Engineers from Beijing have developed the world’s first robotic support system for underwater professionals. The new device, designed to be attached to the legs, greatly simplifies complex underwater tasks and reduces muscle strain.
The exoskeleton is equipped with a cable-driven actuator that operates at the knee. This design makes the device lightweight yet resistant to external factors. Built-in sensors continuously monitor movement parameters: bending angle, speed, and force. The control module analyzes this data and selects the optimal moment to activate support, providing assistance precisely when needed and synchronizing with the user’s movements.
The main advantage of the system is its ability to adapt to individual swimming styles. The exoskeleton does not impose fixed algorithms but adjusts to each diver’s technique, maintaining natural movement and full control. This is especially important for maneuvering in confined spaces or when working with equipment.
During tests involving six experienced divers, the device demonstrated high efficiency. Using the exoskeleton reduced air consumption by 22.7%, significantly extending underwater stay. Additionally, the physical load on primary leg muscle groups decreased by about 20%.
Test participants quickly adapted to mechanical assistance and did not experience discomfort. Their movements remained natural, and overall energy efficiency increased significantly. This opens up new possibilities for using the technology in marine research, construction, and professional diver training.
The development by Chinese specialists could be an important step forward in underwater robotics. The exoskeleton can make work easier not just for professionals, but also for enthusiasts, making dives safer and less exhausting.
