On Monday, August 17, construction autonomy had its loudest day yet. Gravis Robotics, an ETH Zurich spinout, raised a $200 million Series A led solely by SoftBank, the largest the sector has seen, at a $1 billion valuation. Hours later, San Francisco’s Bedrock Robotics said its retrofitted excavators were digging on live, paying US sites with nobody in the cab. Two different bets, one landing the money and one crossing the operator-out line, both riding on machines contractors already own.
Robotics announcements usually arrive one at a time, and most of them are demos. August 17 was different. Within the same day, the money side and the operational side of construction autonomy both moved, and they moved in different places.
In Zurich, Gravis Robotics landed the biggest funding round construction robotics has recorded. In Nevada and Texas, Bedrock Robotics said its excavators were doing real earthmoving on commercial jobs with an empty seat. One is a capital story with a European postcode, the other a milestone story with an American one. Together they say the race has stopped being about whether machines can run themselves and started being about who scales first.
The money moved to Zurich
SoftBank’s $200 million is the largest Series A construction robotics has seen
Gravis Robotics raised $200 million in a Series A with SoftBank as the sole investor, described by both as the largest round in construction robotics history. It puts the post-money valuation at $1 billion, making the Swiss firm Europe’s newest robotics unicorn. Founded in 2022 as an ETH Zurich spinout, Gravis does not build machines. It makes a bolt-on control unit, the Gravis Rack, plus an assistance layer called Gravis Copilot, that turn mixed fleets into semi-autonomous or autonomous ones.
The kit is hardware agnostic by design, fitting excavators and other heavy equipment from names including Caterpillar, John Deere, Volvo, Hitachi and JCB. Gravis says its systems are already deployed across four continents and can lift jobsite productivity by up to 30%, with partners and customers that include Holcim, Taylor Woodrow and HD Hyundai. This is a scaling round for hiring and global rollout, not a first proof of concept.
The location matters as much as the number. European robotics startups raised 2.67 billion euros in the first half of 2026, more than the previous two years combined, so Gravis is riding a real surge, not a one-off. The largest cheque in the category just went to a European deep-tech team, and a Japanese giant wrote it alone.
- No fleet replacement. The kit rides on machines you already own, so no capital order and no wait for new iron.
- Resale value stays intact. Retrofit kits install without permanent modification, so a machine can revert to manual or be sold on.
- Mixed fleets, one system. Hardware-agnostic kits work across manufacturers, which suits a real equipment yard.
The milestone landed in Nevada
Bedrock put excavators to work with nobody in the cab
The same day, Bedrock Robotics said excavators running its system were operating fully autonomously on live customer sites, with no operator on board. The named jobs are a water treatment facility in Nevada with Sundt Construction and a 1.2 million cubic yard civil sitework project with Zachry Construction, plus a multi-million cubic yard earthwork job with Champion Site Prep in Texas. These are scopes with owners, schedules and money attached, not a fenced-off test pad.
Bedrock is a San Francisco company founded in 2024 by former Waymo engineers, led by Boris Sofman, and has raised around $350 million to date, including a $270 million Series B in February 2026. Its Operator kit retrofits excavators from 20 to 80 tons in a day, fitting cameras, LiDAR, GPS and onboard compute above the cab. A site manager sets the plan, the machine handles perception, planning and digging, and stops on its own if a person or object gets too close.
Why this counts as a threshold: through 2025, autonomous earthmoving meant supervised autonomy, with a person still in the seat. As recently as February, Bedrock called operator-out deployment a target it was working toward. Removing the person is the moment the technology stops being an assistant and starts returning an operator to the labor pool.
The biggest challenge we face isn’t just finding operators; it’s keeping experienced ones engaged when we need them for months of repetitive earthmoving in remote locations.Dan Green, Project Manager, Sundt Construction

What it means if you run projects, not funding rounds
Both bets ride on the machines you already own
The retrofit model is the reason either story reaches your yard. A kit that installs in a day, works across manufacturers and comes off without permanent damage is a far easier decision than a fleet swap, and it protects resale value, the objection most fleet managers raise first.
