Abstract
We present a Bluetooth scatternet protocol (SNP) that provides the user with a serial link to all connected members in a transparent wireless Bluetooth network. By using only local decision making we can reduce the overhead of our scatternet protocol dramatically. We show how our SNP software layer simplifies a variety of tasks like the synchronization of central pattern generator controllers for actuators, collecting sensory data and building modular robot structures. The whole Bluetooth software stack including our new scatternet layer is implemented on a single Bluetooth and memory chip. To verify and characterize the SNP we provide data from experiments using real hardware instead of software simulation. This gives a realistic overview of the scatternet performance showing higher order effects that are difficult to be simulated correctly and guaranties the correct function of the SNP in real world applications.

Passive compliance for a {RC} servo-controlled bouncing robot
Passive compliance for a RC servo-controlled bouncing robot

Abstract
A novel and low-cost passively compliant mechanism is described that can be used with RC servos to actuate legged robots in tasks involving high dynamic loads such as bouncing. Compliance is achieved by combining visco-elastic material and metal parts. Joint response to dynamic loads is evaluated using real-world experiments and force data are obtained from a Lagrangian analysis of the system. The experimental results demonstrate the applicative potential of this mechanism.

In IEEE International Conference on Mechatronics, pages: 69-72, IEEE, Budapest, 2006 (inproceedings)

Abstract
The course "Design of Mechatronic Systems" at Technische Universität Ilmenau imparts the systematic procedure of mechatronic design. This paper shows the main features of VDI Guideline 2206, which provides the structured background for students education in mechatronics. Furthermore practical teaching experiences and results from the course are described.
