Path Robotics Inc., a company specializing in automating industrial welding processes, has secured $300 million in a Series E funding round. Georgian led the investment, with participation from a consortium that included the venture capital arms of Yamaha Motor Co. and Navier Corp., one of South Korea’s largest tech firms. The fresh capital injection brings Path Robotics' valuation to $2.45 billion.
Path Robotics has been at the forefront of addressing the challenges associated with automating welding tasks, which have historically been difficult due to heat-induced metal distortion. This phenomenon occurs when the heat from a welding torch causes metal parts to warp unpredictably. Such distortions can disrupt the operations of robotic arms that follow static, pre-programmed welding plans. Additionally, inconsistencies in mass-produced metal parts often necessitate adjustments in welding procedures, which traditional automation software struggles to accommodate.
The company's solution to these challenges is an AI model named Obsidian. This model is designed to power industrial robots equipped with welding torches, enabling them to adapt to the changing shapes of metal parts during the welding process. Obsidian can also automatically account for unexpected variations in parts, ensuring a more seamless welding operation.
Obsidian operates by using four lasers attached to the welding torch to illuminate the parts being joined. The reflected light is captured by a pair of cameras, allowing the system to monitor the welding workflow in real-time. This data collection occurs not only during the welding process but also before and after each run. The gathered data feeds into what Path Robotics calls a 'weld world model', which is used to generate simulated welding projects. These simulations are crucial for training Obsidian's AI capabilities.
Initially developed for large robotic workstations known as welding cells, Obsidian's application has expanded. In April, Path Robotics introduced Rove, a four-legged robot that utilizes Obsidian to automate shipbuilding tasks. The company asserts that its software can also be applied to the production of vehicle parts, power generators, utility poles, and other heavy equipment.
Path Robotics' CEO, Andy Lonsberry, highlighted the increasing demand from manufacturers for solutions that expand production capacity beyond what traditional automation can achieve. “This capital allows us to scale our welding business alongside our customers while investing further in the data, compute, and model development needed to take on every task before and after welding, ” Lonsberry stated.
