Modular Magnetorheological Actuators Controls

Since its foundation in 2013, Exonetik has been developing and manufacturing magnetorheological (MR) actuator systems that enable novel functionalities to satisfy unmet customer needs. Exonetik’s patented actuators offer a unique combination of torque-density, high bandwidth, superior back-drivability, low-cost and aerospace-level reliability. To reach its ambitious goals, Exonetik has built several strategic relationships with major OEMs in the aerospace and automotive sectors and now wishes to repeat the process in the robotics’ field.
In 2018, Exonetik started exploring collaborative robotics, where it saw a unique opportunity for its MR actuators. In this field, Exonetik initially investigated the potential of remote actuator systems through the development of various prototypes (e.g.: 3 degree-of-freedom – DOF – wearable hydraulic robotic manipulator and teleoperated cable-driven arms). While the performance of these prototypes was excellent, this approach leads to unnecessary complexities (e.g.: routing) for 6 DOF robotic arms. In 2020, Exonetik thus developed its first modular MR robot actuator, and in 2021, its first 6 DOF robot for human-robot interaction. The modular MR robot’s promising performance has led compagnies to sign agreements with Exonetik to develop robotic arms for various robotics tasks.
