Our research direction is to develop more robust control algorithms and build more agile and anthropomorphic robots. We are currently developing control algorithms for walking robots based on the concept of passive dynamic walking (PDW). PDW was first introduced by McGeer, and he showed that a simple biped can walk down a gentle slope, about 2 to 3 degrees, without any actuations or control. It walks down a slope powered by only gravity. He said that the Wright brothers invented the world-first powered flight, but, before the Wright brothers, researchers studied gliders that can fly without any control. As a result, they discovered some principles of aerodynamics, and based on the understanding, the Wright brothers invented their powered flight. So, when it comes to dynamic robot control, instead of applying some artificially generated forces, our approach is to study natural dynamics first, discover some principles of dynamic walking, and then control robots based on the new understanding.

Research Fields

1. Advanced control algorithms for walking robots
2. Hybrid system control
3. Gait generation, stabilization, and optimization.
4. 3D dynamic walking and running
5. Humanoid robots
