Why do we want to introduce grasping here?

We should not remove person recognition (e.g. describing the guest) for another recognize object.
There are other stage one tasks to show object recognition.

The gaze is currently very simple (straight during interaction, down during navigation). I also dont want any more of "please step to my left so i can introduce you" for introduction.

The improvement should be making sure the recognition/tracking of humans really works e.g. follow the head while the person moves. Ideas:

• the person simply paces from left to right side of robot during introduction
• another guest blocks the gaze direction so the robot has to adjust its position to see the guest
• person hides behind a lamp
• a conversation with two people at the same time -> look at the speaking person

We will not collect any logs. Robot should speak loud and repeat on request.

Robocup wants to move away from 'state machines' in tasks, the procedure makes the task too static. e.g. why smalltalk at specific points.

I really like this update to receptionist!
Just a couple of things:

- the robot shows both guests where the drinks are and detects if their favorite drink is available
I really like this, it allows teams to show object detection! i would not add bonus points for picking up the object. There is already picking objects in a lot of other tasks. no need for this also in receptionist.

I think describing the first guest to the second guest is weird because if I look to the second guest and point to the first guest, why do i need to describe it?

I think with the new additions asking for: "one or two interests and a profession to ask about" seems a bit much, let's just ask for one hobby for now, if it goes well than we can add more next year.

+ 50 pts identify favorite drink
and add a new one +"50 show where drink is" similarly to what is done in DEM where the robot has to point or show in the face where the drink is. As a guest if a robot tells me there is a drink in a cabinet, I do not want to know there is a drink and still have to look for it, i want the robot to tell me where the drink is.

The door opening points are VERY misadjusted. Opening the door is much more complex than opening the cabinet door in storing groceries, and teams get 200 points for the cabinet door and 100 points for the entrance door. In the entrance door you have to identify the handle, pull down the handle, pull the door, ... whereas the cabinet door is much simpler. I believe no team even tries to attempt this (even though a couple of teams showed in their qualification videos from last year they could open doors), means that the number of points doesn't compensate the risk that is attempting to open the door.

personally not a fan of the small talk...

The way you are thinking, we don't have to do any introductions to the host (we don't even have to detect or know who the host is) and just have to introduce the first and second guest right?

I don't also agree with the speaker log... the robots must talk clearly, loudly and find solutions to have their messages understood like show in a tablet...

I think the people talking should always be making some kind of movement... robots should only get points for looking at the person if it is dynamically real time adjust to the person whom it is talking to. I believe one small step to the left and the right should be enough to check this... we often see robots looking to the person coordinates and if the robot moves, it still looks to the place where the person was.

  you have +50 looking at the person talking twice

@LeroyR

Firstly thanks for the feedback,

• we can absolutely remove the optional goal of grasping

"We should not remove person recognition (e.g. describing the guest) for another recognize object. There are other stage one tasks to show object recognition."
i removed that point because it seemed very unnatural to just state perceived attributes. however we can keep that goal.
it surely is important for a human service robot to detect attributes of humans

"the person simply paces from left to right side of robot during introduction"
The suggestion is great and i would add that. I actually thought that this was already part of the challenge. But you are right it should be described in the text.

" another guest blocks the gaze direction so the robot has to adjust its position to see the guest"
another person blocking the guest is pretty difficult to implement because usually the robot and guest are standing very close
during the introduction and face each other directly. Additionally this scenario rarely happens in real life. when you
stand close to another person and talk to them other people usually move around you because it is very rude to go in between.
But that we could add. That behind the guest other people move around. to see if the robot loses focus because of the background humans.

" person hides behind a lamp"
What do you mean with hide behind a lamp? does that mean the robot has to find the guest that it should guide through
the arena?

"a conversation with two people at the same time -> look at the speaking person"
Interesting idea. that could be included when both guests are sitting in the living room.
However and this includes your last point with not collecting any logs: the Robocup arena is to noisy because it is a big event.
in Eindhoven there was a band playing during the challenges. Therefore it will never simulate a real household environment which is fine but we need to adjust the challenges and ratings accordingly.
That is the reason why i would log conversation and why i think it is difficult for the robot to detect who is speaking.

Thanks for the feedback,

"Let's just ask for one hobby for now, if it goes well than we can add more next year"
sounds great!

"I think describing the first guest to the second guest is weird because if I look to the second guest and point to the first guest, why do i need to describe it?"
I actually removed that already or did you answer @LeroyR with this?

"i want the robot to tell me where the drink is."
good idea i will add that.

"The door opening points are VERY misadjusted"
i agree that door opening is much more difficult than opening a cabinet door. I did not raise the score because
i also read some backlash about raising the points because it is a recurring task. I would also raise the points
and maybe lower the score for cabinet opening. However i think some more opinions about that from other Members would be great to get a better view on this issue.

" The way you are thinking, we don't have to do any introductions to the host (we don't even have to detect or know who the host is) and just have to introduce the first and second guest right? "
well you have to detect the host to find a free spot in the living room. And if one of the guests interests
match with the hosts interests the robot should look at the host and guest while telling the similarity.

" I don't also agree with the speaker log... the robots must talk clearly, loudly and find solutions to have their messages understood like show in a tablet..."
i have answered that issue earlier. but in addition to that answer: To log what the robot says was also meant as a help for the referee. Because as a referee you need to keep many things in mind and sometimes you miss details. With logs you can check later.

For the speaker log, I agree with speaking louder (External speaker is allowed) and encourage displaying text at the same time, however disagree with the log file to check it later. Creating the log might cause cheating. If the guest does not understand, the robot should repeat to continue the conversation.
In the current DEM for manipulation, the robot has to show the recognition result while the robot is doing the task, rather than show the result later. I think the same idea should be applied to audio too.

For door opening, in my opinion, 200 bonus is big enough so we might consider reducing the SG bonus.

For

Before reaching the living room, the robot gathers one additional piece of information about the guest at a freely chosen moment.

Regarding @LeroyR's comment,

why smalltalk at specific points.

I like to propose the idea that the guest to speak about them in their own time and way.

The guest might talk about them at their own time, or the robot might ask about the guest if it is required.

I think a kind of question generator will be helpful for the guest, now the guest has to memorize their name, hobby, and profession and it might confusing without a memo or something.

Do we provide a list of names, professions, and hobbies? I think it is not necessary.

I think you should standardize the usage of the terms: "hobby" and "interest" as it may be confusing, I personally think interest is the way to go.

I think this (\scoreitem[2]{10}{tell position of favorite drink}) has to be more significant: it is 3 times less than to look in the direction of navigation which is basically just moving the neck forward...

I have to insist that opening the door is too undervalued, maybe put is 125. It is just disappointing that no teams has ever opened a door and a significant number of teams show that they can do it in their qualification videos...

Apart from these I think everything is OK
