Multi-Model 3D Registration: Finding Multiple Moving Objects in Cluttered Point Clouds

no code implementations16 Feb 2024 David Jin, Sushrut Karmalkar, Harry Zhang, Luca Carlone

We investigate a variation of the 3D registration problem, named multi-model 3D registration.

POLAR3D: Augmenting NASA's POLAR Dataset for Data-Driven Lunar Perception and Rover Simulation

1 code implementation21 Sep 2023 Bo-Hsun Chen, Peter Negrut, Thomas Liang, Nevindu Batagoda, Harry Zhang, Dan Negrut

POLAR3D is the set of digital assets comprising of rock/shadow labels and obj files associated with the digital twins of lunar terrain scenarios.

APLA: Additional Perturbation for Latent Noise with Adversarial Training Enables Consistency

no code implementations24 Aug 2023 Yupu Yao, ShangQi Deng, ZiHan Cao, Harry Zhang, Liang-Jian Deng

One underlying cause is that traditional diffusion models approximate Gaussian noise distribution by utilizing predictive noise, without fully accounting for the impact of inherent information within the input itself.

FlowBot3D: Learning 3D Articulation Flow to Manipulate Articulated Objects

no code implementations9 May 2022 Ben Eisner, Harry Zhang, David Held

We propose a vision-based system that learns to predict the potential motions of the parts of a variety of articulated objects to guide downstream motion planning of the system to articulate the objects.

Orienting Novel 3D Objects Using Self-Supervised Learning of Rotation Transforms

no code implementations29 May 2021 Shivin Devgon, Jeffrey Ichnowski, Ashwin Balakrishna, Harry Zhang, Ken Goldberg

We formulate a self-supervised objective for this problem and train a deep neural network to estimate the 3D rotation as parameterized by a quaternion, between these current and desired depth images.

Robots of the Lost Arc: Self-Supervised Learning to Dynamically Manipulate Fixed-Endpoint Cables

no code implementations10 Nov 2020 Harry Zhang, Jeffrey Ichnowski, Daniel Seita, Jonathan Wang, Huang Huang, Ken Goldberg

The framework finds a 3D apex point for the robot arm, which, together with a task-specific trajectory function, defines an arcing motion that dynamically manipulates the cable to perform tasks with varying obstacle and target locations.
