Accurately Modeling the Output Torque and Stiffness of Ankle-Foot Orthoses with a Compliant Linkage Model

David J. Lam, Nikko Van Crey, Elliott J. Rouse

ICRA 2025

The stiffness of passive lower-limb exoskeletons and orthoses governs their assistance. A common practice in the design of these systems is to assume the stiffness of the device is determined only by the intended elastic element (e.g., spring), while the structural components, human attachments, and

Robust capture of unknown objects with a highly under-actuated gripper

Paul E. Glick, Nikko Van Crey, Michael T. Tolley, Donald Ruffatto

ICRA 2020poster

Capturing large objects of unknown shape and orientation remains a challenge for most robotic grippers. We present a highly under-actuated gripper well suited for this task. Prior work shows two primary limitations to these grippers: the grip force of each link tends to decrease as the number of lin…
