23 Computer Vision News predict the magnetic field and determine the position of the permanent magnet. However, it is an approximation with a lot of inaccuracies. The team would need a more complex and computationally less efficient model to be more accurate, so it is a trade-off. Magnetic tentacle actuation principles. Description of magnetic steering based on field-magnetization alignment (1) combined with tip-dragging in a tangential direction to the anatomy’s centerline (ν) realized via gradient pulling and relative translation (δ) of the external permanent magnets (EPMs) (2). This thought leads us to a fundamental question: why use magnets in the first place? Pietro says the most viable alternative would be small tendons integrated into the catheter. However, these would have implications for its size. “If you integrate tendons in the catheter, then you need a larger diameter and a stiffer device,” he explains. “With magnets, you just need to embed magnetic particles. Then, the magnetic force and torque for actuation and steering come from outside, so your catheter can be soft and thin.” STORM Lab operates at the intersection of robotics and medicine, comprising a diverse 30-strong team of postdocs, PhD students, and lecturers. They are all robotics engineers with varied backgrounds, including electronic and mechanical engineering and computer science. “It’s also crucial for us to work with clinicians,” he emphasizes. “We have many collaborators here in Leeds and in the US, but it’s key that we work with doctors on a daily basis.” Its magnetic colonoscopy robot, licensed to a University of Leeds spin-out company, Atlas Endoscopy, is pioneering technology poised to transform this common medical procedure. Having already completed human trials, Pietro is optimistic: “I would say keep an eye on Atlas Endoscopy,” he teases. STORM Lab is looking for new talent. If you think you have what it takes, you may be joining them on the next leg of their journey of discovery! Pietro Valdastri and STORM Lab
