Problem statement
How can the uncertainty humans have about robots actions be reduced, using vocal queues.
- Can a vocal queue help reduce the anxiety people feel, because of uncertainty, towards these robots?
- Does the type of voice have influence? That is a more human like voice or a full on (Steven Hawking) robot voice.
Define Uncertainty:
employees working with robots have trouble understanding the robot.
- They do not know how dumb they are at the moment and give a robot a made-up character and intelligents based on what they know.
- Robot is not competing, trying to be better than human(humans can feel like they have to)(Margot)
- humans don’t understand the robot → feel uncomfortable → can't predict its actions → human stops doing his own task (Margot)
- “The ability to estimate engagement and regulate social signals is particularly important when the robot interacts with people that have not been exposed to robotics, or do not have experience in using/operating them: a negative attitude towards robots, a difficulty in communicating or establishing mutual understanding may cause unease, disengagement and eventually hinder the interaction.” https://link.springer.com/article/10.1007/s12369-016-0357-8
(So in short, People don’t understand what the robot is thinking/doing therefore the human is going to put false assumptions on the robot and will act on those assumptions. Or the human will just stop doing his/her tasks.)
Users
Full rundown of stakeholders involved with introduction of robots in warehouse environments. Since there are many different titles for warehouse workers I’m mentioning the ones that I think that need to be distinguished because of their relationship with the robot.
General Warehouse Laborer
- Description: Responsible for general duties involving physical handling of product, materials, supplies and equipment.
- Education: nothing more than a high school diploma needed.
- Much of their work is moving things around in the warehouse but in smaller scales like forklift drivers.
- Relatively safe (employment wise) since they are the jack of all trades in a warehouse
- Logically their interest is against the introduction of robots and if someone was causing inefficiencies because of the robot introduction it would be them. But since they will be the ones working the most with the robots, it makes sense to believe that they will have a positive stance against the robots having higher speaking skills since their job will be easier and they’ll socialize more.
Forklift driver, material handler
- Description: Operate forklifts to move pallets of products, materials, and supplies between production areas, shipping areas, and storage areas, load and unload trailers
- Education: again nothing more than a high school diploma but this time a forklift driver’s license is required and usually experience is required.
- The main group that will be getting replaced for their transporting role but could still remain because of loading and unloading
- Logically their interest is against the introduction of robots since this is the group that is mostly getting replaced, if one stays, their interest are the same as above
Shipping and Receiving Associate, Warehouse Clerk
- Jobs that mostly have to do with overlooking, organizing and preparing the shipments and with speaking with clients to make new deals respectively.
- Education: again, nothing more than a high school diploma but computer handling skills are required
- This group of employees (not employers) will probably be the one that is going to get affected (replaced or change of responsibilities) the least since they do mostly work with human clients or the make higher level decisions
- I believe their interest again should be somewhere in the middle, since their colleagues are mostly getting replaced but they can do their jobs better since the introduction of robots will bring efficiency. Now for them, that their jobs are fairly stable, it makes sense to believe that they will have a positive stance against the robots having higher speaking skills because they will bring better collaboration and thus their organizing tasks will be easier.

Abstract
Introduction(draft)(last edit 2/17)
Industrial robots are taking over more and more tasks in the workforce. Where there were 1.2 million Industrial Robots around the world, there were 1.9 million in 2017 (West, D. M. (2015). The kind of tasks are usually very repetitive (Tamburrini, G. ,2019), jobs that can be seen as very soul-sucking. The robots are making the process faster and cheaper. For example, robots can work 24 hours a day without getting tired. Robots will take in more space in the workforce, robots are getting smarter, cheaper and are starting to take over more complex tasks (West, D. M. (2015). The transition to robot co-workers can often bring troubles due to the human resistance of robots like humans having trouble understanding the robot, the robot working in a different pace (Weiss, A., et al. 2016) or the fear of being replaced by the robot.(Salvini, P. et al. 2010).
In this research we are looking at creating a more efficient and pleasant transition for the human co-workers by giving the robot a human aspect. It will be tested if a voice, and certain usages of the voice can create more trust and understanding of the robot and therefore less resistance. In a study done by Sauppé, A., et al It is already shown how giving the robot eyes can make its functions clearer for humans (2015). Peoples jobs often change due to the introduction of a robot in their work (Salvini, P. et al. 2010). An application of the voice could be explaining the new tasks in a suitable way. This research will mainly focus on industrial robots in warehouses as this is a very common place where robots are taking over tasks(..., ….)

