Design Challenge

Interaction Situation

This is the default behavior when the robot is turned on and currently not carrying out any other specific pattern.

Communication
Goal

„I am ready to interact with you and capable of initiating interaction by myself.”

Design Solution

Solution

Let the robot express that: It is ready to carry out an action using an open, upright posture (Ready). It directs its attention towards the user using a user-oriented positioning in the room, letting robot and user face each other (Attentive). Its operation mode is , setting the status light to permanently glowing (Operation mode on). Optionally, the robot could also express: That it is alive through idle movements of body, facial parts or on the floor (Lively).

Rationale

When maintaining an active status that can result in interaction between robot and user any time, the robot needs to communicate two aspects: being attentive towards the user to detect any attempt to initiate an interaction, and demonstrating its own readiness to signal to the user that they can expect it to start an (inter-)action itself. Detailed reasoning behind the design solutions for these two aspects can be found in the descriptions of the Atomic Patterns “Ready” and “Attentive”.
