LeRobot SO101 ACT task3-unknown_bs32_s60000

Summary

This repository contains the final checkpoint for a ACT policy trained on aswinkumar99/task3-unknown for SO101 sponge pick-and-place experiments.

Dataset meaning: Task 3: Single Sponge - With Distractors (random-locations / unknown).

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.
