The Short Version
Switch between Solo, Mobile, and Stationary setups using the new YAML-based configuration system.
Edit predefined setups in the configs/robot directory to extend Solo, Mobile, and Stationary robots.
Update camera serial numbers via the aloha_solo.yaml file for your custom setup.
Specify robot names, models, and orientations to define custom configurations.
Define tasks, dataset directories, and episode lengths in tasks_config.yaml for imitation learning.
Run teleop.py for teleoperation, record_episodes.py or auto_record.sh to collect data, and replay_episodes.py to evaluate.

The ALOHA 2.0 package brings a transformative update to the world of robotics, introducing modular configurations and enhanced flexibility for robotic workflows. Refactoring the ALOHA pipeline means one cohesive framework now supports three setups — Solo, Mobile, and Stationary — all managed through a YAML-based configuration system. Trossen Robotics designed the refactor to streamline operations, so you can switch between robot setups without rewriting your pipeline.
What’s New in ALOHA 2.0?
Unified Modular Configurations
The new YAML-based configuration system allows users to switch seamlessly between robot setups. Whether you’re working on a single-arm ALOHA Solo or a multi-camera, multi-arm Mobile setup, all configurations can be defined and managed effortlessly in YAML files.
Customizable Robot Setups
The refactoring enables users to define custom configurations for their unique project needs. From specifying camera positions to configuring leader and follower arms, ALOHA 2.0 adapts to your requirements with precision.
Enhanced Workflow Efficiency
The refactored scripts are now modular, making them reusable across different setups. Scripts for teleoperation, recording episodes, and replaying tasks have been optimized for flexibility and ease of use.
What are the key features of ALOHA 2.0?
Robot Configurations
The `configs/robot` directory contains predefined setups for the 3 robot variants — Solo, Mobile, and Stationary. Users can extend these configurations by simply editing the YAML files. For example:
Update camera serial numbers via the `aloha_solo.yaml` file.
Specify robot names, models, and orientations for custom setups.
Task Management
The `tasks_config.yaml` file allows users to define tasks with parameters like task names, dataset directories, and episode lengths. This simplifies data collection for imitation learning.
Modular Scripts
Use `teleop.py` for teleoperation with optional gravity compensation.
Run `record_episodes.py` to collect data, or `auto_record.sh` for batch recordings.
Replay episodes using `replay_episodes.py` to visualize and evaluate performance.
Why does refactoring the ALOHA pipeline matter?
This refactoring effort ensures that the ALOHA package is future-proof, adaptable to diverse research needs, and ready for the growing demands of robotics and machine learning.
By unifying configurations and optimizing scripts, ALOHA 2.0 provides a robust foundation for researchers, developers, and educators alike.
