Industrial Robot

An identification benchmark dataset for a full robot movement with a KUKA KR300 R2500 ultra SE industrial robot is presented. It is a robot with a nominal payload capacity of 300 kg, a weight of 1120 kg, and a reach of 2500mm. It exhibits 12 states accounting for position and velocity for each of the 6 joints. The robot encounters backlash in all joints, pose-dependent inertia, pose-dependent gravitational loads, pose-dependent hydraulic forces, pose- and velocity-dependent centripetal and Coriolis forces as well as nonlinear friction, which is temperature-dependent and therefore potentially time-varying. Prepared datasets for black-box identification of the forward or the inverse robot dynamics are provided. Additional to the data for the black-box modeling, we supply high-frequency raw data and videos of each experiment. A baseline and figures of merit are defined to make results comparable across different identification methods.

A detailed formulation of the identification problem can be found here, and in this presentation. All the provided files and information on the industrial robot dataset can be found here.
