"Ranger" is a robotic box designed to motivate young children to tidy up the toys in their rom. It explores the idea of integrating robotics into daily life objects, such as a wooden box. The box shows light and sound when toys are put inside or removed. We carried out a series of field experiments (Wizard-of-Oz) with 14 families to evaluate the first prototype of Ranger. The robot was operated showing two different behaviors: an active or a passive one. We found that the robot's behavior had an impact on how children interacted with it. The poster also describes children's and parent's evaluation of the robot and how the design of Ranger could be improved.
