QuIRK is an interactive Matlab command line interface for constructing systems of rigid bodies and joint constraints

QuIRK is an interactive Matlab command line interface for constructing systems of rigid bodies and joint constraints, solving the equations of motion of those systems when subject to various force expressions, displaying and animating solved systems, and extracting information about the state history and energetics of those systems. The goals of QuIRK are modularity and ease of operation rather than computational efficiency. It is based on quaternion attitude representations of bodies for full generality, and joint constraints are written in terms of the second derivative of body quaternions. Hence: Quaternion-state Interface for Rigid-body Kinetics.

QuIRK uses the Udwadia-Kalaba pseudoinverse method for constructing the equations of motion of constrained systems, augmented for singular mass matrices by Udwadia and Phohomsiri, with some additions to accommodate quaternion states.

QuIRK was developed in the course of a graduate research project. It supports complex multibody systems (with no limits on the numbers of bodies or constraints, as long as your system is capable enough) and simulates their motion subject to user-specified forces on all bodies, forces between bodies, or potential energy functions. There is a predefined set of joint constraints, but with a little understanding of the Udwadia-Kalaba technique, any arbitrary joint kinematics can be defined. The full state history of all bodies is available to the user for analysis (with some analysis tools build into this code).
