• Abstract summary: We present a large-scale automated data generation system that synthesizes trajectories from human demonstrations for humanoid robots with dexterous hands. We generate 21K demos across these tasks from just 60 source human demos. We also present a real-to-sim-to-real pipeline and deploy it on a real-world humanoid can sorting task.

• Abstract: Imitation learning from human demonstrations is an effective means to teach robots manipulation skills. But data acquisition is a major bottleneck in applying this paradigm more broadly, due to the amount of cost and human effort involved. There has been significant interest in imitation learning for bimanual dexterous robots, like humanoids. Unfortunately, data collection is even more challenging here due to the challenges of simultaneously controlling multiple arms and multi-fingered hands. Automated data generation in simulation is a compelling, scalable alternative to fuel this need for data. To this end, we introduce DexMimicGen, a large-scale automated data generation system that synthesizes trajectories from a handful of human demonstrations for humanoid robots with dexterous hands. We present a collection of simulation environments in the setting of bimanual dexterous manipulation, spanning a range of manipulation behaviors and different requirements for coordination among the two arms. We generate 21K demos across these tasks from just 60 source human demos and study the effect of several data generation and policy learning decisions on agent performance. Finally, we present a real-to-sim-to-real pipeline and deploy it on a real-world humanoid can sorting task. Videos and more are at https://dexmimicgen.github.io/

  Human demonstrations as prompts are a powerful way to program robots to do long-horizon manipulation tasks. translating these demonstrations into robot-executable actions presents significant challenges due to execution mismatches in movement styles and physical capabilities. We propose RHyME, a novel framework that automatically aligns human and robot task executions using optimal transport costs.

  Learning predictive models from interaction with the world allows an agent, such as a robot, to learn about how the world works.

We propose a method to augment the training set with observational data of other agents, such as humans.
