ProDapt

Proprioceptive Adaptation for Autonomous Manipulation Tasks

References

The initial work in this repo evolved from cleaning up sections of code from: https://github.com/real-stanford/diffusion_policy.

Installation

This repository can be used either natively or using Docker. Regardless, we assume the directory is cloned in your home directory.

Direct Installation

This repository has been tested using ROS2 Foxy installed on Ubuntu 20.04, using Python 3.8, with relevant packages installed via:

./scripts/install.bash

However, everything should also work for ROS2 Humble on Ubuntu 22.04 and Python 3.10.

Docker

The docker image for the project can be built using

cd ~/prodapt
docker build -t prodapt:latest -f ./docker/prodapt/Dockerfile .

and then run via

cd ~/prodapt/docker
docker compose up prodapt

This container is for Ubuntu 22.04 to run ROS2 Humble. It has all the necessary packages and Python modules installed. Additionally, it loads the prodapt repository as a volume so work can be done directly from the Docker container.

Open the container using VSCode's Dev Containers extension, using the command Dev Containers: Attach to Running Container. Then, both running and developing this repository can be done from inside the container.

Note: If you wish to use the Spacemouse (see spacemouse.md) to control the UR10e robot (either in simulation or real life), you will need to run docker from a Linux computer. Before building the docker container for the first time run:

sudo apt-get install spacenavd
service spacenavd restart

Running Push-T Example

Download the trained weights for the push-T example by running

./scripts/download_push_t_weights.bash

which should create the folder prodapt/checkpoints and add the file pusht_state_100ep.ckpt. Then, run the experiment by running

python3 -m prodapt.main --config-name=push_t.yaml mode=inference inference.checkpoint_path=./checkpoints/pusht_state_100ep.ckpt

which should run an evaluation that has a final score of approximately 0.95. A video of the experiment can be found in the prodapt/output folder, in the latest experiment.

Training Push-T Example

Download the training data for the push-T example by running

./scripts/download_push_t_data.bash

which should create the folder prodapt/data/push_t_data.zarr folder and populate it with data. Then, run the training by running

python3 -m prodapt.main --config-name=push_t.yaml mode=train

This will begin training (100 epochs), which should take ~10min. Then, evaluate the policy by running

python3 -m prodapt.main --config-name=push_t.yaml mode=inference

which could return a score of approximately 0.95.

Debugging

A list of common problems that may be encountered when first setting up the repo

Error:

AssertionError: Cannot find installation of real FFmpeg (which comes with ffprobe)

Problem: FFmpeg has likely not been installed or updated on your host.

Solution:

sudo apt-get install ffmpeg
