Aiming　at　the　problem　of　multi-robot　hunting,　this　paper　analyzes　the　influence　of　distribution　of　hunters　on　hunting　efficiency.　By　analyzing　the　angles　made　by　robots,　together　with　the　conditions　of　successfully　capturing　objective　robot,　an　angle　first　strategy　that　takes　the　angles　made　by　the　robots　into　account　first　when　hunters　surround　objective　robot　is　designed.　Finally,　the　simulation　in　virtue　of　Multi　Robot　Simulator　shows　that　the　success　ratio　increases　and　the　time　cost　is　cut　down.
