The Anthbot R7 uses an extending trimmer to tackle edges

Effective edge trimming has long been the bane of a lawnbot-maker's life. After all, what good is a robot mower if you then have to go in with a side-trimmer to clean up all the lawn edges afterwards? Anthbot's newest robo-mower — the R7 Series, on show at IFA 2026 — has an innovative solution.
The brand has tacked a string trimmer onto the side of the lawnbot. Or, more accurately, onto a "robot arm", mounted to the side of the lawnbot. This arm is designed to adjust to follow winding lawn boundaries, ensuring "zero-gap edge cutting without manual touch-ups". Anthbot dubs the system 'EdgeEase'.
I saw it being demoed — albeit on an AstroTurf lawn, without any actual cutting. The arm movement is smooth and functions well, tucking neatly away when not required. (It's a little less visually impressive than Segway Navimow's own mechanical side-trimming system, but which system functions better remains to be seen.)
I've seen side-mounted blade trimmers before, but this string version feels like a slightly safer option to be protruding out into the open… at least when not in use. Of course, when spinning, those strings will be able to slice just as effectively as a blade.
On that point, I'm surprised Anthbot hasn't added any kind of protective casing. There is a camera specifically dedicated to keeping an eye on the trimming arm, but it's still putting a lot of trust in those obstacle-spotting skills.
The EdgeEase string trimmer is the headline addition, but I was also interested to see Anthbot has included an infrared sensor for animal detection. This is designed to pick up thermal signals from critters like hedgehogs that might be hidden in the grass, so the mower can avoid them.
These are two standout features in what looks like an altogether extremely capable lawnbot. For the main mowing, it uses two floating cutting discs, designed to adjust to uneven ground for a clean finish. There's also all-wheel drive — precisely powered by four drive motors and two independent steering motors. That's designed to help with traction and maneuverability.

The navigation suite includes LiDAR, RTK, and three AI-backed cameras (including that trimmer cam) to provide "robust, all-scenario positioning" that won't drop out if, for example, the satellite signal is blocked. Anthbot emphasizes the R7 Series is "designed to handle the complexity of real gardens rather than idealized, flat lawns".
The ANTHBOT R7 Series comprises two lawnbots: the R730 and R720. The R730 is designed for lawns up to 3,000㎡ and has the string trimmer included as standard. The R720 has a smaller battery and is meant for yards up to 2,000㎡, and the string trimmer is an optional extra.
