四脚ロコ操作のためのふくらはぎ統合アーム
Calf-Integrated Arms for Bimanual Quadruped Loco-Manipulation
四脚ロボットの前脚ふくらはぎにマニピュレータを統合し、四脚を接地したまま両手での操作を可能にする設計を提案。視覚言語モデルによる長期的な自律操作も実証した。

原文アブストラクト
Most quadruped loco-manipulation designs trade manipulation capability against stance. A trunk-mounted arm sits high and usually carries a single arm; using the legs as manipulators lifts the manipulating leg off the ground; and even leg-mounted grippers reach two-handed tasks only by rearing onto the hind legs. This paper integrates a manipulator with a prismatic slider, two revolute joints, and a gripper into each front calf of a Unitree Go2. The two arms grasp objects at ground level and manipulate with both hands while all four feet stay planted, without rearing. With one arm carrying, the base stays free to walk. A vision-language model sequences skills from a predefined library at each skill boundary, conditioned on the head-camera image and task state, for long-horizon autonomy. In simulation, the design performs three bimanual tasks: a long-horizon cabinet task under autonomous skill selection, a cooperative two-handed lift, and an inter-arm handover.
