Introduction

In the realm of multibody modeling, the ability to efficiently and accurately simulate complex systems is crucial for various applications, including robotics, mechanical engineering, and biomechanics. One of the key challenges in multibody modeling is the generation of equations that describe the dynamics of the system. This is where Robotran comes into play, a powerful tool that uses symbolic generation to create multibody equations, making simulations more efficient and portable.

What is Robotran?

Robotran, short for "ROBOt-TRANslator," is a symbolic multibody program developed at the University of Louvain (UCL) in the field of robotics. Its primary function is to symbolically compute inverse dynamical models, which are essential for understanding the behavior of complex systems. Over time, the program has been expanded to include direct models and closed-loop formulations, enabling it to tackle a wide range of applications, from road and railway vehicles to actuators, parallel manipulators, mechanisms, and even the human body.

History of Symbolic Multibody Programs

The concept of symbolic multibody programs dates back to the 1980s, when researchers began exploring ways to generate equations that describe the dynamics of complex systems. These programs use mathematical techniques to create symbolic expressions that represent the equations of motion, making it possible to analyze and simulate the behavior of the system. Robotran is one of the pioneering programs in this field, and its development has been instrumental in advancing the field of multibody modeling.
