Scientists at MPI-IS have developed electrically driven robotic components, called HEXEL modules, which can snap together into high-speed reconfigurable robots. Magnets embedded along the outside of the modules allow them to electrically and mechanically connect to other modules, forming robots with diverse shapes and capabilities.
HEXEL modules are a promising technology for use in resource-limited environments, such as on space or rescue missions, and can be used to construct versatile robots from redundant parts, altogether promoting a sustainable robot design.
"Combining soft and rigid components in this way enables high strokes and high speeds. By connecting several modules, we can create new robot geometries and repurpose them for changing needs," says Ellen Rumley, a visiting researcher from the University of Colorado Boulder. She and Zachary Yoder, who are both Ph.D. students working in the Robotic Materials Department, are co-first authors of the publication.
"In general, it makes a lot of sense to develop robots with reconfigurable capabilities. It's a sustainable design option -- instead of buying five different robots for five different purposes, we can build many different robots by using the same components. Robots made from reconfigurable modules could be rearranged on demand to provide more versatility than specialized systems, which could be beneficial in resource-limited environments'', Yoder concludes.
