An Architecture for Person-Following using Active Target Search
[article]
2018
arXiv
pre-print
Preserved Fulltext
This paper addresses a novel architecture for person-following robots using active search. ...
Toward this end, an active target searching capability, including prediction and navigation toward vantage locations for finding human targets, is proposed. ...
This information can be used as an important clue for robots to follow or search for target objects. To compute where a robot is headed, a person-following algorithm is described in Algorithm 1. ...
