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.
