By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – Investigators publish new report on Ro botics. According to news originating from Hangzhou, People’s Republic of China, by NewsRx correspondents, research stated, “Self-sustained motions are widespre ad in biological systems by harvesting energy from surrounding environments, whi ch inspire scientists to develop autonomous soft robots. However, most-existing soft robots require dynamic heterogeneous stimuli or complex fabrication with di fferent components.” Financial support for this research came from National Natural Science Foundatio n of China (NSFC). Our news journalists obtained a quote from the research from Zhejiang University , “Recently, control of topological geometry has been promising to afford soft r obots with physical intelligence and thus life-like motions. Reported here are a series of closed twisted ribbon robots, which exhibit self-sustained flipping a nd rotation under constant light irradiation. Both M & ouml;bius s trip and Seifert ribbon robots are devised for the first time by using an identi cal hydrogel, which responds to light irradiation on either side. Experiment and simulation results indicate that the self-regulated motions of the hydrogel rob ots are related to fast and reversible response of muscle-like gel, self-shadowi ng effect, and topology-facilitated refresh of light-exposed regions. The motion speeds and directions of the hydrogel robots can be tuned over a wide range. Th ese closed twisted ribbon hydrogels are further applied to execute specific task s in aqueous environments, such as collecting plastic balls, climbing a vertical rod, and transporting objects. This work presents new design principle for auto nomous hydrogel robots by benefiting from material response and topology geometr y, which may be inspirative for the robotics community. A series of M & ouml;bius strip and Seifert ribbon robots are devised by using identical slender muscle-like anisotropic hydrogel. These closed twisted ribbon hydrogels exhibit continuous flipping and rotation under static light irradiation.”
