Conventional transmission architectures are reaching their limits in the most demanding robotics applications. General Robotics develops compact, high-torque actuators for next-generation robots, powered by its patent-pending RingSun™ gear technology. Designed to combine high torque density, high transparency, excellent mechanical reversibility, and high efficiency at low speeds, these actuators meet the needs of humanoid robots, exoskeletons, and advanced robotics.
The startup’s ambition is to strengthen Europe’s technological sovereignty in robotics by building a competitive European actuator platform. General Robotics has filed two international patent applications under the Patent Cooperation Treaty (PCT) and is currently developing its first commercial actuator based on RingSun™ technology. By 2029, the goal is to reach mass production with an annual capacity of over 300,000 units while achieving profitability.
The business model is B2B hardware: General Robotics designs and supplies integrated actuators to robot manufacturers (OEMs) and system integrators. Revenue begins with prototype development, engineering support, and small batches, then scales through recurring actuator sales as clients move to mass production.
The next step
The RingSun™ concept has been validated with an initial all-metal prototype, and the second-generation gear prototype is now entering performance testing. Once validated, it will be integrated into the first commercial actuator. The startup expects to spend about six months reaching a commercial version suitable for an initial production run of 200 to 1,000 units, followed by a major industrialization phase throughout 2027 and part of 2028, paving the way for mass production starting in 2029.
Several milestones structure this sequence: validating the performance of the second-generation gear, integrating it into the first commercial actuator, securing initial client integrations, forming industrial partnerships, and preparing for a Seed funding round. In parallel, the team is building the industrial roadmap required to scale from a few hundred units to industrial-scale production.
