ROS-Industrial Special Project: 5D tool path planner
Pierre Étienne Bézier September 1, 1910 – November 25, 1999; was a French engineer and one of the founders of the fields of solid, geometric and physical modeling as well as in the field of representing curves, especially in CAD/CAM systems. As an engineer at Renault, he became a leader in the transformation of design and manufacturing, through mathematics and computing tools, into computer-aided design and three-dimensional modeling. Bézier patented and popularized, but did not invent the Bézier curves and Bézier surfaces that are now used in most computer-aided design and computer graphics systems.
This project has been developed by the Institut Maupertuis, a French research institute that is working on robotic industrial processes. This project goal is to create an automatic grinding path generator for 6-axis robots working on diverse/random meshes.
Bezier planner generates robot poses (3D trajectory) in harmony with a grinding process. It is able to create rectilinear trajectories on complicated surfaces (3D surfaces) and to dilate them in all directions in order to grind defects with a pass principle.
- ROS indigo version (with the Fanuc package)
- VTK 6.3 or later, you need (this patch)
- The Point Cloud Library version 1.8 or trunk
Bezier has been tested with ROS Indigo under Ubuntu 14.04.

Build
Clone this repository into your catkin source folder and build the workspace:
cd $(catkin_workspace)/src
git clone https://github.com/ros-industrial-consortium/bezier.gitLaunch
roslaunch bezier_application bezier_application.launch filename:=oriented_complicated_mesh.plyIn this example, bezier_application will be launched with oriented_complicated_mesh.ply as input mesh and oriented_complicated_mesh_default.ply as default mesh.
