Gravis Robotics vs Pronto

• Machines: Gravis supports excavators and wheel loaders from 10 to 100-plus tons for construction, quarry and mining work and says the RACK has been installed on a dozen brands; it does not support trucks, dozers, forklifts or graders. Pronto automates haul trucks and says it is OEM, vehicle and application agnostic, including class 8 haulers and support vehicles.
• Retrofit requirements: Gravis needs machines that can be controlled electronically (electro-hydraulic pilot valves); machines with legacy mechanical pilot valves can take a retrofit EH valve from a local hydraulic shop or its partner network. Pronto fits a retrofit drive-by-wire kit and says implementation needs little if any infrastructure change, but wireless connectivity is required for every deployment; its Pollen Mobile subsidiary builds private LTE networks for mine sites.
• Sensors and compute: Gravis lists a forward camera and LiDAR, rear GNSS RTK masts with HDR cameras and 3D LiDAR, surround-view cameras and automotive-grade edge compute that keeps working offline. Pronto describes a camera- and GPS-based stack that it says is lighter and cheaper than radar- and lidar-based systems, with machine-learning object detection and redundant neural networks.
• Setting the work: Gravis jobs are defined on Slate from CAD/BIM geometry or reference points set by touch, bucket or XYZ values, run as in-cab copilot, field command or remote orchestration of one or more machines, with live cut/fill coloring, AR overlays of georeferenced models and dumping into a spoil pile, hopper or a detected truck. Pronto learns a haul route after an operator drives it once; operators dispatch trucks to saved routes from a smartphone app that also shows fleet location and per-truck fuel, payload and utilization, with programmable site rules of the road.
• Safety controls: Gravis's Slate tablet has an integrated wireless stop. Pronto puts all-stop buttons in manually operated equipment that works around its trucks and offers driver assistance, collision avoidance or L4 autonomy depending on site maturity.
• Together on one site: a Gravis excavator detects and loads dump trucks; Pronto runs the trucks. Neither vendor's pages describe an integration between the two.
• Company news (vendor statements): Gravis's Aug 17, 2026 post announces a $200M raise. Pronto's newsroom says Atoms acquired it on April 6, 2026, and lists a Hitachi Construction Machinery partnership (July 2026), Komatsu Smart Quarry Autonomous powered by Pronto (Aug 2025) and its July 2025 acquisition of SafeAI.
• AI tags: both stay AI-first (Gravis describes learning-based, soil-aware control and an AI perception stack; Pronto's autonomy runs on machine-learning detection).
• Pricing (checked Oct 20, 2026): neither publishes prices, and /pricing returns a not-found page on both sites. Gravis mentions turnkey rental and purchase of Gravis-equipped machines through local dealers and rental providers, with no figures; Pronto's calls to action are Contact us and a sales email address.
• Not used here: Gravis's up-to-30% throughput claim and "trusted by" line, Pronto's labor, fuel, insurance and tonnage claims and haul-truck deployment counts, and both vendors' customer quotes. Neither tool has been tested by Means & Methods Lab.
