pychoreo 0.1.1

sequence and motion planning for robotic spatial extrusion

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

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.

Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

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

TODO

• need to regulate the use of ik_joints or ik_joint_names for user interfaces

0.0.1

Added

• Initial version
