**2.7 Categorization according to system complexity**

In order to be able to design work tasks and application scenarios for exoskeletons and humanoids in construction and building technology we classify robotic systems according to system complexity. With complex systems we mean systems that consist of a number of subsystems and sub-elements. Accordingly, element technologies are basic technologies. They can be applied as standalone systems or combined as sub-elements to more complex subsystems. Subsystems denote e.g. partial exoskeletons (exoskeleton for lower body part/feet, Exoskeleton for upper body part). A total system consists of several sub-systems; here we mean e.g. total exoskeletons or mobility robots. Autonomous robot systems (humanoid robots, service robots) and distributed robot systems can operate highly autonomous and are able to support robot service on city scale. They stand for highly complex robot systems built up by multitude of element technologies, subsystems and autonomous robot systems.
