Experimental Comparison of Kinematic Task-Priority Control Methods for an Articulated Intervention-AUV

ICRA 2026poster

This work revisits two classical closed-loop inverse kinematics (CLIK) formulations for hierarchical control and investigates their differences in the context of articulated intervention-autonomous underwater vehicles (AIAUVs). The class of AIAUVs consists of free-floating, slender, multi-link vehic…

Passive Multi-Task Compliance Control with Strict Priority through Energy Tanks

ICRA 2026poster

A robot with kinematical redundancy with respect to a main task may perform additional tasks simultaneously with the main one. Often, it is desirable to prioritize the performance of some tasks over that of others. To create a strict priority between the different tasks, meaning the performance of h…

Adaptive Cartesian Position Control with a Switching Strategy for Robotic Manipulator with Mixed Rigid-Elastic Joints

IROS 2025

With the increasing demand for safe and efficient human-robot interaction in industrial applications, robotic manipulators with mixed rigid-elastic joints have gained significant attention, yet their control remains challenging due to inherent parameter uncertainties and complex dynamics. In this pa

Planar Path Following of Underwater Snake Robots in the Presence of Ocean Currents

RA-L 2016

This letter presents a control system that enables an underwater snake robot to converge towards and follow a straight path in the presence of constant irrotational ocean currents. The robot is assumed to be neutrally buoyant, fully submerged and moving in a virtual plane with a sinusoidal gait and
