Stanford University, May 2020 - October 2020
Supervisor: Dr. Shenli Yuan, Prof. J. Kenneth Salisbury

The ability to perform in-hand manipulation still remains an unsolved problem; Having this capability would allow robots to perform sophisticated tasks requiring repositioning and reorienting of grasped objects. Based on the work of Roller Grasper V1 before, this project aims to achieve dexterous in-hand manipulation through reinforcement learning and imitation learning, and a manipulation graph would be built to finish kinds of complex target positions and orientations. At this moment. the policy learning in simulation environment has finished, and the next step is to transfer it to real hand.

Learning-based pose estimation and control of Festo BionicSoftHand

ETH Zurich, Oct. 2019 - mar. 2020
Supervisor: David Hoeller, Dr. Martin Wermelinger, Prof. Marco Hutter

This project addressed the problem of pose estimation and control of soft robot hand. As soft hand is of no rigid body dynamics constraints, it’s difficult to model and predict the pose. We proposed a novel framework for dexterous manipulation of soft hand, which combined state-of-the-art methods for learning-based modelling and reinforcement learning. What’s more, we transferred it to the real hand system and verified the efficiency of the whole pipeline through some dexterous manipulation tasks.

ICRA2018 - Tidy Up My Room Challenge (Inherited from Amazon Robotics Challenge)

Shanghai Jiao Tong University, Dec 2017 - May 2018
Supervisor: Prof. Weiming Wang, Prof. Cewu Lu

The challenge aims to develop a system that can identify objects that are out of place and relocate them to their designated location based on a comprehensive list of appropriate places for objects. This list utilizes a simple "object:furniture" relation model. To accomplish this, we developed a cutting-edge object detection network that utilizes the state-of-the-art Mask RCNN algorithm to identify both known and unknown objects from the COCO dataset with 100% accuracy. To achieve accurate and efficient object relocation, we employed an advanced grasp planning method based on the detected masks, which resulted in a grasp accuracy of 92%.

Description: Sustainable Cities Needed! The International City Management Group needs help for implementing smart growth theories into city design around the world. The detailed information can be seen here.

  • A three dimensional baseline cube model is developed to measure the success of smart growth of a city.
  • Economic Development Index (EDI), Social Justice Index (SJI) and Environment Performance Index (EPI) are defined to evaluate city development.
  • The most influential factors in city budget is shed light on and a smart growth plan is put forward.
  • DJI Summer Camp - Aircraft grasping and delivery

    Shenzhen DJI Innovation and Technology Co., Ltd., July 2016 - August 2016
    Supervisor: Shuo Yang (Former DJI Director of Intelligent Navigation Technology)

    Description: Two kinds of dolls (Hippos and octopuses) are needed to grasp and delivered by a drone, involving object detection, path planning and mechanical design.

  • Inspired by tentacles of octopuses, a grasping and releasing mechanical structure was designed, and the overall weight was only 20g, guaranteeing the flight performance of the aircraft.
  • NC programming and carbon fiber processing by hand with an numerical control machine.
