Start-up Built raises $15m to develop robo-bulldozer tech
Built Robotics, an autonomous-machinery start-up founded by ex-Google employee Noah Ready-Campbell, has raised $15m in an NEA-led funding round. The proceeds will be used to hire engineers to help bring Built's robo-bulldozer technology to market. The 10-person team can retrofit heavy machinery to use the technology.

Noah Ready-Campbell's first job out of college was at Google . It was 2010, the year the company touted its plan -- or then, what seemed like a far-fetched dream -- to build self-driving cars. "They announced it and everyone looked at each other and we were like, why are we even talking about this," Ready-Campbell, who's now 29, told CNBC. "There's no way it's going to work." Seven years later, the technology is working. In fact, it's so far along that in California more than 40 companies have licenses to test autonomous vehicles, with the trucking industry not far behind. Ready-Campbell, whose dad was a general contractor, is getting in on the action and taking advantage of the dramatic advances in automation to go after construction. For the past two years, he's been developing software and sensors that can turn off-the-shelf excavators into robots that can dig holes with precision for hours without a break. From a small dirt field in a sparsely populated part of San Francisco, Ready-Campbell's 10-person start-up, Built Robotics, has been stealthily operating a retrofitted skid steer, directing it via a computer program to move around dirt.

The software allows a contractor to geofence the project so the machine can't go rogue. Then you program in the exact parameters and where to move the dirt. If Built Robotics is a success, some job displacement is inevitable. But Ready-Campbell said there's currently not enough skilled labor to fulfill all the demand for new roads, dams and bridges, and much of the work is dangerous or tedious. "I've talked to some operators and they've said there are parts of my job that are really dangerous and there parts of my job that are really boring," Ready-Campbell said. "If you can have a robot do those things and I can focus on the parts that really take human judgment, then that's good for me."

Ready-Campbell said it's too soon to say how the technology will be priced. He's optimistic that there are multiple ways to make money, whether it's selling the sensor kits to companies like Caterpillar and John Deere for their machines, selling to contractors for retrofits or renting out the technology for projects. Carl Bass, the former CEO of Autodesk and a roboticist in his spare time, first checked out the Built Robotics technology about nine months ago, when he visited the start-up's headquarters. It's not much of an office. Rather, it's a white tent with a few work stations, a weight-lifting area, a couple couches and a coffee maker. "As somebody who's seen a lot of start-ups, this one may take the cake as far as the proverbial garage," said Bass, who's now a Built Robotics investor and board member.
