Jink.jl

Julia package for differential multi-task inverse kinematics

Features

• This package solves multi-task inverse kinematics by composing the multiple motion tasks as a single Quadratic Program and solving it using OSQP via the JuMP.jl mathematical programming interface.

• Jink.jl is designed to have a general API that allows you to easily adapt it to your robot of choice. All you have to do is to create a Julia sub-module for your robot that exports all desired kinematics as functions.As examples, this package provides sub-modules for the PickleRick planar humanoid robot and the Digit robot.
