一种结合语言引导的神经网络模型预测控制框架，用于关节履带机器人的自主穿越
ASTRIL-MPC: Autonomous Traversal Framework of Articulated Tracked Robots with Language-Guided Neural-Kinematic MPC
这个研究挺有意思，用语言模型来动态调整机器人的控制参数，让它在复杂地形上更聪明地移动，效果比传统方法好很多。
在楼梯和复杂建筑内部等结构化但接触丰富的环境中，关节履带机器人（ATRs）的可靠自主性面临挑战。我们提出 ASTRIL-MPC 框架，它使用一个学习到的运动学模型预测短期任务状态增量，通过多目标成本和严格可行性约束的 NMPC 进行规划，并利用大型语言模型（LLM）通过安全检查接口提出有界权重更新。在三个穿越任务和一个多高度泛化设置中，该框架将总穿越质量评分提高了71%，并消除了下降过程中的可测量碰撞影响。
ASTRIL-MPC: Autonomous Traversal Framework of Articulated Tracked Robots with Language-Guided Neural-Kinematic MPC
In urban search and rescue, articulated tracked robots (ATRs) must traverse structured but contact-rich environments such as stairwells and cluttered building interiors. Reliable autonomy remains challenging because robot-terrain interaction (RTI) is hybrid and discontinuous, and effective flipper-track coordination is difficult to model analytically. We present ASTRIL-MPC, a language-guided neural kinematics model predictive control (MPC) framework for autonomous traversal. A learned kinematics model predicts short-horizon task-state increments from a height sequence and recent trajectories; NMPC plans with multi-objective costs and strict feasibility constraints; and a large language model (LLM) proposes bounded updates to selected weights and bounds through a safety-checked interface with range clipping, rate limiting, and consistency checks. The compiled predictor enables a full control cycle within 100 ms. Across three traversal tasks and a multi-height generalization setting, ASTRIL-MPC improves an aggregate traversal-quality score by up to 71% over a non-adaptive NMPC and by 67% over a PPO baseline, while eliminating measurable collision impacts during descent. These results indicate that combining learned kinematics, optimization-based planning, and language-guided retuning yields data-efficient and robust autonomy for articulated tracked robots.
