Ultrafast lasers could give robots a new category of precision manufacturing work

[Grace9]

Industrial robotics is drawing record investment, with robotics funding reaching 47.4 billion dollars in the first half of 2026 alone, an 80 percent jump over the same period the previous year according to Crunchbase. Yet most industrial robots still perform relatively basic mechanical tasks, gripping, screwdriving, bolting, drilling and packing, according to Nikolajus Gavrilinas, co-founder and CEO of Lithuanian laser manufacturer LITILIT, who argues the next opportunity lies in equipping robots with tools capable of genuine precision manufacturing rather than simple mechanical handling

The specific technology LITILIT is betting on is the femtosecond laser, which fires pulses lasting only a few quadrillionths of a second, transferring energy so quickly that surrounding material experiences minimal heat damage, an effect often called cold laser processing. That precision already makes femtosecond lasers valuable in semiconductor manufacturing, medical device production and microelectronics, with potential robotic applications including drilling through-glass vias for semiconductor interposers and cutting complex curved glass components for foldable devices, tasks demanding both exceptional accuracy and minimal thermal distortion

The practical barrier has been size, most femtosecond lasers originated in research environments where bulk and maintenance complexity mattered less, making them impractical to mount directly on robotic arms. LITILIT says its systems run 1.5 to 2 times smaller than conventional platforms, and the company plans to begin production at a new Vilnius facility in October 2026, targeting up to 3,000 units annually. Curious what people think about this specific bet, does shrinking a research-grade laser down for robotic integration genuinely unlock a new manufacturing category, or does cost and reliability at industrial scale remain the harder unsolved problem
