Add RoboTracer

[leeibo]

Thanks for maintaining this awesome list!

I would like to add the paper RoboTracer: Mastering Spatial Trace with Reasoning in Vision-Language Models for Robotics to the list, following the existing format.

Summary:

• We propose RoboTracer, a 3D-aware vision-language model that accepts arbitrary geometric inputs and leverages scale supervision with metric-sensitive rewards for spatial tracing.
• We introduce TraceSpatial, a well-annotated dataset for spatial tracing with reasoning, and TraceSpatial-Bench, a benchmark addressing the lack of evaluation protocols for this task.
• Extensive experiments show that RoboTracer outperforms strong baselines in spatial measurement, referring, tracing, and enables efficient control of diverse real-world robots.
