I used Unified Robot Description Format (URDF), which is an XML format for representing a robot model. This will probably result in necessary changes on the URDF parser and the way URDF models are distributed in ROS. Joint force/torque and upper regulation velocity are taken from the URDF file. (URDF), and this paper proposes a method for searching the URDF for active serial chains in individual robot systems. Viewed 99 times 1 $\begingroup$ Since urdf format serves the purpose of kinematic model but also extends for dynamical properties such as mass,moment of inertia and centre of masses, can it be considered a viable dynamical model of a robot. URDF Generator for Manipulator Robot. If you find that this asset is not as advertised, please contact the publisher. Note that geometry will not necessarily be loaded when the robot is returned.
