I've seen some videos about zipline, it looks like they've (you've?) got some *really* clever system-usability stuff worked out. (Yes, we have an internal #robots slack channel where we gossip about all the *other* robot and autonomous systems companies out there :-)
Best of luck getting up to speed... when I started at RightHand I ended up digging back to computer graphics work I did in the 80s (because all of the raw 3d perspective transform matrix math that noone does anymore (because GPUs exist) is basically the robot arm kinematics math too)... and spending a lot of time on wikipedia after every conversation with the Math People (though that did eventually fade - and I'm senior enough and credible enough on the stuff I was expert on that posting a weekly "Things I needed WikiPedia for" report was both funny and eventually useful to the more junior people we brought onboard later.)
Wow!
