ReDySim

Recursive Dynamic Simulator (ReDySim) is a general purpose software, essentially consisting of recursive order (n) inverse and forward dynamics algorithms (Shah et al., 2009, 2010) for simulation and control of open and closed-loop robotic or multibody systems . The ReDySim delves upon the Decoupled Natural Orthogonal Complement (DeNOC) based approach for dynamic modeling. The specialty of this software exists in its recursive nature. The algorithms are much faster than or as fast as the most efficient algorithms proposed in the literature. The gain in computational time is more as the number of links and joints in the system increase.

The  latest version as on September 2026 has a user-friendly GUI independent of any commercial software. For those who used RoboAnalyzer software may find it very convenient.
