The　pneumatic　artificial　muscle(PAM)　has　widespread　applications　from　prosthetics,　humanoid　robots,　continuum　robots,　and　soft　robots.　Traditional　PAMs　imitate　the　movement　mode　of　biological　mus-cles,　and　control　the　contraction　of　muscles　through　the　increase　or　decrease　of　internal　pressure.　PAMs　have　the　advantages　of　light　weight,　high　cleanliness,　natural　flexibility　and　safety.　However,　they　also　have　problems　such　as　a　low　contraction,　difficult　to　change　contraction　force　based　on　demand,　and　hard　to　adapt　to　soft　systems.　Human　muscle　is　a　kind　of　bundle　structure.　Multiple　muscle　fibers　work　together　to　make　the　muscle　structure　more　stable　and　provide　great　power　for　human　beings.　Thus,　we　propose　an　improved　Multi-connector　pneumatic　artificial　muscle(MPAM),　which　is　more　similar　to　the　structure　of　human　muscle.　Six　self-made　McKibben　muscles,　only　7　mm　in　diameter,　are　fixed　into　a　bundle　through　Y-shaped　multi-way　valves.　This　structure　can　produce　8%　more　contraction　ratio　than　the　traditional　McKibben　muscles,　and　the　number　of　muscle　fibers　can　be　increased　or　decreased　according　to　different　application　scenarios.　Due　to　its　detachable　nature,　MPAM　can　be　applied　to　a　wider　range　of　fields.　The　MPAM　provide　a　simple　new　option　for　soft　robotic　actuation　and　has　potential　to　push　the　development　of　the　soft　robot　assistant　suit.　©　2022　IEEE.
