ManiCM addresses the critical latency bottleneck in diffusion-based robotic manipulation by enforcing consistency constraints, enabling real-time one-step inference from point cloud inputs. This approach accelerates action generation tenfold compared to standard multi-step denoising methods while preserving high success rates on complex tasks like those found in Adroit and Metaworld benchmarks. The technique represents a significant advancement for deploying generative AI models in low-latency robotic control applications where traditional diffusion processes are too slow.
ManiCM: Real-time 3D Diffusion Policy via Consistency Model for Robotic Manipulation
arXiv:2406.01586v4 Announce Type: replace Abstract: Diffusion models have been verified to be effective in generating complex distributions from natural images to motion trajectories. Recent diffusion-based methods show impressive performance in 3D robotic manipulation tasks, whereas they suffer from severe runtime inefficiency due to multiple denoising steps, especially with high-dimensional observations. To this end, we propose a real-time robotic manipulation model named ManiCM that imposes the consistency constraint to the diffusion process, so that the model can generate robot actions in only one-step inference. Specifically, we formulate a consistent diffusion process in the robot action space conditioned on the point cloud input, where the original action is required to be directly denoised from any point along the ODE trajectory. To model this process, we design a consistency distillation technique to predict the action sample directly instead of predicting the noise within the vision community for fast convergence in the low-dimensional action manifold. We evaluate ManiCM on 31 robotic manipulation tasks from Adroit and Metaworld, and the results demonstrate that our approach accelerates the state-of-the-art method by 10 times in average inference speed while maintaining competitive average success rate.
