1 FANUC Collaborative Robot Technology and GM Applications Greg Buell Fanuc America Chris Ihrke General Motors

2 Spare Tire Application Perennial ergonomic and safety concern Productivity issue Wanted a low impact automated solution Interested in using a collaborative robot, but reach and payload requirements were outside the capabilities of available products Before

3 Robot Specification Payload capabilities Passive safety features Active safety features Configurability

4 Payload Capabilities Initial Requirements Collaborative robot with payload specification to handle spare tires Wrist load ratings capable of standard industrial tooling Reach ability to be able to stack the tire carts

5 Passive Safety Features Color Distinct Green Color and soft foam Pinch Points Brackets and sharp edges External Considerations The robot had to have a visual distinction from other robots in the plant Standard robot features needed to be safeguarded against Inherent industrial robot hazards needed to be mitigated, pinch points, hard casing, etc Pinch Points Eliminated

6 Active Safety Features Collaborative Mode Maximum 250mm/s Stop Built-in Safeguards Speed limited to 250mm/s in contact stop mode Multiple contact stop force settings can be adjusted on the fly Push-to-escape on J1 and J2 for operator interaction Hard contact retract feature to help relieve quasi-static force Push J1 Retract Push J2

7 Configurability System Configuration Multiple contact stop force settings Ability to change forces based on safety inputs or specific cell locations Push to escape force and speeds configurable Monitoring I/O for the safety features for cell awareness Payload change limits for safe part picking/dropping

8 Safety System Architecture Safety rated force monitoring Integrated into DCS Third party certification

9 Safety Rated Force Monitoring Collaborative Sensor Safety rated collaborative sensor mounted inside the robot Active force reading as well as current setting indicator Internal checking system constantly monitoring the sensor for correct performance

10 DCS Integration Dual Check Safety Collaborative Robot settings integrated into DCS Category 3 PL.d safety rated All configurations are password protected DCS Broadcast safety signature includes collaborative settings for plant wide safety monitoring systems DCS is TUV certified to meet industry standards

11 3 rd Party Certification Force and Power Limiting TUV certified to meet a maximum contact stop force setting up to 150N Testing according to 2006/42/EC ISO :2011 EN ISO :2008 (CAT3,PLd) IEC :2008

12 Other Hazards Gripper Soft covering Extended diameter Finger details retract into cast rubber bumper Gravity Monitoring of cart in position Monitoring of stack height Cross-checking of stack counts with sensor measurements Trip Hazards

14 Spare Tire Application GENERAL MOTORS Getting closer to the machine Some unlucky human at GM s Orion, Mich. assembly plant has had the dull, backbreaking job of pulling spare tires off a conveyor and stacking them based on their assigned vehicle. The factory s first collaborative robot, which arrived in January, was ordered to stack tires. The robot is now considered part of the team.
