Question
Meet Dennis, the restaurant service robot
Figure 3: Dennis, the restaurant robot Figure 4: The user interface on Dennis
SingBot Robotics has developed a service robot called Dennis. A large restaurant chain, Gustavo’s, has recently purchased a number of Dennis robots to use as waiters for one of its restaurants in Singapore (see Figure 3).
Customers can give Dennis their orders in two ways:
- They can talk directly to him, in which case Dennis uses pattern recognition to distinguish menu items ordered.
- They can enter their choice directly on a touch screen (see Figure 4).
When the order is ready, Dennis collects it from the kitchen and brings it to the table. Customers can pay by swiping their credit card above Dennis’s card reader.
The marketing manager at Gustavo’s has said that the robots improve the convenience and efficiency of the ordering process. She added, “In their feedback, customers tell us that Dennis makes their experience more memorable.”
The managers at Gustavo’s are considering the introduction of Dennis robots in all their restaurants.
Identify two sensors that Dennis needs in order to operate successfully in the restaurant.
Identify two methods that the marketing manager at Gustavo’s could use to collect feedback from customers about Dennis.
Identify two characteristics of a social robot.
Customers speak to Dennis to give him their orders. Dennis uses natural language processing to understand what has been said to him.
Explain three reasons why Dennis may not be able to understand what customers are saying to him.
