Expressing attention requirement of a floor cleaning robot through interactive lights


Cleaning robots are used to cater to the demands in both domestic and industrial premises.

Much of the research work is being conducted to improve functionalities and efficiency of cleaning robots.

Users of these robots prefer human-friendly interactive features in these functional robots.

Therefore, the focus of the research work in the area of cleaning robots has been drifted from improving core cleaning related functionalities to implementing human-friendly interactive features in recent years.

The existing floor cleaning robots do not possess the ability to express their state to users. 

Lack of expressiveness is one of the major factors that degrade human-robot interaction.

Therefore, this paper proposes a method to express a floor cleaning robot's attention requirement to its users.

The attention requirement of the robot in a situation is determined by a fuzzy inference system that analyzes the bumping level and experience of attention level requirements.

The requirement of attention is expressed to users by varying the color of lights attached to the robot.

Based on the color variation, users can identify the robot's situation and users could take corrective measures.

Experimental results confirm that the robot can express its attention requirement to a user based on the state.

A user study has also been conducted to evaluate the performance improvement of the proposed method. 
According to the outcomes, the proposed method can remarkably improve the human-friendliness of a floor cleaning robot.
