The rapid development of ergatic systems, which integrate a human operator and automated devices into a single functional environment to ensure efficient operation in complex and aggressive man-made conditions, leads to a number of problems during their operation in extreme conditions. This list includes high levels of thermal exposure to the operator and technological equipment, humidity, chemical or radiation hazards, as well as the operator’s psychological stress and cognitive overloads. In such situations, robotic manipulators play a key role in ensuring the safety and stability of the technological process, as they can compensate partially or completely for human factor limitations. Among them, manipulators with translational links are of particular interest. They demonstrate high design and operational advantages for solving tasks where high linear positioning accuracy, simple control algorithms, and reliability in extreme conditions are required. The direct separation of operator functions and automation reduces the psycho-physiological workload, minimizes the risk of errors, and enhances the system ergonomics. Developing this class of ergatic systems requires an interdisciplinary approach that integrates engineering psychology, mechatronics, and materials science. Testing the prototype shows high ergonomics and reliability of manipulators with translational links, which confirms their promise for use in ergatic systems operating in aggressive conditions under stress-inducing influences on operators.
