A robot is proposed that can proactively approach pedestrians to initiate interactions for services. The robot uses public and social distance zones to choose targets that are not busy and can be approached frontally. It coordinates its body orientation and timely responses based on the person's reaction. Testing in a shopping mall showed the proposed approach technique was more successful than a simple method, with success rates of 55.9% versus 35.1% respectively.
A robot that approaches pedestrians
- 1. A ROBOT THAT APPROACHES PEDESTRIANS ABSTRACT When robots serve in urban areas such as shopping malls, they will often be required to approach people in order to initiate service. This paper presents a technique for human–robot interaction that enables a robot to approach people who are passing through an environment. For successful approach, our proposed planner first searches for a target person at public distance zones anticipating his/her future position and behavior. It chooses a person who does not seem busy and can be reached from a frontal direction. Once the robot successfully approaches the person within the social distance zone, it identifies the person’s reaction and provides a timely response by coordinating its body orientation. The system was tested in a shopping mall and compared with a simple approaching method. The result demonstrates a significant improvement in approaching performance; the simple method was only 35.1% successful, whereas the proposed technique showed a success rate of 55.9%. EXISTING SYSTEM Robots have started to move from laboratories to real environments, where they interact with ordinary people who spontaneously interact with them. Robots have been tested in guiding roles in museums and supermarkets. Social robots, such as receptionists and tutors, have been developed to interact like humans, communicating socially with people. The “initiating interaction” is one of the fundamental capabilities of human–robot interaction for such robots. That is, the initiating interaction would be commonly useful among these robots, while each of them would engage in task-specific interaction for each individual application after initiation. Although many robots are equipped with the capability to invite people into an interaction, these robots only passively wait for people to approach them.
- 2. PROPOSED SYSTEM In our proposed system, a “mobile” robot can approach people to initiate interaction. This way of providing services is more proactive than waiting, since it enables robots to find and assist people who have potential needs. For instance, imagine a senior citizen who is lost in a mall. If a robot were placed in the mall to provide route directions, it could wait to be approached for help; however, people might not know what the robot can do, or they might hesitate to ask for help. It would be more appropriate for the robot to approach and offer help. Our study presents a method to deal with this novel way of initiating interaction. A robot’s capability to approach people is important for a number of applications. We believe that one promising application is an invitation service; a robot offers shopping information and invites people to visit shops, while giving people the opportunity to interact with it, since robots remain very novel.
