Evidence & checks
Safety & supervisionCompany-published
Below that line, a deterministic loop running 1,000 times a second governs force, damping and emergency stops.Reviewed 2026-11-04View source
All3 Mantis is built to a safety standard ahead of the EU Machinery Regulation, which applies from 20-01-2027.Reviewed 2026-11-04View source

Before relying on it
Request the application-specific risk assessment and safety documentation; test emergency stops, exclusion zones and human supervision on site.

Field deploymentsCompany-published
Fully electric and modular, Mantis operates autonomously on urban construction sites, removing reliance on scarce skilled manual labour.Reviewed 2026-11-04View source
### Built for Real Construction SitesReviewed 2026-11-04View source

Before relying on it
Speak with a named contractor using this model on a comparable site; confirm scope, duration and operating conditions.

All3 unveils next generation All3 Mantis - the heavy-duty quadrupedal robot setting new benchmarks for construction automationReviewed 2026-11-04View source
## All3 unveils next generation All3 Mantis - the heavy-duty quadrupedal robot setting new benchmarks for construction automationReviewed 2026-11-04View source
The updated All3 Mantis sets new benchmarks for autonomous robotics: it is designed to carry payloads of up to 100kg while walking; it climbs stairs with its 45kg working arm attached; it locates and drives structural screws into building components with no operator in the loop.Reviewed 2026-11-04View source
That model drives fabrication: robotic production in an All3 factory turns each building's unique design into custom timber components, made without the usual custom-build premium and to the precision the assembly stage requires.Reviewed 2026-11-04View source

Before relying on it
Run a supervised site pilot against your crew baseline; count setup, rework, downtime and intervention, not just peak speed.

Operating limitsMixed claims — review
- One platform, interchangeable payloads and tools: Two mechanical interfaces carry power, data and safety signals to payload modules and tools.Reviewed 2026-11-04View source

Before relying on it
Validate terrain, weather, payload, power and runtime limits against the actual site.

Maintenance & supportCompany-published
Mantis training in the All3 labReviewed 2026-11-04View source

Before relying on it
Confirm local service coverage, replacement parts, operator training, response times and warranty exclusions.

Workflow integrationCompany-published
Integrated plug-and-play interfaces and MEP allow rapid and precise installation by Mantis.Reviewed 2026-11-04View source

Before relying on it
Test your actual plans, coordinate systems, data export and handoff to existing site workflows.

What we know

Four-legged robot with swappable modules handles structural assembly, fastening, and finishing with 100kg+ payload capacity.

Worth asking

How effective is the Mantis modular system when transitioning between significantly different construction tasks on the same site?
