Innovative robotic catheters that are soft, flexible, and controlled by magnets have the potential to revolutionize minimally invasive surgical procedures in critical areas such as the lungs, brain and pancreas, which currently pose significant safe access challenges using existing technology. These
Despite the increased interest in robotic systems designed for bronchoscopy, the influence of the bronchial tree dynamics remains relatively unexplored. To enable robotic solutions to perform successful autonomous navigations whilst minimizing contact with the internal anatomy, they must be capable
Drawing inspiration from natural growth and movement strategies, vine robots possess exceptional passive shape-forming abilities, enabling them to deform around obstacles. However, an intrinsic lack of active steering limits their capacity to control their growth trajectory. This letter considers th
Simulation represents a key aspect in the development of robot systems. The ability to simulate behavior of real-world robots provides an environment where robot designs can be developed and control systems optimized. Due to the use of external magnetic fields for actuation, magnetic soft robots can
Soft and flexible magnetic robots have gained significant attention in the past decade. These robots are fabricated using magnetically-active elastomers, are capable of large deformations, and are actuated remotely thus allowing for small robot size. This combination of properties is appealing to th
This letter discusses a novel static control approach applied to magnetic soft continuum robot (MSCR). Our aim is to demonstrate the control of a multi-magnet soft continuum robot (SCR) in 3D. The proposed controller, based on a simplified yet accurate model of the robot, has a high update rate and
Fully soft continuum magnetic (FSCMs) microrobots with highly deformable structures have emerged as a potential solution to robotically controlled endovascular interventions. The microrobot's structure is made of magneto-responsive material, which offers full body control under a magnetic field inst
Localization of magnetically actuated medical robots is essential for accurate actuation, closed loop control and delivery of functionality. Despite extensive progress in the use of magnetic field and inertial measurements for pose estimation, these have been either under single external permanent m
Flexible catheters are used in a wide variety of surgical interventions including neurological, pancreatic and cardiovascular. In many cases a lack of dexterity and miniaturization along with excessive stiffness results in large regions of the anatomy being deemed inaccessible. Soft continuum robots
Soft continuum robots have the potential to revolutionize minimally invasive surgery. The challenges for such robots are ubiquitous; functioning within sensitive, unstructured and convoluted environments which are inconsistent between patients. As such, there exists an open design problem for robots
Continuum manipulators are flexible robots which undergo continuous deformation as they are actuated. To describe the elastic deformation of such robots, kinematic models have been developed and successfully applied to a large variety of designs and to various levels of constitutive stiffness. Indep
