In　recent　years,　designing　a　soft　robot　that　can　jump　continuously　and　quickly　explore　in　a　narrow　space　has　been　a　hot　research　topic.　With　the　continuous　efforts　of　researchers,　many　types　of　actuators　have　been　developed　and　successfully　employed　to　actuate　the　rapid　locomotion　of　soft　robots.　Although　these　mechanisms　have　enabled　soft　robots　with　excellent　movement　capabilities,　they　largely　rely　on　external　energy　supply　cables,　which　greatly　limits　their　applications.　Therefore,　it　is　still　a　big　challenge　to　realize　the　unconstrained　movement　of　the　soft　robot　and　the　flexible　adjustment　of　the　movement　direction　in　a　narrow　space.　Here,　a　wireless　magnetically　controlled　soft　jumping　robot　with　single-leg　is　proposed,　which　can　achieve　continuous　and　rapid　jumping　motion.　What＇s　more　interesting　is　that　by　changing　the　frequency　and　waveform　of　the　control　signal,　this　soft　robot　can　easily　switch　between　forward　and　backward　motions.　This　motion　direction　switching　function　enables　the　magnetically　controlled　soft　robot　to　return　to　the　initial　position　without　adjusting　the　direction　when　it　completes　the　operation　in　a　narrow　pipe　or　takes　the　wrong　path,　which　greatly　improves　the　motion　efficiency　of　the　soft　jumping　robot　and　broadens　its　application　field.　©　2023,　Jilin　University.
