The Dutch Suit That Digitizes Human Work for Robots | Dennis Kloppenburg - Xsens

Xsens has been building motion sensors for 26 years, and by Dennis Kloppenburg's account the largest corporations now put people in motion capture suits, force gloves and cameras for whole shifts of ordinary work and record everything they can to train robots. He tells factory owners to think hard before anyone films their floor, because the way they make things is the data their competitors would most like to have. The first time he walked into a robot factory in China, he watched humanoids climb stairs and cross rubble at a scale he had never seen. On 6 May 2025, the US investor Francisco Partners took full ownership of Movella, the parent of Xsens, in a debt-for-equity swap. On 25 August, Business Insider reported that Tesla had dropped motion capture suits and VR headsets for its Optimus humanoid and would train it mainly on video of workers. On 12 November, Xsens launched a new Xsens Link suit with Xsens Humanoid software for robot teleoperation and AI training, built to plug into ROS 2, NVIDIA Isaac Sim and MuJoCo. On 11 June 2026, Al Jazeera photographed workers in Tamil Nadu, India, who earn about €2.30 an hour filming everyday tasks with head-mounted cameras to train robots. This conversation explains why the companies teaching humanoids to work still put suits on people, and why the data those suits record is worth guarding. In this interview from The Robot Bureau, Rogier and Lei sit down with Dennis Kloppenburg, Innovation, Growth & Business Manager at Xsens, at the Humanoid Robots Summit Europe in Stuttgart in September. Each Xsens suit carries inertial measurement units, small modules with an accelerometer, a gyroscope and a magnetometer, and the company's sensor fusion and biomechanical models turn their readings into a moving human body, with magnetic immunity for factory floors full of metal. A camera loses track when the light changes or a box blocks its view, and it misses the elbow and shoulder rotation a worker uses to set a part down without scratching it, so Dennis sees the suit as the ground truth that tells a video model which of its footage is right. The first buyers were humanoid makers who needed a way to steer their robots, data farms came next, and he expects integrators working for logistics companies and manufacturers to follow, because the last five percent of each task has to be recorded on site. Chinese factories can mass-produce good electronics cheaply, he says, so Xsens puts its money into the algorithms and licenses its MVN software, which game developers already use to stream a suit straight into Unreal Engine. "We need to digitize ourselves into the computer." Xsens was founded in 2000 by two University of Twente graduates, and Dennis counts three or four Dutch companies at the front of physical AI data collection, most of them university spin-offs whose technology people around the world use without knowing where it comes from. Most of the investment still goes to the US and China, by his account, while Europe gives Xsens a large customer base, and the company is Dutch at its core with an American owner. His advice to European manufacturers, many of them short of people for the night shift, is to keep control of their recordings and think about vendor lock-in before an American or Chinese company films how they work. Rogier and Lei cover: whether cheaper synthetic data can stand in for motion capture, when gloves and a head camera are enough and when a worker needs the full suit, how Xsens keeps up with demand while component prices rise, whether Xsens is turning into a data company, and the suits worn by Lionel Messi and the kickboxer Rico Verhoeven that Xsens still keeps in its office.
