Mantis

Model: mantis

Mantis is All3's four-legged autonomous construction robot for on-site assembly, designed for All3's vertically integrated building process rather than standalone consumer sales. Official materials describe a fully electric, modular platform with embodied AI trained on All3's building logic, reconfigurable tools, adaptive leg stance for doorways and tight zones, and swappable payload/tool modules for placing, fastening, finishing, drilling, and inspecting building elements. All3 lists 100 kg+ payload capacity, a 4 m telescopic reach, millimetre-level placement accuracy with plug-and-play connectors and positioners, and indoor/outdoor operation across uneven surfaces, stairs, and multi-storey interiors. May 2026 coverage of All3's $25 million seed round reported plans to deploy robot fleets on first commercial construction projects in Germany in 2026-2027; public sale pricing and many hardware specifications have not been disclosed.
