Research on Control Concepts
• Behavior-based control architecture for complex autonomous robotic
systems
• Action-oriented and Perception-oriented design
• Verification and validation of control approaches
• Development of framework to foster reuse of components
• Computer architecture and electronics
11 Ch. Armbrust
Behavior-Based Architecture iB2C
• Uniform behavior modules
• System is composed of many behaviors instead of large, monolithic structure
• Behavior B defined as B=(r,a,F) with
– Input vector e and output vector u sensor/control data
– Stimulation s in [0,1] gradually activating the behavior
– Inhibition i in [0,1] gradually deactivating the behavior
– Activation ι=s∙(1-i)
– Activity a in [0,1] indicating how much B is doing
– Target rating r in [0,1] assessing current situation
– Transfer function F(e,s,i)=u implementing the functionality
