38 Best Paper Award consumption and need for cooling make that very costly. We started investigating mathematically and theoretically – what can one, two, three, or more permanent magnets do? Luckily, we stopped at two because I don’t think Pietro would have paid for ten robots! ” Michael adds: “ We’re exploring the possibility of using more robots in the future, but we have already maximized how much we can control the magnetic field in our workspace with this platform. More robots might allow the development of new devices that we haven’t even thought of yet, but we’re focusing on our two-robot system for now. ” Being picked for a Best Paper Award is a huge achievement and no mean feat, but Michael has an idea of what might have influenced the judges’ decision. the anatomy with multiple magnets along the length of the catheter. But the team discovered that if this was not matched with the ability to control the magnetic field in a more convoluted way, the degree of shaping does not improve. The team met with Pietro’s colleagues from the University of Toronto , who were working on the ability to control the magnetic field in a more convoluted way with eight degrees of freedom, but within a relatively small magnetic workspace, which did not apply to their case. How did they solve it? “ Two years of hard work! ” Giovanni laughs. “ I thought,what ifwe take that ideaof being able to control these degrees of freedom and we scale it up. The way to scale it up usually is to use permanent magnets with systems of coils , but the energy Michael Brockdorff Giovanni Pittiglio
