Researchers have developed RoboTracer, a novel system that enhances robot trajectory tracking by leveraging 3D spatial perception and metric reasoning. Unlike previous methods that directly output joint torques or rely on 2D understanding, RoboTracer uses vision-language models to break down instructions into multi-step 3D trajectories with physical scales. This approach allows robots to better understand and execute complex tasks involving precise movements and obstacle avoidance, even with varying objects or distances. AI
