Elastic Structure Preserving Control for Compliant Robots Driven by Agonistic-Antagonistic Actuators (ESPaa)

RA-L 2021

The regulation of the link positions of compliant robots, damping out undesired link oscillations while preserving the system's inherent elasticity is still a challenging task in practical applications. This task becomes even harder to be tackled in the case of compliant robots driven by agonistic-a

Time Generalization of Trajectories Learned on Articulated Soft Robots

RA-L 2020

This letter proposes a framework which is able to generate a sequence of three-dimensional human dance poses for a given music. The proposed framework consists of three components: a music feature encoder, a pose generator, and a music genre classifier. We focus on integrating these components for g

Time-Optimal Trajectory Planning for Flexible Joint Robots

RA-L 2020

In this letter, a new approach is proposed to optimally plan the motion along a parametrized path for flexible joint robots, i.e., robots whose structure is purposefully provided with compliant elements. State-of-the-art methods efficiently solve the problem in case of torque-controlled rigid robots

Trajectory Tracking of a One-Link Flexible Arm via Iterative Learning Control

IROS 2020poster

Trajectory tracking of flexible link robots is a classical control problem. Historically, the link elasticity was considered as something to be removed. Hence, the control performance was guaranteed by adopting high-gain feedback loops and, possibly, a dynamic compensation with the result to stiffen…

Stiffness Bounds for Resilient and Stable Physical Interaction of Articulated Soft Robots

RA-L 2019

It is widely recognized that impedance modulation is a key aspect in applications in which robots significantly interact with the environment or humans. Either active impedance controllers or actuators with passive variable impedance can be exploited to modulate the impedance. However, methods capab
