About

Taichi Tajika is a pioneering researcher in the field of human-robot interaction, with a specific focus on haptic communication and social robotics. His work centers on developing robots that can physically and socially engage with humans through touch, a critical but often overlooked modality in robotics. Tajika’s major contribution is the creation of humanoid robots embedded with soft, tactile sensors that allow for safe and intuitive physical interaction. His seminal 2007 paper, "Haptic Communication Between Humans and Robots," (57 citations) introduced a method for detecting human positions and postures through haptic feedback, laying the groundwork for more responsive and aware robotic systems. He further advanced the field by integrating passive RFID tags and floor sensors to enable robots to identify and interact with multiple people simultaneously, as detailed in his 2008 work (13 citations). Notably, Tajika also addressed a key technical challenge—the interference of a robot’s own motion on its tactile sensors—by proposing a partially linear model to filter out this noise (2008, 4 citations). Through these innovations, Tajika has significantly advanced the development of robots capable of natural, touch-based communication, making them more suitable for daily life and social interaction.
