Petra emerged from stealth this week, asserting a $30 million Sequence A. The spherical, led by DCVC, brings the robotics firm’s funding as much as $33 million, with extra participation from ACME Capital Congruent Ventures, 8VC, Actual Ventures, Elementum Ventures and Mac Enterprise Capital.
“We’ve invented a totally new solution to excavate rock and this may have profound implications on the way forward for tunneling,” co-founder and CEO Kim Abrams mentioned in launch tied to the information. “By delivering a boring answer that affordably undergrounds utilities by way of high-grade rock, we will lastly defend communities from publicity to wildfires and make sure the security of important infrastructure in disaster-prone areas, particularly in locations just like the Sierra Nevada mountains, Rocky Mountains, and coastal areas.”
The information arrives as the corporate is asserting a profitable pilot of its robotic, Swifty. In response to the agency, the robotic efficiently bored a 20-foot tunnel by way of Sioux Quartzite at a charge of 1 inch-per-minute. The metamorphic rock is notoriously exhausting, making it a preferred alternative for buildings within the higher Midwest area through which it’s discovered. That power, nonetheless, additionally makes it a formidable problem from infrastructure and different tasks that require tunneling.
“No tunneling technique has been capable of tunnel by way of this type of exhausting rock till now. Petra’s achievement is because of Swifty’s thermal drilling technique, which effectively bores by way of rock with out touching it,” mentioned Tesla co-founder, Ian Wright, who has signed on as the corporate’s CTO. “Boring 20 ft by way of impossibly exhausting Sioux Quartzite proves our distinctive functionality to affordably bury utility sized tunnels by way of high-grade exhausting rock.”
The robotic system makes use of machine imaginative and prescient, microtunneling by way of troublesome supplies with using thermal drilling, quite than making direct contact with the rock. The corporate notes in a launch, “Switfy offers quite a few novel benefits over standard microtunneling strategies. Standard microtunneling machines are purpose-built for a single diameter. Nonetheless, Swifty is the primary robotic able to boring a variety of diameters between 20-60 inches, dramatically lowering the price of tunneling.”
The corporate cites a variety of potential makes use of for such boring applied sciences, together with building, upkeep and the creation of tunnels.
