RDT-1B is a 1.2B-parameter diffusion-based foundation model for bimanual robotic manipulation, from Tsinghua's TSAIL group. Pre-trained on 1M+ multi-robot episodes, it predicts the next 64 robot actions from a language instruction plus 3-view RGB observations. Published at ICLR 2025. Both code and weights are MIT-licensed — the most permissive license among the major Chinese embodied models, which makes it a common research baseline. A newer RDT2 line is also published.
Bimanual manipulation research; permissive-license baseline for fine-tuning on custom robot data.
