MI-RO
Fujitsu has created a robotic machine which aims to help a surgeon directly at the operating table where there is not enough space. Mi-Ro is one of the surgical robotic systems that has compact, slim, and lightweight arms which can perform a variety of functions, ranging from guiding a laser unit for accurate and meticulous separation of bone tissue, setting holes for bone screws for orthopaedics, and endoscopic guidance for minimal invasive surgeries. The robot weighs 9.8 kilograms, with seven joints, has a maximum payload of 30 N, and has a maximum arm length of 1.1 meters.
Mi-Ro is equipped with seven torque-controlled joints, which allows a more adaptable operating room setup and avoids it crashing into other robots or equipment. A serial kinematics of human-like arms have been developed and optimized, with seven DOF. This gives the robot an arm of joint morphology group - a dedicated shoulder, upper arm, elbow, forearm, and wrist - each group with intersecting axes.
Aside from the sophisticated motor gears and integrated torques in the arm, Mi-Ro is also installed with position sensors, power electronics, and programmable logic electronics in each joint.
