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…
