# Path Planning What is path planning? We'll explore digital fabrication toolpath planning, both subtractive and additive. We'll also explore robotic path planning with a collaborative flavor. # [Computational Geometry and Subtractive Path Planning](https://fab.cba.mit.edu/classes/865.24/people/Fangzheng/path%20planning/Path_Planning.html) How to represent objects in 1D, 2D, and 3D? Deep-dive into Mods subtractive path planning # [Additive path planning](https://fab.cba.mit.edu/classes/865.24/topics/path_planning/additive.html) Geometry validation, mesh repair, Slicers, and infill patterns # [Robotic Path Planning](https://fab.cba.mit.edu/classes/865.24/topics/path_planning/robotic.html) Map representation, graph algorithms, random sampling algorithms, machine learning # [Collaborative Path Planning](https://fab.cba.mit.edu/classes/865.24/topics/path_planning/collaborative.html) Multi-robot planning, synchronization, networks
