Best multi-tool for robot/field use

[InFlight]

Foster- Your sizes seem like they are for very small fasteners
Hex Key 5/64" is for a #2 Cap head
Hex Key 3/32" is for a #4 Cap head
11/32 Nut Driver is for a #8 Nut

If your team has standardized on one or two fastener sizes it makes it easier to carry less items, but the correct specialized tools for the job rather than a multi-tool.

Klein or other Hex Key Folding Set - Make sure it has 7/64, 9/64, 5/32 and 3/16 to cover all standard cap heads #6-1/4 in size.
