In a groundbreaking study published in ‘IEEE Access’, researchers have developed an innovative bidirectional control interface designed for the teleoperation of hyper-redundant robots, particularly in the challenging environments of nuclear fusion reactors. Led by Ludovica Capodivento from the Unit of Advanced Robotics and Human-Centred Technologies at the Università Campus Bio-Medico di Roma, this research addresses the pressing need for enhanced safety and efficiency in remote handling tasks.
Hyper-redundant manipulators are uniquely suited for confined and hazardous spaces, where traditional robotic systems often fail to perform adequately. These robots, with their numerous degrees of freedom, can navigate the complex geometries found in nuclear fusion reactors, which present unique operational challenges. The proposed control interface not only allows operators to manage these robots more intuitively but also optimizes their configurations to reduce the risk of accidents.
One of the standout features of this interface is its integration of Virtual Fixtures (VFs). These VFs provide haptic feedback, helping operators avoid potential pitfalls such as reaching singular configurations or exceeding joint and torque limits. Capodivento stated, “Using VFs allows the robot teleoperation to be more efficient and effective, keeping it within the joint position and torque safety ranges.” This innovation is particularly significant in the context of nuclear fusion, where the safety of both personnel and equipment is paramount.
The research involved practical tests using the DTT Hyper-Redundant Manipulator, where nine volunteers successfully teleoperated the robot through a haptic device. The results demonstrated that the new interface significantly improved operational safety and efficiency, showcasing its potential for broader applications in the energy sector.
The implications of this research extend beyond nuclear fusion, as hyper-redundant robots could be employed in various hazardous environments, including oil and gas extraction, deep-sea exploration, and disaster response scenarios. The ability to operate these robots safely and effectively from a distance opens up new commercial opportunities for industries that require remote handling capabilities in dangerous settings.
As energy sectors increasingly focus on automation and safety, innovations like the bidirectional control interface developed by Capodivento and her team could revolutionize how we approach remote operations in hazardous environments. The potential to enhance worker safety while improving operational efficiency positions this research as a significant advancement in robotic technology for the energy industry.
