Implementing motion imitation methods involves lots of nuisances. Not many codebases get all the details right. So, we're excited to release MimicKit! github.com/xbpeng/MimicKit A framework with high quality implementations of our methods: DeepMimic, AMP, ASE, ADD, and more to come!

Getting SDS to work for motion imitation has been tricky. But we finally got it to work! With SMP, you can train a diffusion prior on a dataset, freeze it, and reuse it over and over again as a style reward to train new controllers. Try it out: github.com/xbpeng/MimicKit

Can we build a standalone, modular, and reusable naturalness reward for training motor controllers? #SMP is a step toward that vision. Once SMP has been trained on a motion dataset, the priors can be reused to train new controllers to perform diverse tasks while adhering to the

It's always challenging to find the right motion data for training humanoid controllers. With Kimodo you can now generate exactly the data you want through an intuitive and expressive interface. Like having a mocap actor on-demand!

A nice little quality-of-life update, MimicKit now supports video logging. You can monitor the agent's behaviors during training on WandB and Tensorboard: github.com/xbpeng/MimicKi… We also added an implementation of Lipschitz-Constrained Policies for training smooth controllers.
