Gravis Robotics
Series A
Builds retrofit autonomy kits that turn existing excavators into robotic earthmoving systems.
The company's commercial offering is a retrofit autonomy stack: the Gravis Rack rooftop control kit plus the Slate tablet. The Rack adds cameras, LiDAR, GNSS, and edge compute to excavators and loaders from about 10 to more than 100 tons, including Caterpillar, Case, Develon, John Deere, JCB, Hitachi, Sumitomo, Yanmar, and Volvo machines.
Slate lets crews mix in-cab copilot guidance with tap-to-dig autonomy, field command, and remote fleet supervision. The same software handles truck loading, trenching, bulk earthwork, stockpile work, and live 3D surveying without forcing contractors onto a single OEM ecosystem.
Gravis trains soil-aware models on simulated earthmoving so the same software can adapt to machine size and brand rather than cloning one operator or locking customers to one OEM. The kit is designed for the messy, changing ground of live civil sites instead of static warehouse or highway settings, and it can raise throughput by up to 30 percent versus peak manual cycles.
Because the hardware retrofits machines already in dealer and rental fleets, contractors can add autonomy without replacing iron. Partnerships with Holcim, Taylor Woodrow, Flannery Plant Hire, Develon, and Hitachi give the company both field data and distribution through OEM and hire channels.
Gravis sells and rents a retrofit kit rather than new excavators. The official hardware page offers turnkey rental and purchase options through local dealers and plant-hire partners, including Flannery in the UK and OEM dealer networks such as Develon.
List prices are not published on the first-party site. The commercial motion is quote-led, with machines already equipped with the Gravis Rack offered as a combined rental package so contractors can trial autonomy on mixed fleets without a fleet replacement.
