摘要:

我们研究机器人助理穿衣,可以预测的人谁是被帮助的运动。为此,我们使用强化学习来创建辅助穿衣过程中的人类行为模型。为了探索这种交互,我们假设机器人向一个人展示了一件敞开的医院长袍袖子,而这个人将他们的手臂移动到袖子中。模拟人的行为的控制器被给予袖子末端的位置和关于人的手与长袍的织物之间的接触的信息。我们模拟这个系统与人体躯干模型,具有现实的关节范围,一个简单的机器人抓手,和基于物理的衣服模型的长袍。通过强化学习(特别是TRPO算法),系统创建了一个能够将手臂放入袖子中的人类行为模型。我们的目标是模拟人类能够做什么,而不是他们通常做什么。我们展示了三种机器人辅助穿衣策略的成功训练的人类行为:1)机器人夹持器保持套筒不动,2)夹持器将套筒从前面线性地朝向人移动,3)夹持器从侧面线性地移动套筒。

英文摘要:

We investigate robotic assistants for dressing that can anticipate the motion of the person who is being helped. To this end, we use reinforcement learning to create models of human behavior during assistance with dressing. To explore this kind of interaction, we assume that the robot presents an open sleeve of a hospital gown to a person, and that the person moves their arm into the sleeve. The controller that models the person's behavior is given the position of the end of the sleeve and information about contact between the person's hand and the fabric of the gown. We simulate this system with a human torso model that has realistic joint ranges, a simple robot gripper, and a physics-based cloth model for the gown. Through reinforcement learning (specifically the TRPO algorithm) the system creates a model of human behavior that is capable of placing the arm into the sleeve. We aim to model what humans are capable of doing, rather than what they typically do. We demonstrate successfully trained human behaviors for three robot-assisted dressing strategies: 1) the robot gripper holds the sleeve motionless, 2) the gripper moves the sleeve linearly towards the person from the front, and 3) the gripper moves the sleeve linearly from the side.
