RESUMO

This work presents a dynamic simulator of articulated rigid bodies. The bodies are described by their physical and geometric properties and are assumed to be convexo The input for the simulator is, in addition to the description of the bodies, an initial valid state and a set of external forces and torques that act on the bodies over the time. Articulations between the bodies, if any, are also specified. They represent mechanical joints that constrain the movement of the system of bodies. Given the data above, we create a set of equations of movement, known as Lagrange equations, which define how the system will evolve over the time (they consist of a system of second-order ordinary differential equations). The trajectory of the system of bodies is created numerically integrating the Lagrange equations. This trajectory obeys the laws of mechanics. Any collisions that eventually occur during the animation are also treated by the simulator
