• Abstract summary: We present an approach for physical imitation from human videos for robot manipulation tasks. We design a perception module that learns to translate human videos to the robot domain followed by unsupervised keypoint detection. We evaluate the effectiveness of our approach on five robot manipulation tasks, including reaching, pushing, sliding, coffee making, and drawer closing.

• Abstract: We present an approach for physical imitation from human videos for robot manipulation tasks. The key idea of our method lies in explicitly exploiting the kinematics and motion information embedded in the video to learn structured representations that endow the robot with the ability to imagine how to perform manipulation tasks in its own context. To achieve this, we design a perception module that learns to translate human videos to the robot domain followed by unsupervised keypoint detection. The resulting keypoint-based representations provide semantically meaningful information that can be directly used for reward computing and policy learning. We evaluate the effectiveness of our approach on five robot manipulation tasks, including reaching, pushing, sliding, coffee making, and drawer closing. Detailed experimental evaluations demonstrate that our method performs favorably against previous approaches.

• Learning by Watching: A Review of Video-based Learning Approaches for Robot Manipulation [0.0]
  Recent works have explored learning manipulation skills by passively watching abundant videos sourced online. This survey reviews foundations such as video feature representation learning techniques, object affordance understanding, 3D hand/body modeling, and large-scale robot resources. We discuss how learning only from observing large-scale human videos can enhance generalization and sample efficiency for robotic manipulation.

  We show how passive human videos can serve as a rich source of data for learning such generalist robots. We learn a human plan predictor that, given a current image of a scene and a goal image, predicts the future hand and object configurations. We show that our learned system can perform over 16 manipulation skills that generalize to 40 objects.

  Humans inherently possess generalizable visual representations that empower them to efficiently explore and interact with the environments in manipulation tasks. We formalize this idea through the lens of human-oriented multi-task fine-tuning on top of pre-trained visual encoders. Our Task Fusion Decoder consistently improves the representation of three state-of-the-art visual encoders for downstream manipulation policy-learning.

  Humans are adept at learning new tasks by watching a few instructional videos. On the other hand, robots that learn new actions either require a lot of effort through trial and error, or use expert demonstrations that are challenging to obtain. In this paper, we explore a method that facilitates learning object manipulation skills directly from videos.
