Magnetic resonance compatible robot system

A magnetic resonance compatible robot system, comprising a robot body (4), a control cabinet (1) and cables (6), the control cabinet (1) is used for controlling the operation of the robot body (4) via the cables (6), wherein the robot body (4) comprises motors (11) and encoders (12), each of which is externally provided with an insulation film (30), a metal shielding layer (32) and an insulation shell (31) in sequence, and the cables (6) comprise communication cables (15, 16) for communication and motor drive cables (17, 18) for motor drive,

• wherein the motor drive cables (17, 18) each comprise a wire (27), a wire insulation layer (28) arranged outside the wire (27), a motor drive cable inner shielding layer (26) covering the wire insulation layer (28), an outer shielding layer (25) arranged outside the motor drive cable inner shielding layer (26) and an outer insulation layer (24) arranged outside the outer shielding layer (25) from inside to outside in sequence;
• the communication cables (15, 16) each comprise a twisted pair (29), a communication cable inner shielding layer (41) arranged outside the twisted pair (29), an outer shielding layer (25) arranged outside the communication cable inner shielding layer (41) and an outer insulation layer (24) arranged outside the outer shielding layer (25) from inside to outside in sequence, wherein each wire (27) of the twisted pair (29) is externally provided with a wire insulation layer (28);
• and
• the motor drive cable inner shielding layer (26) is a double shielding layer of metal foil and metal braid wire mesh, the communication cable inner shielding layer (41) is metal foil, and the outer shielding layer (25) of the motor drive cables and the communication cables is metal braid wire mesh.
