mink is a direct port of pink which uses Pinocchio under the hood. Stéphane Caron, the original author of pink, is a role model for open-source software in robotics. This library would not have been possible without his work and assistance throughout this project.

mink also heavily adapts code from the following libraries:

• The lie algebra library that powers the transforms in mink is adapted from jaxlie.
• The collision avoidance constraint is adapted from dm_robotics's LSQP controller.
