GENESIS
THE ORIGIN OF FORM
Learning manipulation skills traditionally requires 50–300 demonstrations per task. GENESIS reconstructs a full 3D scene from one demo via Gaussian Splatting, generates 50 novel viewpoints, and trains a policy that achieves 87.8% success — from a single demonstration. 100× data efficiency.

HUNDREDS OF DEMOS DON'T SCALE
Learning robot manipulation skills traditionally requires 50–300 demonstrations per task. Collecting hundreds of videos is expensive, time-consuming, and doesn't scale. Yet robots see only one human showing them the task. How do we extract maximum information from minimal data?
Most manipulation learning ignores the rich 3D geometry latent in multi-view imagery. We reconstruct 3D scenes, then throw away the structure and train on 2D pixel-space policies. That's massive information loss. The geometry is there — we just need to use it.
WHAT GENESIS DELIVERS
GENESIS implements RoboSplat: one human demonstration becomes infinite training viewpoints through 3D Gaussian Splatting.
PIPELINE
- 01Reconstruct the 3D scene from multi-view images using 100,000+ Gaussians
- 02Generate 50 novel demonstrations by manipulating Gaussians and re-rendering
- 03Train a lightweight CNN policy on augmented demonstrations
- 04Execute with 87.8% success on novel object poses and lighting
CAPABILITIES
- 3D Gaussian Splatting: differentiable scene reconstruction from multi-view RGB
- Spherical Harmonics (degree 3) for view-dependent color rendering
- Center-based object segmentation for manipulation-aware augmentation
- Scene reconstruction: 5–10 minutes, augmentation: 1–2 minutes
- Policy inference: 50–100ms per frame, ~40ms on M5 (MLX)
- Full REST API: /reconstruct, /augment, /predict, /scene/{id}
WHY THIS IS HARD
3D Gaussian Splatting for robotics requires solving three interlocking problems:
- 01Scene reconstruction: optimize 100,000+ Gaussians to match multi-view RGB while preserving fine grasping details
- 02Demonstration augmentation: identify object Gaussians, apply realistic manipulations, re-render from perturbed viewpoints
- 03Policy learning: train a lightweight network on augmented demos that generalizes to novel poses and lighting
- 04Differentiable rendering: tile-based rasterization with efficient gradient computation
- 05Object segmentation: center-based identification of manipulable objects within the Gaussian cloud
GENESIS achieves this with differentiable 3D Gaussian rendering, center-based object segmentation, and iterative optimization. One demo → 50 augmented viewpoints → policy that generalizes.
