All3 - Mantis
Mantis by All3 is the first autonomous construction robot built for real-world building sites, combining AI precision, modular tools, and heavy-duty performance to automate assembly, fastening, and finishing tasks.
About All3 - Mantis
All3 is rethinking construction with AI and robotics. At the center of its system is Mantis, the first purpose-built autonomous robot for on-site construction. Unlike general-purpose bots, Mantis is designed to work seamlessly with All3’s AI-powered architecture and prefabrication system, handling placement, fastening, finishing, and inspection with accuracy and speed.
Equipped with a telescopic reach of over 4m and a 100kg+ payload capacity, Mantis adapts to diverse structural and interior tasks using an interchangeable tool system. Compact enough to pass through a standard doorway, it is engineered for urban construction environments where space is tight and precision is critical.
Mantis completes All3’s vertically integrated workflow: AI agents optimise designs and compliance, modular robotic cells fabricate custom components, and Mantis handles on-site assembly. This removes the bottlenecks of traditional construction, enabling high-quality, bespoke buildings to be delivered at the cost and speed of mass production.
