動的六脚ロボットBruceの設計と開発
Bruce -- Design and Development of a Dynamic Hexapod Robot
CSIROが開発した動的六脚ロボットBruceは、約80%の3Dプリント部品と直列弾性アクチュエータを用い、1年未満で設計から実環境展開までを実現した。芝生・岩・瓦礫などの不整地を0.3m/s、平地を最大0.5m/sで移動できる。

This paper introduces Bruce, the CSIRO Dynamic Hexapod Robot capable of autonomous, dynamic locomotion over difficult terrain. This robot is built around Apptronik linear series elastic actuators, and went from design to deployment in under a year by using approximately 80\% 3D printed structural (joints and link) parts. The robot has so far demonstrated rough terrain traversal over grass, rocks and rubble at 0.3m/s, and flat-ground speeds up to 0.5m/s. This was achieved with a simple controller, inspired by RHex, with a central pattern generator, task-frame impedance control for individual legs and no foot contact detection. The robot is designed to move at up to 1.0m/s on flat ground with appropriate control, and was deployed into the the DARPA SubT Challenge Tunnel circuit event in August 2019.
