AI中文摘要:
我们展示了一种跳跃机器人,它通过单条长腿和直驱传动实现高(7.6米)且快(190毫秒触地时间)的跳跃,无需弹性储能。在281克重量下,它实现了电驱动无弹簧系统迄今报告的最高跳跃。该腿采用一种新型织物包裹传动,提供可变机械优势,使小型电机在行程中保持接近峰值功率输出,同时支撑细长轻质腿以抵抗屈曲。腿顶部的平衡模块使用小型螺旋桨控制腿在地面和空中的姿态,其中长腿为控制扭矩提供了大臂力臂。该机器人经过户外垂直跳跃、地面和飞行中的姿态控制以及倾斜跳跃验证。
英文摘要:
We demonstrate a jumping robot that reaches high (7.6 m) and fast (190 ms stance time) jumps from a single long leg driven by a direct-drive transmission, without elastic energy storage. At 281 g, it achieves the highest jump yet reported for an electrically actuated, spring-free system. The leg uses a new fabric-wrap transmission that provides a variable mechanical advantage, keeping a small electric motor near its peak power output through the stroke while bracing the long, lightweight leg against buckling. A balancing module at the top of the leg uses small propellers to control the leg's orientation on the ground and in the air, where the long leg provides a large moment arm for the control torques. The robot is validated outdoors with vertical jumps, attitude control on the ground and in flight, and tilted jumps.
