Resettable Land Anchor Launcher for Unmanned Rover Rescue and Slope Climbing

ICRA 2025

Unmanned planetary rovers have traversed kilometers of Lunar and Martian terrain while performing valuable science. However, they still face mobility challenges including steep slopes and unstable soil that can entrap vehicles, as demonstrated by NASA's Spirit rover. Vehicles on Earth can depend on

Control and evaluation of series elastic actuators with nonlinear rubber springs

IROS 2015poster

Series elastic actuators primarily use linear springs in their drivetrains, which introduces a design tradeoff: soft springs provide higher torque resolution at the cost of system bandwidth, whereas stiff springs provide a fast response but lower torque resolution. Nonlinear springs (NLSs) potential…

Evaluation of decentralized reactive swing-leg control on a powered robotic leg

IROS 2015poster

Animals and robots balance dynamically by placing their feet into proper ground targets. While foot placement controls exist for both fully robotic systems and powered prostheses, none enable the dynamism and reactiveness of able-bodied humans. A control approach was recently developed for an ideal…
