需要穿越受限和不确定环境的人形机器人需要感知、规划和控制的适当组合。本文提出了一个集成管道,允许机器人自主获取视觉信息,定义步骤位置,使用手和脚计算可行的多接触姿势,并生成运动计划以达到预期目标,即使经历不同的接触状态。通过基于无源的多触点控制器保证所需路径的执行。使用人形机器人 TORO 在不同场景下的模拟和实验中对该方法进行了评估。
Humanoid robots that need to traverse constrained and uncertain environments require a suitable combination of perception, planning and control. This paper presents an integrated pipeline that allows the robot to autonomously acquire visual information, define step locations, compute feasible multi-contact stances using hands and feet, and generate a motion plan to reach the desired goal even going through different contact states. The execution of the desired path is guaranteed through a passivity-based multi-contact controller. The approach is evaluated in simulations and experiments in different scenarios using the humanoid robot TORO.
