sequence and motion planning for robotic spatial extrusion

Project description

pychoreo is a sequence and motion planning engine that allow you to print the following cool structures (and many more!) with ease:

Voronoi extrusion video

Note :pushpin:

  • In the summer of 2019, pychoreo will be integrated into the compas_fab infrastructure. Stay tuned! :beers:
  • The ROS implementation of choreo can be found here: choreo.

Algorithms behind Choreo:

  • Automated sequence and motion planning for robotic spatial extrusion of 3D trusses, Constr Robot (2018) 2:15-39, Arxiv-1810.00998
Applications of Choreo:

  • Spatial extrusion of Topology Optimized 3D Trusses, IASS 2018, IASS paper link

0.2.0

Added

  • SparseLadderGraph completed
  • export planned trajectory for extrusion
  • add parsing function for visualizing saved extrusion trajectories
  • from_data methods for Trajectory and subclasses
  • tagging print processes with ground/creation/connect in the test function
  • infinite pose sampler added for extrusion case when using sparse ladder graph to solve

Minor

  • is_any_empty utility function for checking ik sol list of lists
  • reset_ee_pose_gen_fn for easier resetting generator

Fixed

  • fix nested empty list detection bug in is_any_empty
  • add disabled_collisions argument to the extrusion transition_planner

Changed

  • extrusion export save lin_path’s poses as 4x4 tform matrix (there’s some disagreement in quaterion in compas.Frame.from_quat?)
  • move extrusion test fixtures into a separate fixture module
  • ladder graph interface broken into from_cartesian_process_list, from_cartesian_process, from_poses to increase code reuse

0.1.1

Added

  • cartesian process class for modeling general linear movement in the workspace
  • ladder graph interface using the Cartesian process class
  • Trajectory class for modeling result trajectory in different contexts (inherited classes)
  • display_trajectories for extrusion
  • some simple exceptions added for LadderGraph and DAGSearch
  • subprocess modeling to have a more detailed control over Cartesian process modeling
  • add exhaust_iter method to CartisianProcess which resets the generator
  • add template class GenFn for generating functions
  • add PrintBufferTrajectory to model approach/retreat trajectories

Changed

  • move transition planning to application context.
  • conform to the latest pybullet_planning

Removed

  • assembly_datastructure
  • the old extrusion.run module, moved to the test file

Fixed

Deprecated

0.0.1

Added

  • Initial version
