Researcher

Siyuan Feng

Siyuan Feng researches robot control and learning. He earned a robotics PhD in February 2016 and served as control lead for Team WPI-CMU in the DARPA Robotics Challenge. In 2022, he coauthored Iterative Residual Policy for manipulating deformable objects while affiliated with Toyota Research Institute. He later coauthored Diffusion Policy, first submitted in March 2023, which uses denoising diffusion to generate robot actions from visual observations.

Timeline

  1. 2012–2016

    Control for humanoid robots

    Feng worked on full-body humanoid control beginning in 2012 and served as control lead for Team WPI-CMU in the DARPA Robotics Challenge. He completed a CMU robotics PhD in February 2016 on online hierarchical optimization for humanoid control.

  2. 2022

    Learning from action changes

    Feng coauthored Iterative Residual Policy with a team from Columbia and Toyota Research Institute. The method learns how changes in an action affect a previously observed trajectory. It then adjusts actions online to reach a specified manipulation goal.

  3. 2022

    Testing ropes and cloth

    The team tested the policy by whipping a rope toward a target and swinging cloth toward a target pose. The policy transferred from simulation to real dynamics and new objects. Feng was affiliated with Toyota Research Institute at the time.

  4. 2023

    Diffusion for robot actions

    He coauthored Diffusion Policy, initially submitted in March 2023. The method represents a robot’s visuomotor policy as a conditional denoising process. The expanded paper describes visual conditioning and repeated planning over an action sequence.
