## 核心内容

针对共享空间中机器人跟随目标易受干扰物影响的问题，研究团队提出VLX-Go视觉语言航点策略。该方法采用多阶段训练范式，在19532个Oracle回合数据上完成从视觉语言对齐、多模态推理到跟踪专精的渐进式学习。实验显示，其干扰环境跟踪成功率达55.80%，较前代OmTrackVLA模型的41.54%显著提升，确立了分阶段多模态学习在复杂跟随任务中的有效性。

系统架构融合冻结视觉编码器、多尺度时序上下文与Transformer骨干网络，输出以机器人为中心的航点预测。进一步引入基于过滤Oracle标签的在策略优化机制，利用策略实际访问状态进行微调，使干扰跟踪成功率再增2.42个百分点至58.22%，同时碰撞率下降1.99个百分点。该方案在干扰及歧义场景下均取得对比方法中最优性能，项目代码已在GitHub开源。

## 英文摘要 (Abstract)

Embodied visual tracking requires a robot to identify a designated target from visual observations and control its own motion to follow that target through an environment. Following an isolated person is a comparatively simple demonstration of embodied visual tracking, but following the intended person among distractors remains challenging. Existing methods exhibit a substantial drop in success from single-target to distractor tracking, motivating a focus on the shared spaces that person-following robots must navigate. We present VLX-GO, a vision-language waypoint policy built around the hypothesis that visual and language representations should be aligned before tracking-specific motion is learned. The policy combines complementary frozen visual encoders, multiscale temporal context, a transformer backbone, and a lightweight head for robot-centric waypoint prediction. Its training progresses through vision--language alignment, multimodal reasoning mid-training, and tracking specialization on 19,532 oracle episodes. Compared with 41.54% distractor-tracking success for our earlier OmTrackVLA model, the complete multi-stage recipe achieves 55.80%. We then explore on-policy refinement using filtered oracle labels for states visited by the policy. This preliminary study adds 2.42 percentage points of distractor-tracking success, reaching 58.22%, while reducing collision rate by 1.99 pts. The final policy records the highest distractor- and ambiguous-tracking success rates among the compared methods. These results support staged multimodal learning as a promising direction for tracking among distractors and motivate further study of on-policy refinement for person following in shared spaces.
