摘要:
本文提出了一种新颖的双足运动控制器,该控制器利用带噪声的外部感知来穿越多种多样的地形。基于四足运动中基于注意力的信念编码的前沿进展,我们的工作将这些方法扩展到双足领域,从而在传感器输入存在噪声的情况下,仍能对前方地形形成稳健可靠的内部信念。此外,我们提出了一种奖励函数,使控制器能够成功穿越不规则地形。我们将我们的方法与本体感知基线进行了比较,结果表明我们的方法能够穿越多种多样的地形,并在鲁棒性、速度和效率方面大幅优于当前最先进的方法。
英文摘要:
In this paper we propose a novel bipedal locomotion controller that uses noisy exteroception to traverse a wide variety of terrains. Building on the cutting-edge advancements in attention based belief encoding for quadrupedal locomotion, our work extends these methods to the bipedal domain, resulting in a robust and reliable internal belief of the terrain ahead despite noisy sensor inputs. Additionally, we present a reward function that allows the controller to successfully traverse irregular terrain. We compare our method with a proprioceptive baseline and show that our method is able to traverse a wide variety of terrains and greatly outperforms the state-of-the-art in terms of robustness, speed and efficiency.
