Does robotics define metallic droids? not really, a group of researchers is working to create the next generation of robots called HASEL Artificial Muscles (hydraulically amplified self-healing electrostatic), that can react to applied voltage with a wide range of motions.
HASEL Artificial Muscles
The Engineering Center is using a new generation of HASEL actuators or artificial muscles, a technology that is not really new but is showing off exceptional progress. The researchers are trying to imitate muscular functioning consequently by giving way to a new generation of “soft robots”.
These soft robots contain a tremendous potential for the future application, which adapts to dynamic environments and well-suited closely to interact with humans. Notably, the soft robots can perform a variety of tasks, which includes grasping delicate objects (such as raspberry or a raw egg) or lifting heavy objects.
The Keplinger (research group) developed soft robot are electrically activated devices capable of mimicking the expansion and contraction of natural muscles, which can self-sense their movements and self-heal from electrical damage and the major addition is that it can be built from a wide range of (low-cost) materials.
How Does A HASEL Artificial Muscles Behave?
The HASEL device consists of an elastomeric shell that can take different shapes inside an electrically insulating liquid connected to a pair of opposed electrodes. So, when a tension is applied, the liquid moves, which apparently changes the shape of the elastomer.
