Research summary

My work focuses on algorithms and data structures for navigational planning in outdoor scenarios while using semantic information. Semantic maps simplify the interaction between humans and robots, and also the way we program the robots. I focus on new outdoor navigation approaches for mobile robots using reconstructed layered meshes for navigational planning. An on-line capable semantic map approach is my research goal. I am researching for a new data structure combining the strength of octrees and meshes fulfilling the needs for online capable semantic maps which are useful for navigational planning for many different robots.