Then there is the labor math, which is the WIIFM that lands hardest. The Associated Builders and Contractors estimates the US construction industry needs to attract about 349,000 net new workers in 2026 alone, and skilled operators are among the hardest roles to fill, especially on remote jobs with months of repetitive earthmoving. An operator-out machine covers hours a crew cannot staff at all, and frees experienced operators for the work where judgment matters. That is the framing the contractors use, and a more honest read than a jobs-versus-robots headline.
The caution is worth stating plainly. Contractors will judge operator-out autonomy on incident data gathered over months, not on a launch announcement. That a general contractor was comfortable running it on public water infrastructure, where nobody takes casual risks, tells you something, though not everything.
Two companies, two different bets
One is scaling capital, the other crossed the operator-out line
It is tempting to lump the two together, and the market does, but their week pointed in different directions. Gravis’s news was capital: the biggest round in the category, to roll a proven retrofit platform out faster. Bedrock’s was operational: the first claim of commercial earthmoving with an empty cab. Same idea, autonomy on existing iron, at two stages of proof.
For a contractor weighing a first move, the distinction is practical. If you want an operator-assisted system with heavy financial backing behind its rollout, one profile fits. If you are watching for the point where a machine runs a scope unattended, the other is the one to track. The table below lays them side by side.
| Gravis Robotics | Bedrock Robotics | |
|---|---|---|
| Origin | ETH Zurich spinout, 2022, based in Zurich | Waymo alumni, 2024, based in San Francisco |
| What they sell | Gravis Rack retrofit unit plus Copilot, hardware agnostic | Operator retrofit kit for 20 to 80 ton excavators |
| Latest funding | $200M Series A led by SoftBank, $1bn valuation | ~$350M raised to date, incl. $270M Series B |
| Autonomy stage this week | Scaling semi-autonomous and autonomous retrofits | Claims operator-out work on live commercial sites |
| Where it is running | Deployed across four continents | Nevada, Texas, on named contractor jobs |
Both landed on Monday, August 17, 2026. Gravis Robotics raised a $200 million Series A led solely by SoftBank, described as the largest round in construction robotics history, at a $1 billion valuation. The same day, Bedrock Robotics said excavators running its system were performing productive work on live commercial US sites with no operator in the cab. (Source)
Not in the same claim. Gravis retrofits mixed fleets for semi-autonomous and autonomous operation and says systems are deployed across four continents, but its August news was about capital and scale rather than a specific operator-out commercial milestone. Bedrock is the one claiming productive work with an empty cab this week. It is fair to describe them as two stages of the same idea, not identical products. (Source)
No. Both companies sell retrofit kits that mount onto excavators contractors already own. Bedrock installs in about a day with no permanent modification, so the machine keeps its resale value and can revert to manual work. Gravis takes the same hardware-agnostic approach across multiple manufacturers. That is the whole commercial pitch: autonomy without a fleet swap. (Source)
A supervised machine still consumes an operator who sits in the seat. An operator-out machine returns that person to the labor pool and can keep working through hours a crew cannot cover. That is the point where the math on a bulk earthworks program changes, which is why the industry treats the empty seat as the milestone that counts, above any sensor spec or funding figure. (Source)
The contractors using it frame it as capacity, not replacement. With the Associated Builders and Contractors estimating a need for around 349,000 net new US construction workers in 2026, autonomy is covering repetitive earthmoving hours that are hard to staff at all, freeing skilled operators for more demanding work. Sundt’s own team has described it as taking monotony off a crew’s list rather than going from people to no people. (Source)
The early wins are on large, repetitive, remote scopes, where the economics are clearest and skilled operators are hardest to keep. Bedrock’s kit fits excavators from 20 to 80 tons, which covers most of a heavy civil yard, and Gravis targets mixed fleets broadly. Smaller and more varied sites will follow as the systems prove out, but bulk earthmoving is where the value shows up first. (Source)
Incident and reliability data over months, on scopes like your own. The safety design leans on a 360 degree sensor picture and an automatic stop when a person or object gets too close, and the first live deployment sits on public water infrastructure, which is a cautious environment. That is encouraging, but the honest answer is that operator-out autonomy earns trust through logged performance, not launch day. (Source)
