Abstract: Robotic perception technology is a core competency that undergraduate robotics engineering students must master for robot design, development, integration, and maintenance, significantly impacting their professional development. This study addresses existing pedagogical limitations by proposing a blended online-offline teaching model guided by the Outcome-Based Education (OBE) framework. The reform focuses on enhancing self-directed learning capabilities and educational outcomes through the following measures: Curriculum Optimization: Integrating and refining course content to align with industrial demands; Digital Resource Development: Building a comprehensive online learning platform with modular materials; Hybrid Instructional Design: Implementing a structured "pre-class, in-class, post-class" workflow, incorporating flipped classrooms and task-driven experimental projects; Holistic Education: Embedding ideological and political education throughout the teaching process to synergize theoretical and practical learning. After one academic cycle of implementation, student engagement and academic performance demonstrated measurable improvements. This study offers actionable insights for innovating robotics engineering education under the Emerging Engineering Education (3E) initiative.
