This ACT policy was trained for this dataset configuration and was not initialized from a published ACT base checkpoint. The visual backbone uses ImageNet-initialized ResNet-18 weights (ResNet18_Weights.IMAGENET1K_V1) as recorded in the training config.

Notes

This repo stores the final checkpoint that was uploaded from the cloud training workspace.
The checkpoint was trained with LeRobot tooling via lerobot-train.
For SO101 experiments in this workspace, the dataset source was created by Aswinkumar.
