiDAR also works independently of ambient lighting conditions, so it allows robot lawn mowers to move freely at night or in dark conditions. And in an extreme case, it has no issue finding its way to the charging base installed indoors.
Even better, the LiDAR in the HoloSense system is spinning 360° to constantly scan and update the map, ensuring a flawless cut every single time.

RTK/NetRTK, Accurate GPS Positioning in Open Areas

RTK (Real-Time Kinematic) uses GPS satellite signals for absolute positioning in open environments. Hard to understand? Just take it as the navigation feature of your smartphone with an enhanced GPS receiver. It fixes LiDAR’s weakness: getting "lost" on flat, uniform grass that looks the same in every direction. RTK technology is the gold standard of navigation for open flat lawns, and it works regardless of the lawn size. 
Picture this: your mower is cruising along the lawn edge where the lush grass meets a concrete driveway. To a LiDAR sensor, that flat, grey-on-green horizon can look like a blur, causing the mower to drift or 'wander.' This is where the RTK excels. It locks onto GPS satellites to guide the mower in a perfectly straight, surgical line. It is also worth noting that M5 Pro/M9 Pro adopts the full-band RTK that can receive all bands of GPS satellite signals, so its signal strength is 50% higher than that of the competitors.
Plus, the HoloSense fusion system offers the 4G-enabled NetRTK. It delivers the same centimeter-level accuracy without the hassle of installing a physical base station.

AI Vision, Seeing Low-Lying Objects and Color Changes

AI Vision has been widely used for face recognition and product defect detection. After simple transplanting, it proves to be the most reliable and affordable way for robot lawn mowers to avoid obstacles. AI Vision doesn't just "see" shapes; it understands color and texture. In fact, AI Vision is the most effective way to recognize spot tricky, low-profile hazards like picnic blankets, garden hoses, or even dog waste.

LiDAR vs RTK/NetRTK vs AI Vision

Apparently, each of the three navigation technologies has its strengths and weaknesses. Here is a quick overview of them in a comparison table.

Fusion Is More Than Adding Together

As said above, the HoloSense fusion system of M5 Pro and M9 Pro enjoys all the strengths of 360° LiDAR, RTK/NetRTK, and AI Vision. Not only that, it actually boosts the navigation performance in all aspects by fusing the strengths together.

 Here is an example. When the mower goes under a large stretch of tree canopies, the 360° LiDAR is in full play to scan the exact shapes in the surrounding for navigation, while the AI Vision is busy to tell apart lawn grass from the tree roots, and very likely the RTK signal is tracking the mower’s position with GPS, so it always knows the way home and won’t get stolen.

In addition, the HoloSense fusion system enables a true drop & mow experience. You can start mowing with no need to bury any wire or install any pole station. It represents the best technology and the easiest operation. 

With that being said, forget the navigation terms; just get an M5 Pro/M9 Pro robot lawn mower based on your lawn size. It can not go wrong! You can find more information about M5 Pro/M9 Pro on our official website at the link here.
