Robot Modeling and Simulation

Kinematic and motion models, Gazebo co-simulation

When working with robots, modeling and simulation enable you to prototype algorithms quickly and test scenarios by mimicking the behavior of real-world systems. These functions provide kinematic models for both manipulators and mobile robots to model their motion. The toolbox also supports synchronized stepping of Simulink® with Gazebo to design your robotics algorithms with physical simulations.
