摘要:

我们探讨了去中心化多智能体机器人场景中的安全控制挑战,其中智能体使用不确定的黑盒模型来预测其他智能体的轨迹。我们采用最近提出的共形决策理论,根据观测到的预测误差来调整基于控制障碍函数的安全约束的严格程度。我们利用这些约束来合成控制器,使其在存在预测误差的情况下平衡安全与任务完成的目标。我们提供了一个上界,该上界针对基于预测轨迹的安全约束与基于真实轨迹的约束之间差异的单调函数值,限定其在时间上的平均值。我们通过实验结果验证了理论,展示了控制器在Stanford Drone Dataset多智能体场景中导航机器人时的性能。

英文摘要:

We address the challenge of safe control in decentralized multi-agent robotic settings, where agents use uncertain black-box models to predict other agents' trajectories. We use the recently proposed conformal decision theory to adapt the restrictiveness of control barrier functions-based safety constraints based on observed prediction errors. We use these constraints to synthesize controllers that balance between the objectives of safety and task accomplishment, despite the prediction errors. We provide an upper bound on the average over time of the value of a monotonic function of the difference between the safety constraint based on the predicted trajectories and the constraint based on the ground truth ones. We validate our theory through experimental results showing the performance of our controllers when navigating a robot in the multi-agent scenes in the Stanford Drone Dataset.
