Same, especially when it seemed like the robot arm wasn't adding much to the process? Also the use of pneumatic tools (from I assume, some central compressor) as well as battery powered impact drills. Wouldn't it be so much more economic to use all pneumatic tools? All stations are static, one big compressor feeding a bunch of cheap pneumatic heads versus all the individual battery tools, and managing the batteries, etc. Maybe their tooling changes frequently due to the semi-custom nature of bowling balls?
