This paper describes a navigation architecture for mobile robots, structured as a set of nested control loops whose depth is related to their knowledge of the environment and the ability to drive the actuator, and involving as well competing behaviors that will ultimately generate the robot motion. The architecture has been successfully used on a mobile platform to support three-dimensional environment reconstruction tasks. The architecture may be classified as belonging to the hybrid type but

A monitorized data path ensures the construction of the most adequate and safe motion, as well as an unlimited set of behaviors depending on the already known and perceived environment. Added concepts of path recovering and assisted navigation fulfill the demands for the three-dimensional acquisition scheme involved. Some comparison with existing architectures is carried out throughout the text. The versatility and robustness of the architecture are supported by extensive results.
