Extensive manipulation capabilities and reliable behavior at autonomous robot assembly

Different powerful extensions and improvements of the control architecture of an autonomous robot are presented. They are used to increase the reliability of robot assembly and to reach a sufficient behavior. The decision to use autonomous assembly robots in an industrial manufacturing setting depends mainly on the reliability of such a system and the extension of its manipulation capabilities. The Karlsruhe Autonomous Mobile Robot (KAMRO) is a robot system that is able to take on, and to execute, assembly tasks autonomously. Although the robot was able to work without human intervention within a limited scope, the reliability of the system was unfortunately not adequate for large-scale applications. This paper describes how the reliability has been improved and which experiments were performed to evaluate the concept
