About

Roman Balak is a pioneering researcher in soft robotics, with a focus on magnetorheological (MR) fluid-based actuation, pneumatic systems, and electromagnetic soft motors. His major contributions include the development of bistable valves for MR fluid-driven soft robots, which enable energy-efficient, state-holding actuation without continuous power input—a critical advancement for autonomous soft systems. He also designed a multi-modal pneumatic actuator capable of twisting, extension, and bending, exploiting compliant materials to achieve complex, off-axis motions that challenge traditional single-axis designs. Notably, Balak introduced the first fully-soft synchronous rotary electromagnetic actuator, paired with soft magnetic sensors, achieving high-speed rotary motion that overcomes the limitations of prior soft actuators. His work has garnered significant attention, with his most-cited paper, "Bistable Valves for MR Fluid-Based Soft Robotic Actuation Systems," accumulating 35 citations, and his multi-modal actuator paper reaching 20 citations. Balak’s innovations are foundational for creating fully-soft, untethered robots, and his research continues to push the boundaries of actuation efficiency and motion complexity in soft robotics.
