<p>
Hi there! I'm Chong Liu, a Robot Control Engineer based in Shenzhen, China. I hold
a master's degree in Mechanical Engineering from Columbia University, specializing
in Robotics and Control.
</p>
<p>
I'm currently focused on humanoid robot reinforcement learning and imitation
learning for motion control, working at BridgeDP Robotics Co., Ltd. to deliver
customized motion control solutions for client humanoid robots.
</p>
<p>
I'm fascinated by designing and building advanced, life-like robots, and applying
robotics technology to help people in need. This webpage contains my project
documentation and resources to start on robotics from scratch. Together, let's
make the world a better place!

Fourier Analysis Guided Cable Actuator Design for Coordinated Walking Assistance

<p>
Cable-driven exoskeletons add minimal inertia and restrictions to the user's leg
while still providing feedback and quantitative measures of the user's
performance. This work proposes a Fourier analysis guided approach to reduce the
number of actuated motors needed for cable-driven exoskeletons in walking
assistance.
