What is in your Mary Poppins bag

For EDR I have a canvas bag that I keep all my tools and some small parts in, the roboteers call it my Mary Poppins bag. It has things like a spare motor, controller, plastic box with 4 of every size screw over 3/4", gussets, C-Channel connectors, motor tester, custom Auto-Off-Driver switch, battery tester, t handles, wrench, screwdriver, etc. You know, the stuff that in a rush you may need and may not have.

Building my IQ bag with needle nose pliers, small flat screwdriver, screwdriver with a 8/32 diameter point to push connectors out, some assorted cables, spare charged battery, etc. Some 1x1, but mostly the weird connectors (1x3, the ones with square shafts at the end, assorted shafts and the rubber clamps.

Looking to see what else I should keep in the bag.

Long way to say “What’s in your to-go bag?”
