**2.1 Exoskeletons, humanoids and autonomy**

Robotic systems can have varying degrees of autonomy. Robots with a low degree of autonomy require detailed pre-programming or detailed real-time operation of a human person. Robots with a medium degree of autonomy only require supervision and an operator only has to assign tasks for which the robot autonomously finds sufficient solutions. Robots with a high degree of autonomy are capable of performing tasks and making decisions without major human interference. Especially in the area of construction and building technology the degree of autonomy of a system plays an important role as e.g. construction sites and service environments within buildings often provide dynamic environments and unstructured, complex work tasks. One can address this problem by modifying or structuring the environment or work task on the one hand or by advancing robot control technology or the application of artificial intelligence on the other.
