Fri, 06 Feb 2026 Can robots ever be graceful?

Firms are working to make the motors that drive robots more efficient and cheaper.
To create a functional and precise giant walking robot, British YouTuber James Bruton developed an intricate system of motors and gears that can control movement with precision. This effort sparked the idea for more sophisticated actuators that could mimic human-like movements without being cumbersome or inefficient. Currently, robots lack sufficient actuators to enable them to move with agility and intelligence. Leading robotics companies, such as Boston Dynamics and Humanoid Robotics, are in need of better actuators. These components allow for efficient movement and would be crucial in enabling humanoid robots to interact safely with humans. According to experts, the existing DC motors used in most robots today have their limitations when it comes to torque and power. A new generation of actuators is being developed that incorporates advanced technologies like back-driveability, high precision, and energy efficiency. Firms like Schaeffler are working on developing highly controlled movement capabilities for humanoid robots using sensors and real-time data feedback. Researchers are also exploring alternative approaches such as soft robotics powered by air, which can walk on land and in water without being damaged by liquids. Another idea is actuators made of elastomers – flexible materials like rubber that contract or expand when voltage is applied. The ultimate goal for many experts is to create robots that move with the same level of agility and efficiency as humans. This would require not only advances in actuator technology but also advancements in artificial intelligence, so that robots can interact safely and effectively with their environment.
