Self-supervised 6-DoF Robot Grasping by Demonstration via Augmented Reality Teleoperation System

no code implementations3 Apr 2024 Xiwen Dengxiong, Xueting Wang, Shi Bai, Yunbo Zhang

Most existing 6-DoF robot grasping solutions depend on strong supervision on grasp pose to ensure satisfactory performance, which could be laborious and impractical when the robot works in some restricted area.

Learning to Transfer In-Hand Manipulations Using a Greedy Shape Curriculum

no code implementations14 Mar 2023 Yunbo Zhang, Alexander Clegg, Sehoon Ha, Greg Turk, Yuting Ye

In-hand object manipulation is challenging to simulate due to complex contact dynamics, non-repetitive finger gaits, and the need to indirectly control unactuated objects.

Learning to Manipulate Amorphous Materials

no code implementations3 Mar 2021 Yunbo Zhang, Wenhao Yu, C. Karen Liu, Charles C. Kemp, Greg Turk

We produce a final animation by using inverse kinematics to guide a character's arm and hand to match the motion of the manipulation tool such as a knife or a frying pan.

Learning Novel Policies For Tasks

no code implementations13 May 2019 Yunbo Zhang, Wenhao Yu, Greg Turk

Our method does this by creating a second reward function that recognizes previously seen state sequences and rewards those by novelty, which is measured using autoencoders that have been trained on state sequences from previously discovered policies.
