Abstract:
Assistive robots for elderly and disabled people
are being developed to uplift the living standard of the people.
The idea of realizing the dream for a robot assistant obviously
depends on the availability of human-human like interactions
in human-robot interactions also. Humans prefer to use voice
instructions, which have uncertain information such as “very
little”, “far” etc. in their daily interactions. Therefore, the ability
of a robot assistant to understand the uncertain information is
crucial. Therefore, our study proposes a method to interpret fuzzy
linguistic information related to distance in user commands by
evaluating the spatial information of the surrounding environment.
Fuzzy logic based fuzzy linguistic information evaluation
system (FLIES) has been introduced to interpret the fuzzy
linguistic terms in user commands by analyzing possible movement
restrictions in the surrounding environment. The proposed
method has been implemented and tested on a Pioneer 3DX
mobile robot. The experiment has been conducted in two different
indoor environments and the experimental results of the system
are presented.
