KUKA LBR Med

Overview

The KUKA LBR Med is the medical-grade variant of the LBR iiwa series, certified to ISO 13485 for medical device manufacturing and IEC 60601 for electrical safety in medical environments. It is available in 7 kg and 14 kg payload variants with 7-axis kinematics and full joint torque sensing, manufactured in Augsburg, Germany. The LBR Med is used in surgical robotics research, medical device assembly, and rehabilitation equipment development.

Key Specifications

• Payload variants: 7 kg and 14 kg
• Reach: 800 mm (7 kg variant), 820 mm (14 kg variant)
• Degrees of freedom: 7
• Repeatability: ±0.1 mm
• Certifications: ISO 13485, IEC 60601
• IP rating: IP54 (autoclave cleaning compatible with appropriate covers)
• Controller: KUKA Sunrise Cabinet (medical-grade configuration)

The medical-grade controller configuration includes additional electrical isolation and fault monitoring to meet IEC 60601 patient safety requirements.

Use Cases

The LBR Med is used as a research platform for robot-assisted surgery systems, medical device assembly under ISO 13485, and rehabilitation robotics research. Universities and medical technology companies use it as the basis for teleoperation systems and minimally invasive surgery research. KUKA supplies it with documentation packs for IEC 60601 compliance integration.

Buying Used

The LBR Med is uncommon on the secondhand market. When units appear, expect to pay £35,000 to £60,000. Medical certification status is critical: verify that the ISO 13485 certificate is current and that the controller configuration has not been modified. Any hardware modification may void the medical certification, requiring re-certification at significant cost.

Alternatives to Consider

• KUKA LBR iiwa 14: The non-medical equivalent, at lower cost, if medical certification is not required.
• Franka FR3: Comparable 7-axis design without medical certification.
• Universal Robots UR5e: Non-medical, but UR's e-Series is commonly used in medical device manufacturing under their own ISO 13485 material certifications.
