Does Height Affect the Strictness of Robot Assisted Teacher?

For humans, a taller height is an advantage in expressing one's dominant strictness to others. To this point, robotic telepresence has preferred low-height robotic platforms for reasons such as operational stability, user convenience and psychological comfort. We examined whether the height of the robot had an effect on an instructor connected to a telepresence robot in robot-assisted learning with regard to controlling a large number of students. The experiment showed that the use of a taller robot, compared to a shorter robot, did not make a meaningful difference in the instructors' authority being accepted by the students. Though, students felt a shorter robot friendly than a life-size taller robot.
