Efficient Terrain Map Using Planar Regions for Footstep Planning on Humanoid Robots

ICRA 2024poster

Humanoid robots possess the ability to perform complex tasks in challenging environments. However, they require a model of the surroundings in a representation that is sufficient enough for downstream tasks such as footstep planning. The maps generated by existing mapping algorithms are either spars…

Efficient, Dynamic Locomotion through Step Placement with Straight Legs and Rolling Contacts

ICRA 2024poster

For humans, fast, efficient walking over flat ground represents the vast majority of locomotion that an individual experiences on a daily basis, and for an effective, real-world humanoid robot the same will likely be the case. In this work, we propose a locomotion controller for efficient walking ov…

Physically Consistent Online Inertial Adaptation for Humanoid Loco-manipulation

IROS 2024poster

The ability to accomplish manipulation and locomotion tasks in the presence of significant time-varying external loads is a remarkable skill of humans that has yet to be replicated convincingly by humanoid robots. Such an ability will be a key requirement in the environments we envision deploying ou…

Integrable Whole-Body Orientation Coordinates for Legged Robots

IROS 2023poster

Complex multibody legged robots can have complex rotational control challenges. In this paper, we propose a concise way to understand and formulate a whole-body orientation that (i) depends on system configuration only and not a history of motion, (ii) can be representative of the orientation of the…