Related work
In the introduction saw that there is not just an increase in the amount of robots, but also in the difficulty of the tasks they perform. In this section we will cover some of the many works that relate to the problems emerging from these increases. We will also cover research that has been done to specific aspects of our problem.
One of these papers focusses specifically on how helpful vocal interaction can be in learning. In the paper “Effects of voice-based synthetic assistant on performance of emergency care provider in training”[1] the researchers measure whether a person can learn how to provide emergency care more quickly if it receives assistance from a voice-based synthetic assistant. This research paper is related to our work in that it shows that a vocal stimulant can help people in situations that are normally difficult for them to deal with. Giving us an indication that our research might result in a positive outcome.
Another paper that is related to ours is the paper called “Intelligent agent supporting human-multi-robot team collaboration”[2]. This paper gives an in-depth explanation of how an intelligent agent can help humans in their collaboration with robots. This article is especially interesting since one of the scenarios they focus on is warehouses. In this scenario the intelligent agent suggest possibly difficult situations for robots, such as a box that has fallen. The human can then judge whether this hinders the robots or not, and possibly change the robots behavior based on this. At some point the paper discusses whether the human found these suggestions helpful or annoying. Another paper that writes about a robot giving feedback to humans is the paper “Inspector Baxter: The Social Aspects of Integrating a Robot as a Quality Inspector in an Assembly Line”[6]. However this paper focusses on the influence movement and facial expressions can have on the social interaction.
The paper “The Social Impact of a Robot Co-Worker in Industrial Settings”[3], gives a discussion of the social phenomena that emerge when a robot co-worker is introduced in an industrial environment. It does this by discussing the relationship that each employee developed with the robot. In the end it suggests some improvements for future robot implementations that would improve further social interactions. This article relates to our problem in that it discusses the problem but in a broader sense. I.e. not focusing on a specific solution. An paper called “Ripple effects of an embedded social agent: A field study of a social robot in the workplace”[4] also discusses these social phenomenon that emerge in a human-robot cooperative industrial environment. However the robots in this paper perform the same basic tasks as the robots in a warehouse. I.e. picking up goods and delivering them to people.
One paper that we found tries to show the importance of movement in the social interaction between human-robot interaction. As cited “they [robots] also need the ability to model and reason about human activities, preferences and conventions. This knowledge is fundamental for robots to smoothly blend their motions, tasks and schedules into the workflows and daily routines of people. We believe that this ability is key in the attempt to build socially acceptable robots for many domestic and service applications”[5] This relates to our work, because it indicates a variable we need to keep track off.

Method
With this method we are trying to see if there is a difference in the interaction with a
warehouse robot when the robot has;
•no communication,
•communicates with lights
•or communicates with voice.
The goal is to get a deeper understanding of human robot interaction focused on voice ques. To do so we will create a scenario were testers have interaction that represents the interaction between man and robot in warehouses.
Task description
• Boxes need to be filled with the assigned combination of objects.
o The test person receives al list with what needs to be in every box
• The robot will deliver the objects.
o From behind a wall, this makes it less clear for the test person how long it will take before its back.
• The Test person will put the object in the boxes.
• The Test person will receive instructions on the robots functions and possible errors.
• When the boxes are ready, the test-person places the boxes on table 2.
•
Light functions:
Direction:
• left, right
Its state:
• green -> correct and ready for next task
• orange -> waiting
• red -> busy, do not interact
Error:
• red flickering
Voice functions
Direction:
• “left, right”
Its state:
• “correct” “ready for next task”
• “waiting” “I still need …”
• “busy, do not interact” “I will be ready in 30 seconds”
Error:
• “There is something in front of the code, I can’t detect it”
• “I do not recognize the path, I can’t proceed”
• “I am stuck”
• “you need 3 block for box 1”

Short Summary:
The goal was to find out what kinds of suggestions the assembly line workers – who actually use the new robotic system – propose in order to improve the human-robot interaction the cooperation with a robot that executes predefined working steps actually impedes the user in terms of flexibility and individual speed. that cooperative robots in a dynamic factory context have to adapt to their human co-workers by taking their individual working steps and speed into account.

Short Summary:
One scenario is that light-weight robot concepts could have an impact on future car manufacturing and on future automation of small and medium size enterprises (SMEs). Such a development could result in modular robots and in control schemes using sensors in the robot arm structure, sensors that could also be used for the implementation of redundant safe control. Introducing highly modular robots will increase the need of robot installation support,
