Navigating tortuous anatomical pathways, such as the aortic arch, requires continuum robots capable of complex three-dimensional deformations. Existing designs are often limited to specific curve families, and extending their shape capabilities usually increases mechanical complexity and system size
This letter introduces a novel method of non-rigid motion compensation for in situ bioprinting. Most bioprinting platforms use open-loop systems, but it raises concerns about patient safety and suboptimal wound coverage in case of patient motion. To handle these issues, our method integrates an RGB-…

In this paper, a method for 3D non-rigid motion estimation of a surface using an RGB-D camera in eye-in-hand configuration is presented. The eye-in-hand configuration eliminates errors typically associated with camera-end-effector calibration, and is thus desirable for task on moving surfaces such a…
The present letter proposes a predictive path following control (PPFC) that controls 5 degrees of freedom (DoFs) of the end-effector while the remaining (decoupled) translational DoF should be controlled by an external controller. This PPFC is particularly useful for the path following on surfaces w
In this paper, the design of a new variable stiffness spherical joint for MR-compatible robotics is presented. It is based on the use of prestressed cable-driven mechanisms in singular configurations to provide large stiffness variation ranges, including zero stiffness configuration as required by t
Needle placement errors can mitigate the effectiveness of the diagnosis or the therapy, sometimes with catastrophic outcomes. Previous design of a simplified model for needle deflection estimation was motivated by the clinical constraints of ARCS (Abdomino-pelvic Robotic-driven slightly flexible nee…
