RIMRES

Reconfigurable Integrated Multi Robot Exploration System

The aim of the project is the development of core technologies for modular, reconfigurable robotic systems to support the efficient and robust execution of complex tasks in uncooperative and difficult-to-access areas. Besides new methods for autonomy, navigation, and locomotion, the focus is on a highly modular system concept consisting of modules for different functions, i.e., locomotion, energy supply, data recording, autonomy, and navigation which are intended to be compatible with each other and will be linked via a uniform mechatronical interface.

Robot Teams for Lunar Exploration

RIMRES (Reconfigurable Integrated Multi-Robot Exploration System) is a joint project of the DFKI Robotics Innovation Center and the ZARM (Center of Applied Space Technology and Microgravity).

Within this project, a complex demonstration scenario is set up demonstrating a lunar pole exploration. The focus lies on an improved surface mobility which is achieved by employing single robot systems with innovative morphologies and by combining heterogeneous robots into one overall system.

The hybrid wheeled-leg rover SHERPA developed in the RIMRES project offers not only a relatively energy-efficient locomotion in moderately unstructured terrain, but, as a result of the active suspension system, the rover provides increased mobility so as to free itself if getting stuck and to react flexibly to unforeseen circumstances.

The second mobile system in RIMRES is the six-legged walking Scout robot CREX for the exploration of the interior of lunar craters. It is transported by Sherpa to the crater rim, deployed, and starts climbing into the permanently shaded regions of the crater (see video at bottom of page). CREX is based on previous experiences gained in the SpaceClimber project.

Research activities also focus on the modularity of exploration systems: a uniform electromechanical interface serves to combine mobile systems either with each other, or with so-called payload items which, in turn, can also be combined among themselves. The payload items are used to assemble scientific and technological payloads or to enhance the capabilities of the mobile systems. This way, a task-specific reconfiguration of the systems beomes possible.
