Faster PI0-FAST model inference with a few frequency domain tricks
Objective: Faster PI0-FAST robot VLA (Vision-Language-Action) model inference time; A DCT (discrete cosine transform) early stopping trick implementation for FAST (Frequency-Space Action Sequence Tokenization). The idea is to decode only the first few DCT coefficients from the PaLi-Gemma VLM rather than waiting for a full action chunk inference to complete. This can cut down inference to action time by roughly half since around the first 3-4 frequency harmonics of the DCT are typically enough for a coarse action sequence reconstruction.
YuMi IRB14000 Bimanual Robot Realtime Control Package
Open source software package to control the ABB YuMi IRB14000 bimanual robot in realtime (240Hz) through control interfaces including: interactive websocket GUI, Meta Quest VR Controllers, and autonomous Diffusion Policy (shown), PI0-FAST and NVIDIA-GR00T VLA models.
