چکیده

In the broader context of quadrupedal locomotion, this overview article introduces and compares two platforms that are similar in structure, size, and morphology, yet differ greatly in their concept of actuation. The first, ALoF, is a classically stiff actuated robot that is controlled kinematically, while the second, StarlETH, uses a soft actuation scheme based on highly compliant series elastic actuators. We show how this conceptual difference influences design and control of the robots, compare the hardware of the two systems, and show exemplary their advantages in different applications. Zusammenfassung Der vorliegende Beitrag vergleicht zwei Laufroboter, die sich in Hinblick auf Struktur, Größe und Morphologie stark ähneln, jedoch im Antriebskonzept klar unterscheiden. Während es sich beim ersten System, ALoF, um einen klassisch angetriebenen Roboter handelt der kinematisch geregelt wird, besitzt der zweite Roboter, StarlETH, Federelemente im Antriebsstrang. Diese ermöglichen eine weiche, kraftgeregelte Aktuierung. Der Beitrag zeigt wie dieser Unterschied Design und Regelung der Roboter beeinflusst, vergleicht die Hardware und erläutert Vorund Nachteile in verschiedenen Anwendungsfällen.

High-precision force control using selective compliant mechanisms

In many applications, robots can benefit from compliant elements integrated in their structure: Shock resistance and superior force control performance are two out of many advantages compared to stiff robots. In contrast, stiff robots are often superior compared to compliant (soft) robots in terms of position accuracy and bandwidth. We are trying to merge the best of these two worlds by combini...

Controlling Dynamic Gaits for Quadrupedal Robots

Bridging the gap between the skill sets of legged robotic systems and that of real animals is one of the major challenges in the field of robotics. Our long-term goal is to develop and control quadrupedal robots that are able to operate semiautonomously, i.e. they are only guided by users through highlevel velocity commands, such as move forward at 1 m/s, or turn with 0.5 rad/s. To achieve this...

Role of Spine Compliance and Actuation in the Bounding Performance of Quadruped Robots

There is so far no quadruped robot that exhibits locomotion performance matching to that shown by animals every day. Both differences in general design concepts, in available materials and actuation mechanisms as well as a lack of understanding on the control of the robots’ actuators contribute to the current performance gap between robotic platforms and their biological counterparts. While for...
