Magnetic robotic assembly, magnetic robotic system, method for locating a medical device

A magnetic robotic assembly for magnetically locating a medical device comprising:

• a robotic arm,
• a robot base configured to support the robotic arm wherein the robotic arm is movable in a plurality of configurations with respect to said robot base,
• wherein the robotic arm extends at least between a robotic arm basal end and a robotic arm distal end wherein said robotic arm basal end is connected to said robot base;
• a first magnetic source configured to generate a first magnetic field and at least a second magnetic source configured to generate a second magnetic field, wherein the first magnetic field is constant and wherein the second magnetic field is periodically variable,
• wherein the first magnetic source is connected to said robotic arm distal end wherein the first magnetic source is movable integrally with said robotic arm distal end in a plurality of operating positions of the first magnetic source with respect to said robot base to immerse at least one insertion portion of the medical device in the first magnetic field by moving said robotic arm;
• wherein
• said at least a second magnetic source is constrained to said robot base to be arranged in a second magnetic source position which is fixed and integral with respect to said robot base for each first magnetic source position of said first magnetic source.
