Development of a Minimalistic Pneumatic Quadruped Robot for Fast Locomotion

Narioka, K., Rosendo, A., Spröwitz, A., Hosoda, K.

In Proceedings of the 2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012, pages: 307-311, IEEE, Guangzhou, 2012 (inproceedings)

Abstract
In this paper, we describe the development of the quadruped robot ”Ken” with the minimalistic and lightweight body design for achieving fast locomotion. We use McKibben pneumatic artificial muscles as actuators, providing high frequency and wide stride motion of limbs, also avoiding problems with overheating. We conducted a preliminary experiment, finding out that the robot can swing its limb over 7.5 Hz without amplitude reduction, nor heat problems. Moreover, the robot realized a several steps of bouncing gait by using simple CPG-based open loop controller, indicating that the robot can generate enough torque to kick the ground and limb contraction to avoid stumbling.

Locomotion through Reconfiguration based on Motor Primitives for Roombots Self-Reconfigurable Modular Robots

Bonardi, S., Moeckel, R., Spröwitz, A., Vespignani, M., Ijspeert, A. J.

In Robotics; Proceedings of ROBOTIK 2012; 7th German Conference on, pages: 1-6, 2012 (inproceedings)

Abstract
We present the hardware and reconfiguration experiments for an autonomous self-reconfigurable modular robot called Roombots (RB). RB were designed to form the basis for self-reconfigurable furniture. Each RB module contains three degrees of freedom that have been carefully selected to allow a single module to reach any position on a 2-dimensional grid and to overcome concave corners in a 3-dimensional grid. For the first time we demonstrate locomotion capabilities of single RB modules through reconfiguration with real hardware. The locomotion through reconfiguration is controlled by a planner combining the well-known D* algorithm and composed motor primitives. The novelty of our approach is the use of an online running hierarchical planner closely linked to the real hardware.

Passive compliance for a RC servo-controlled bouncing robot

Meyer, F., Spröwitz, A., Berthouze, L.

Advanced Robotics, 20(8):953-961, 2006 (article)

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.

Project course "Design of Mechatronic Systems"

Koch, C., Spröwitz, A., Radler, O., Strohla, T.

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.
