Grasp model designed for rotation equivariance == greatly improved sample efficiency đ
We are introducing a new volumetric grasp model [1] that is equivariant to rotations around the vertical axis, drastically improving sample efficiency âĄ:
- Our model uses a tri-plane volumetric feature representation, i.e., our model uses the projection of 3D features onto the three XYZ canonical planes.
- We specifically designed our new model such that features on the horizontal plane are equivariant to 90° rotations đ, while the sum of features from the other two planes remains invariant to reflections âī¸ induced by the same transformations.
- A key enabler is a new deformable steerable convolution, which combines the adaptability of deformable convolutions with the rotational equivariance of steerable ones đšī¸.
