Wrench-Aware Admittance Control for Unknown-Payload Manipulation
Hossein Gholampour, Logan E. Beaver
Unknown payloads can strongly affect compliant robotic manipulation, especially when the payload center of mass is not aligned with the tool center point. In this case, the payload…
Optimal Control and Structurally-Informed Gradient Optimization of a Custom 4-DOF Rigid-Body Manipulator
Brock Marcinczyk, Logan E. Beaver
This work develops a control-centric framework for a custom 4-DOF rigid-body manipulator by coupling a reduced-order Pontryagin's Maximum Principle (PMP) controller with a physics-…
A Long-Duration Autonomy Approach to Connected and Automated Vehicles
Logan E. Beaver
In this article, we present a long-duration autonomy approach for the control of connected and automated vehicles (CAVs) operating in a transportation network. In particular, we fo…
Trajectory Tracking with Reachability-Guided Quadratic Programming and Freeze-Resume
Hossein Gholampour, Logan E. Beaver
Many robotic systems must follow planned paths yet pause safely and resume when people or objects intervene. We present an output-space method for systems whose tracked output can…
Mixed Traffic: A Perspective from Long Duration Autonomy
Filippos Tzortzoglou, Logan E. Beaver
The rapid adoption of autonomous vehicle has established mixed traffic environments, comprising both autonomous and human-driven vehicles (HDVs), as essential components of next-ge…
Mass-Adaptive Admittance Control for Robotic Manipulators
Hossein Gholampour, Jonathon E. Slightam, Logan E. Beaver
Handling objects with unknown or changing masses is a common challenge in robotics, often leading to errors or instability if the control system cannot adapt in real-time. In this…
