Sumo: 動的かつ汎用的な全身ロコ操作
Sumo: Dynamic and Generalizable Whole-Body Loco-Manipulation
事前学習した全身制御ポリシーをテスト時にサンプルベースのプランナーで操縦することで、脚式ロボットが大型・重量物を動的に操作できるようにするsim-to-real手法を提案。実機のSpotでタイヤの直立やバリアの引きずり等を実証し、シミュレーションで人型ロボットへの汎用性も示した。

This paper presents a sim-to-real approach that enables legged robots to dynamically manipulate large and heavy objects with whole-body dexterity. Our key insight is that by performing test-time steering of a pre-trained whole-body control policy with a sample-based planner, we can enable these robots to solve a variety of dynamic loco-manipulation tasks. Interestingly, we find our method generalizes to a diverse set of objects and tasks with no additional tuning or training, and can be further enhanced by flexibly adjusting the cost function at test time. We demonstrate the capabilities of our approach through a variety of challenging loco-manipulation tasks on a Spot quadruped robot in the real world, including uprighting a tire heavier than the robot's nominal lifting capacity and dragging a crowd-control barrier larger and taller than the robot itself. Additionally, we show that the same approach can be generalized to humanoid loco-manipulation tasks, such as opening a door and pushing a table, in simulation.
