Steps 1, 2, and 3 are covered by Rule 33, Loss and Chaos (although you
might not have though to look there!)  This rule talks about what happens
when the robot does something out on the field, and/or leaves stuff behind.


33 - LOSS AND CHAOS (This rule doesn’t involve a hand-touch.)

• Anything your AUTONOMOUS ROBOT does to your field outside Base (good or
bad) stays that way, unless the ROBOTchanges it. "Accidents," "mistakes,"
and "failures" are the same thing in engineering!

• Cargo the robot loses contact with is left wherever it comes to rest. If
it goes off the table, the ref keeps it.

In other words, anything the robot does (except the few things that are
prohibited) stays as is, unless the robot changes it.  So the answer is
that all of Steps 1, 2, and 3 are allowable.

For Step 4, it is important to read the scoring conditions for each of the
missions.  None of the missions that involve delivering items to the Red
region have the special requirement "touching".  All that they require is
"in".  Brian has done a great job discussing that each individual item
needs to be "in", and also in noting that the Junk Penalty would probably
apply in this scenario.  It's up to the team to decide if incurring a 5 or
13 point penalty is worth the benefits of being able to deliver all the
items with a single container, or whether they'd like to modify their
strategy to avoid a penalty.

bring all the items to base and place them in the container there, but by
placing the container centrally located on the field will shorten the back
and forth distance.

rule 37. None of the items need be touching the mat as that is not
mentioned in rule 37.

be considered "in" if even the front part is "in", each scoring item must
meet the "in" definition on its own. i.e. if the front half "has penetrated
the volume" any scoring items in the front half would count as in, but any
in the back half would not.

rule 10, "Robot") would be a strategic object subject to the penalty (Rule
12, "Strategic objects").
