„The Robodog Project: Bao Meets Pluto“ examined how domestic dogs respond to the Unitree Go2 quadruped robot – nicknamed Bao by project initiator Prof. Dr. Oliver Bendel – and how their owners perceive such robots in shared public spaces. The project began in late March 2025 and was completed in early August 2025. The study addressed three questions: (1) How do dogs behaviorally respond to a quadruped robot across six conditions: stationary, walking, and jumping without an additional dog head, and stationary, walking, and jumping with an additional 3D-printed dog head? (2) What are owners‘ expectations and concerns? (3) What regulatory frameworks could support safe integration? Twelve dogs were observed in six structured interaction phases; their behavior was video-coded using BORIS. Another dog participated in a preliminary test but not in the actual study. Pre-exposure interviews with eight owners, as well as an expert interview with a biologist and dog trainer, provided additional insights. Led by Selina Rohr, the study found most dogs were cautious but not aggressive. Curiosity increased during robot movement, while visual modifications had little impact. However, a 3D-printed dog head seemed to interest the dogs quite a bit when the robot was in standing mode. Dogs often sought guidance from their owners, underlining the role of human mediation. Owners were cautiously open but emphasized concerns around safety, unpredictability, and liability. The findings support drone-like regulation for robot use in public spaces.
