About
Robb Colbrunn is a biomedical engineer and robotics researcher whose work spans two interconnected domains: biomechanical robotics and musculoskeletal systems research. Early in his career, Colbrunn made foundational contributions to the field of pneumatic actuation, developing influential models of braided pneumatic (McKibben) actuators that captured their nonlinear, muscle-like force-length properties — work that earned over 100 citations and shaped the design of biologically inspired legged robots. His 2002 robotic leg system, actuated by artificial muscles with independently controllable stiffness, demonstrated practical forward locomotion and remains a landmark in compliant robotic design. Colbrunn subsequently applied his engineering expertise to orthopaedic biomechanics, developing sophisticated robotic testing systems capable of simulating full physiological joint loading in vitro. This platform enabled rigorous investigation of spinal constructs, ACL mechanics, and rare conditions like Bertolotti syndrome, generating a body of work that directly informs surgical decision-making. His studies on lumbar fusion, craniovertebral junction stability, and ACL femoral insertion kinematics reflect both technical precision and clinical relevance. With multiple papers exceeding 30–40 citations and collaborative work spanning robotics, neurosurgery, and orthopedic surgery, Colbrunn exemplifies the impact of translational engineering research in advancing human health.
