About

Daniel Bruder is a robotics researcher whose work sits at the intersection of soft robotics, control theory, and data-driven modeling. His most influential contribution applies Koopman operator theory to the notoriously difficult problem of modeling and controlling soft robots — flexible, compliant machines whose nonlinear dynamics resist traditional control approaches. His 2020 paper on this topic has garnered over 280 citations, establishing him as a leading voice in data-driven soft robot control and inspiring a productive research thread that continues with his 2024 work on Koopman-based residual modeling. Beyond control theory, Bruder has made foundational contributions to soft robot design and mechanics. His early work on fiber-reinforced elastomeric enclosures (FREEs) produced both continuum models and constitutive frameworks that help researchers predict the complex motions these actuators generate. His 2023 paper on localized stiffening (59 citations) addresses a critical limitation of soft arms — restricted payload capacity — offering a model-based design strategy that meaningfully expands their practical utility. He has also advanced soft robot sensing through IMU-based proprioception and explored novel actuator architectures like the chain-link McKibben muscle. Together, his contributions form a cohesive effort to make soft robots more capable, controllable, and deployable in real-world applications.
