EXPERIMENTAL SYSTEM FOR MEASURING THE BENDING STIFFNESS OF SOFT ACTUATORS BASED ON SERVO DRIVES

Abstract

This article deals with the design, construction, and testing of a new system for measuring the stiffness of soft actuators. These actuators move similarly to living organisms using flexible materials and internal pressure. The study presents a comprehensive method that combines sensors, actuators, and control systems to measure the force developed when the actuator is bent or stretched. Much of the work involves creating an experimental setup that uses a linear axis, force sensors, and programmable controllers to collect accurate data. By studying the behaviour of the actuator under different pressures and movements, the research helps improve the design and use of soft actuators in areas such as robotics, rehabilitation, and intelligent automation. The results highlight the need for accurate measurement tools to make actuators more reliable and useful. The system developed in this study could lead to standard testing methods for soft robotics in the future.
