Communication diagram for KUKA KUBE test-bed hardware-in-the-loop experiments. Blue rectangles with continuous borders represent hardware components. Green, inner rectangles with dashed borders represent software components that were created or modified to perform the experiment. Brackets around parameters are added to improve subscript readability
