Audio navigation of rescue robots based on speech recognition
-
摘要: 在發生火災或地震的建筑物內,由于煙霧或墻體倒塌等原因,救援機器人往往無法通過視覺、超聲和紅外等傳感器直接發現建筑物內不可見區域或者其他房間中呼救的目標.利用聲音信號波長較長可以衍射繞過障礙物傳播的特性,結合現有的語音識別技術,開發出基于聽覺的救援機器人導航系統.該系統使機器人可以在全局運動控制中跟蹤幸存者的呼救聲并向幸存者移動.通過相關實驗驗證了基于聽覺的救援機器人導航方法的可行性.Abstract: A rescue robot often can not directly find the target shouting for help which is in other rooms or invisible places in the building by using visual, ultrasonic or infrared ray sensors because of smoke or collapsed walls. The sound can diffract over obstacles due to the long wavelength of audio signals. Combined with the speech recognition technology, an audio navigation system was developed for the rescue robot. This navigation system makes it feasible to guide the rescue robot run to the target shouting for help in global motion control. Experimental results verified the feasibility of the navigation system.
