Qwen-RobotNav技术报告:一种适用于代理式导航系统的可扩展导航模型
Qwen-RobotNav Technical Report: A Scalable Navigation Model Designed for an Agentic Navigation System
摘要
代理式导航系统需要一种基础导航模型,该模型的观测策略可以在推理过程中被外部重新配置。因为指令遵循、物体搜索、目标跟踪和自主驾驶这些功能都基于相同的感知-规划机制,但需要不同的策略来处理视觉信息。我们提出了Qwen-RobotNav这一可扩展的导航模型,它通过具有两个互补维度的参数化接口来解决这一问题:一种能够选择导航行为的多种任务模式,以及可以控制的观测参数(如令牌预算、每个摄像机的权重),这些参数决定了视觉信息的编码方式。通过在所有参数上进行随机化训练,Qwen-RobotNav能够适应任何在推理过程中所需的配置方式,而无需对模型结构进行任何修改。我们在1560万个样本上训练了Qwen-RobotNav;与视觉语言数据的联合训练避免了仅使用轨迹数据进行训练时出现的反应式动作序列问题。参数化接口还使得Qwen-RobotNav成为代理式系统的理想构建模块:对于长距离场景,高层规划器可以将目标分解为子任务,并在游戏过程中动态切换Qwen-RobotNav的任务模式和策略,从而实现复杂的行为表现。大量实验表明,Qwen-RobotNav在各种导航基准测试中取得了新的最佳成绩。当参数从20亿增加到80亿时,模型仍然表现出良好的扩展性,联合多任务训练则形成了一种跨任务类别通用的空间规划机制,同时还能在多种环境中对真实机器人进行有效的零样本泛化。
English Abstract
Agentic navigation systems require a base navigation model whose observation strategy can be externally reconfigured at inference time, because instruction following, object search, target tracking, and autonomous driving share the same perception-planning backbone yet demand fundamentally different strategies for consuming the visual stream. We present Qwen-RobotNav, a scalable navigation model built on Qwen-RobotNav that addresses it through a parameterised interface with two complementary dimensions: multiple task modes that select the navigation behaviour, and controllable observation parameters (e.g., token budget, per-camera weights) that govern how visual history is encoded. With training-time randomization over all parameters, Qwen-RobotNav is robust to any inference-time configuration requiring zero architectural modification to the Qwen-RobotNav backbone. We train Qwen-RobotNav on 15.6M samples; co-training with vision-language data prevents the collapse into reactive action-sequence mappers observed in trajectory-only training. The parameterised interface also makes Qwen-RobotNav a natural building block for agentic systems: for long-horizon scenarios, an upper-level planner decomposes goals into sub-tasks and dynamically switches Qwen-RobotNav's task mode and context strategy mid-episode, composing complex behaviours from repeated calls to the same model. Extensive experiments show that Qwen-RobotNav sets new state-of-the-art results across major navigation benchmarks. The model exhibits favourable scaling from 2B to 8B parameters, with joint multi-task training developing a shared spatial-planning substrate that transfers across task families, and demonstrates strong zero-shot generalisation to real-world robots across diverse environments.
