Core Viewpoint - Goal-Oriented Navigation empowers robots to autonomously complete navigation tasks based on goal descriptions, marking a significant shift from traditional visual language navigation systems [2][3]. Group 1: Technology Overview - Embodied navigation is a core area of embodied intelligence, relying on three technical pillars: language understanding, environmental perception, and path planning [2]. - Goal-Oriented Navigation allows robots to explore unfamiliar 3D environments and plan paths using only goal descriptions such as coordinates, images, or natural language [2]. - The technology has been industrialized across various verticals, including delivery, healthcare, hospitality, and industrial logistics, showcasing its adaptability and effectiveness [3]. Group 2: Technological Evolution - The evolution of Goal-Oriented Navigation can be categorized into three generations: 1. **First Generation**: End-to-end methods focusing on reinforcement learning and imitation learning, achieving breakthroughs in Point Navigation and closed-set image navigation tasks [5]. 2. **Second Generation**: Modular methods that explicitly construct semantic maps, breaking tasks into exploration and goal localization phases, showing significant advantages in zero-shot object navigation [5]. 3. **Third Generation**: Integration of large language models (LLMs) and visual language models (VLMs) to enhance knowledge reasoning and open-vocabulary target matching accuracy [7]. Group 3: Challenges and Learning Path - The complexity of embodied navigation, particularly Goal-Oriented Navigation, requires knowledge from multiple fields, including natural language processing, computer vision, and reinforcement learning [9]. - The fragmented nature of knowledge and the abundance of literature make it challenging for newcomers to extract frameworks and understand development trends [9]. - A new course has been developed to address these challenges, focusing on practical applications and theoretical foundations to facilitate learning [10][11][12]. Group 4: Course Structure - The course is structured to cover various aspects of Goal-Oriented Navigation, including: 1. **Semantic Navigation Framework**: Establishing theoretical foundations and technical lineage [14]. 2. **Habitat Simulation Ecosystem**: Analyzing the technical architecture of the Habitat platform [15]. 3. **End-to-End Navigation Methodology**: Teaching core algorithms and performance differences [16]. 4. **Modular Navigation Architecture**: Focusing on semantic map construction and task decomposition strategies [17]. 5. **LLM/VLM Driven Navigation Systems**: Exploring integration paradigms and algorithm design [18]. Group 5: Practical Application - The course includes a major project focusing on the replication of VLFM algorithms and real-world deployment, allowing participants to engage in hands-on learning [18][22].
