Fourier Transporter: Bi-Equivariant Robotic Manipulation in 3D

no code implementations22 Jan 2024 Haojie Huang, Owen Howell, Dian Wang, Xupeng Zhu, Robin Walters, Robert Platt

Many complex robotic manipulation tasks can be decomposed as a sequence of pick and place actions.

Can Euclidean Symmetry be Leveraged in Reinforcement Learning and Planning?

no code implementations17 Jul 2023 Linfeng Zhao, Owen Howell, Jung Yeon Park, Xupeng Zhu, Robin Walters, Lawson L. S. Wong

In robotic tasks, changes in reference frames typically do not influence the underlying physical properties of the system, which has been known as invariance of physical laws. These changes, which preserve distance, encompass isometric transformations such as translations, rotations, and reflections, collectively known as the Euclidean group.

On Robot Grasp Learning Using Equivariant Models

1 code implementation10 Jun 2023 Xupeng Zhu, Dian Wang, Guanang Su, Ondrej Biza, Robin Walters, Robert Platt

Real-world grasp detection is challenging due to the stochasticity in grasp dynamics and the noise in hardware.

Edge Grasp Network: A Graph-Based SE(3)-invariant Approach to Grasp Detection

no code implementations31 Oct 2022 Haojie Huang, Dian Wang, Xupeng Zhu, Robin Walters, Robert Platt

Given point cloud input, the problem of 6-DoF grasp pose detection is to identify a set of hand poses in SE(3) from which an object can be successfully grasped.

Equivariant Grasp learning In Real Time

no code implementations29 Sep 2021 Xupeng Zhu, Dian Wang, Ondrej Biza, Robert Platt

Visual grasp detection is a key problem in robotics where the agent must learn to model the grasp function, a mapping from an image of a scene onto a set of feasible grasp poses.
