Researchers have developed a novel method for robots to dynamically avoid obstacles in unstructured outdoor environments without requiring extensive robot-specific training data. The approach utilizes a pretrained vision model, UniDepth, for depth estimation and extends the SuperPoint and SuperGlue feature correspondence pipeline to track keypoints in 3D. By computing time-to-collision (TTC) for these keypoints, the system can select appropriate motion primitives to steer the robot away from potential collisions. This method demonstrated high data efficiency, requiring only minimal data for hyperparameter tuning, and achieved significant success in detecting and reacting to various physical obstacles. AI
