AUTOMATION ROBOTICS “You’re going to need different capabilities at different times. For instance, if I’m doing something on an engine, I might need to be able to lift and support 150-200 pounds; but I may also need some very fne manipulation of small fttings to remove that part. So
I probably won’t have a bipedal two-armed robot. I will have a robot that can support itself either on a rail or a bulkhead for that heavy lift, and it may have four arms, two gross movement arms that can handle the heavy lift, and then two fne skilled arms that are doing the fne fxture movements.” – Trey Taylor, Director of Digital Innovation,
