Human-Robot InteractionThere is a problem with clarity in the question – I've been assigned a robot, and the question accepts that, but the question asks "for which you design your robot." The robot has already been designed, so the question is nonsensical. There is also the claim that terms in capital letters are defined in Looijie – this is also false. Those terms are used in that paper, and form the basis of it, but they are not explicitly defined in that paper. The instructor clearly is not very good at English and this is going to put the paper at risk because of it.

1. The main objective for which Sanbot designed the Elf appears to be for "Hi-level (sic) scenarios in the hospitality, retail and public service…" The sentence is not completed – Sanbot needs a copywriter in the worst way. There is no other information about what the robot actually does. My application will be to give this robot function, in this case in a supermarket. The Elf will be programmed to assist shoppers with basic questions about the location of goods or service areas within the store. It will do this by accessing both basic store layout information (i.e "where are the bathrooms?"), but also specific SKU information (i.e. "where are the cans of Spam?"). If a good is out of stock, the Elf will be able to tell the customer that as well.

The Elf is capable of voice interaction, and 3D dynamic perception, which allow it to interact with human shoppers and respond to 1-on-1 questions of a dynamic nature. The Elf's touchscreen can help shoppers to search for specific items, and then display the location of the item or shopping area (i.e. deli) on a map of the store.

2. A use case specifies a specific situation where the methods will be used to meet an objective (Looije , et al, 2017). A common use case would be a customer who wishes to find an item in the supermarket. We know that each supermarket...

The Elf can assist customers to find everything that they want. The Elf will have access to a store map, both with different departments and with different SKUs.
A customer would present to the Elf and make the query, eg. ("I can't find the 10kg bags of basmati rice."). The Elf would be programmed to check a) if there are any in stock and b) where they are located within the store. The Elf would then respond both verbally ("10kg bags of basmati rice are located in the middle of aisle 7") and visually using the robot's touchscreen to show the location visually. The entire transaction can be done on the touchscreen as well – the Elf can be programmed to interact in multiple common languages, to serve customers who do not understand the default language.

3. The Sanbot Elf is capable of multiple interaction patterns. It can respond to speech, but it also has a touch screen that can be used for interaction. The use case above describes the ability to use the touchscreen to handle non-default languages, or to serve the hearing impaired. It can also be used if verbal commands are not working (for example if the customer has a thick accent the robot cannot understand).

Interaction patterns are means by which the Elf will understand, respond and be understood. It will need to be programmed with verbal fluency in at least one language, preferably all of the major languages in the region, and can be programmed with a broader set of languages for visual, on the touchscreen. The Elf will need to be able to understand what language is being presented to it. Further, the different goods and departments within the store will need to be listed in each language, so that the Elf can find the good (eg 10kg of basmati rice will need to be understandable if presented to…
