RIPS

[Tijn van der Zant]

Hi,

This year it was possible to have an open loop system for the
registration. I think that for next year we should change the rules so
that this is no longer possible, or at least extremely difficult. So
perhaps we could change it so that a robot enters in one room and that
the registration desk is in another.
Even if the previous robot is not out of the room (yet) the new robot
could start to enter so that we can stick to a fast procedure.

I agree.

Yes, we can specify that the robot enters through one door, goes to
the registration desk that is in a different room (optionally
following a team member, but with less points), then exits through the
other door.
Having two arenas this can be easily done in parallel.
Also, as in the past years, I suggest this test to be performed in the
afternoon of the second day of Robocup
(i.e., on July 6, according to the current schedule).

I agree.

Also agreed.

We just specify the locations of the registration in the two arenas, and
then follow the regular test scheme. Teams are assigned to doors, need
enter, need to register, need to leave, finished. Regarding the
schedule, I'm open for everything, as long as RIPS is the first test,
and teams have enough time to "re-register" in case we had issues.

What we should put in the rules is that it is the responsibility of the
teams to take care that their robot is registered and that all issues
are corrected/taken care of. A team where the robot's didn't make it
through the inspection is NOT allows to participate in a test, AND I do
want to run around again (as before the follow-thing in Singapore) to
re-inspect all the robots. It should be the responsibility of the teams
to get their robot inspected in time...

Best,
Dirk

To have a closed loop, we can ask the teams that their robots need to
find the registration desk, putting in it
a color cloth or the symbol that represents the @Home league to help
the robots to find it.

if we don't want to move the registration desk for each team, then the
robots need to find the official that will register them
in the desk and the official just needs to move to a different chair
when a new robot enters the arena.

I don't think that this is necessary. If we have, for example, a kitchen
table and just specify that the kitchen table is the registration desk
_and_ that we are sitting at the registration desk, robot's shouldn't
have a problem with getting there, approaching the table to be closer
than, e.g., 1.5m, being oriented towards to that table and not crushing
into table, chairs, or us. Everything else just makes it unnecessary
complicated in my opinion.

In principle, we only want:
1.) robots entering (able to move)
2.) stand still or getting inspected and
3.) move further so that we can check the emergency button(s)

I guess Tijn's point when starting the discussion was that the we only
had a path of something like 2m from the door to the registration desk,
and that the movement of many robots was looking like turning X degrees,
moving Y meters, turning Z degrees, and that's in fact awkward. As long
as we have a "real path" from both doors to the registration desk, we're
all fine I guess. There's definitely no need for "searching" for the
registration desk, especially taking into account the performance of
teams in the last years when searching for objects ... lost&found still
seems to be somewhat unsolved :)

Cheers,
Dirk

I agree.

In addition, we don´t want to change very much the rules this year.

We should make certain that on day 1 the scenario is fully up and
running, though
