| Recently, researchers at Harvard University have developed a platform for creating 3D-printed flexible robots with embedded sensors that detect movement, stress, touch, and temperature. The researchers call it a 'ground-based' Progress'.  Two of the world's leading research institutes do not often exist in the same university, but most do not like Harvard University, John A. Paulson School of Engineering and Applied Science (SEAS) and the Wyss Institute of Bio-inspired Engineering have recently jointly developed 3D printing platform for creating soft robots. Researchers at Harvard University have been able to build soft robots that can perform a variety of functions: swimming, holding objects and even helping the human heartbeat, however, none of them adequately understands and responds to external stimuli. The new 3D printing platform developed by Harvard has changed all of this, enabling scientists to create flexible robots that sense movement, stress, touch and temperature - a huge leap forward in the field of soft robots and one of additive manufacturing technologies Very exciting application. 'Our research represents a fundamental advance in soft robotics,' commented lead author Ryan Truby. 'Our manufacturing platform easily integrates complex sensor patterns into flexible robotic systems.' The secret of this process is the sensor's own 3D printing, which is made of an organic ionic liquid conductive ink that can be 3D printed in a robot's soft elastomer matrix and soften the sensor before they were rigid . 'So far most of the integrated sensor / actuator systems for soft robots have been very simple,' said Michael Wehner, a former postdoctoral fellow and author of the paper at SEAS. 'By printing ionic liquid sensors directly in these soft systems we are Equipment design and manufacturing have opened up new avenues that will eventually allow true closed-loop control of soft robots. ' The process involved the use of embedded 3D printing technology, a technology pioneered by Jennifer A. Lewis of the Wyss Institute. 'The versatility and design flexibility of this approach is unmatched,' says Truby. "The new inks, combined with our embedded 3D printing process, allow us to combine soft sensing and actuation in an integrated, flexible robot system ' Researchers at Harvard University tested their 3D printing platform and tested inflation pressure, curvature, touch, and temperature by creating a soft robotic grip that says their new technology could "change the way robots are created." They are now Plan to try machine learning to improve soft robot equipment. It is reported that, entitled "to create a soft somatosensory actuator through embedded 3D printing," the research paper has been published in Advanced Materials magazine. Source: 3D Tiger |
