Sapling & the Travelling Forest: A table-top mobile robot platform for child-robot games

Abstract

Mobile robots can provide unique and engaging experiences for child-robot gameplay, but are often overlooked due to challenges of setup, navigation, and space limitations. To combat these challenges, we designed "Sapling and the Travelling Forest,"a small mobile robot that uses a table-top game platform to play games with children. The system was designed as a low-cost and travel friendly alternative to larger mobile robot setups, and can be used in any location with a power outlet. The robot, "Sapling,"is an interactive agent that moves through the "Travelling Forest"platform which frames the system and contains the robot to the forest play area. The system currently offers three games focused on collaborative, spatial play. Radio frequency identification (RFID) enabled games allow Sapling to meaningfully interact with both the game elements and a child. In this paper, we present the technical design of the robot and its small, table-top platform, as well as the game design process for the three board games. The presented system is a convenient way to conduct single or multi-session child-robot interaction studies with mobile robots.
