**2. Concepts and technologies**

Exoskeleton and humanoid robot technology applied in construction and building technology demands for key concepts and technologies. At fists the degree of autonomy of the designed system has to be considered. Further, the fusion of speed, power and accuracy of robotic systems with human intelligence and flexibility within one system and the operation of humans and robots in dynamic environments can be supported by recent advancements in sensing and interface technology, actuator and control system technology and system design strategies. Further, a slow but continuous break up of strict borders between professions helps to create interdisciplinary cooperation and consortia which are able handling the complex challenges of man-robot cooperation. At the end of this chapter we present a categorization of exoskeleton and humanoid robot technology applied in construction and building technology based on the system complexity.
