Petra emerges from stealth with $30M raised for tunnel-boring robot, Swifty – TechCrunch

Petra emerged from stealth this week and announced a $ 30 million Series A. The DCVC-led round will include additional ACME Capital Congruent Ventures, 8VC, Real Ventures, Elementum Ventures and Mac Venture, with up to $ 33 million in robotics funding. capital.

“We have invented a whole new way to excavate rocks, which will have a huge impact on the future of tunneling,” co-founder and CEO Kim Abrams said in a news-related release. rice field. “By providing a boring solution that puts utilities underground at an affordable price through high-grade rocks, it ultimately protects the community from wildfire exposure and disaster-prone areas, especially the Sierra Nevada Mountains. , Secure critical infrastructure such as the Rocky Mountains. And coastal areas. “

The news arrives when the company announces its success as a pilot for the robot Swifty. According to the company, the robot successfully bored a 20-foot tunnel through Sukquarzite at a speed of 1 inch per minute. Metamorphic rocks are famous for their hardness and are popular in the buildings in the upper Midwest where they can be seen. However, its strengths can also be a daunting task from infrastructure and other projects that require tunneling.

“Until now, there was no way to tunnel this kind of hard rock. Petra’s work is due to Swifty’s thermal drilling method, which efficiently penetrates rock without touching it,” said the company’s CTO. Ian Wright, co-founder of Tesla, who signed it, said. “Taking 20 feet of Sioux Quartzite, which is impossible hard, demonstrates its unique ability to affordably fill practically sized tunnels in high-grade hard rock.”

Robotic systems utilize machine vision, microtunneling through difficult materials using thermal drilling, rather than direct contact with rock. The company said in its release: “Switfy offers many new advantages over traditional micro-tunneling methods. Traditional micro-tunneling machines are designed for a single diameter, although Swifty has a diameter of 20-60 inches. It is the first robot to be able to boring a range and significantly reduces the cost of tunneling. “

The company cites a wide range of potential uses for such boring technologies, such as tunnel construction, maintenance and construction.
