# Pave Robotics > Robots that repair roads. Semi-autonomous asphalt crack-sealing platform for DOTs, municipalities, and paving contractors. Backed by Y Combinator (W25). Pave Robotics builds the Tracer-125, a truck-towed robotic platform that detects and seals cracks in asphalt roads with a purpose-built robotic arm and heated rubberized sealant. One operator runs the system for up to 16-hour shifts, keeping crews out of harm's way during lane closures. ## Pages - [Home](/): Product overview, technology, field operations, specs, company, and demo request.
