With　the　robot　gradually　used　in　many　fields　of　production　and　life,　safety　has　become　one　of　the　important　research　directions　of　robot.　According　to　different　research　objects　for　robot　safety,　research　status　of　robot　safety　at　home　and　abroad　is　expounded　from　two　parts,　namely　self-safety　and　interaction　safety.　The　role　of　mechanical　structure　design　and　control　algorithms　in　improving　robot　safety　is　analyzed.　On　this　basis,　the　existing　problems,　such　as　too　traditional　structure　design　method,　weak　judgment　of　unexpected　situation　and　lack　of　control　compliance　under　complicated　conditions,　are　analyzed,　which　limit　the　popularization　and　application　of　robots.　The　development　trend　of　robot　safety,　such　as　rigid　flexible　hybrid　mechanism,　accurate　and　fast　environment　judgment　and　good　compliance　control,　is　proposed.　©　2018,　Editorial　Board　of　JBUAA.　All　right　reserved.
