Factors being considered for control include program editor access security,Preoperation checklist requirements, welding process variable control,and robot manipulator motion overrides. In the latter two categories, manual vocal control is being pared against manual tactile control and fully automatic control in terms of speed of response, accuracy, stability, reliability. And safety. Introduction Voice recognition technology is now recognized as a potential means for easing the workload of operators of plex systems. Numerous applications have already been implemented, are in various stages of development, or are under consideration. These include data entry,control of aircraft systems, and voice identification and verification for security purposes. Voice control has also been proposed for use aboard the space station. One prime area for application would be control of some functions of robots used for intraand extravehicular inspection, assembly, repair,satellite retrieval, and satellite maintenance when a crewmember is serving in a supervisory capacity or the system is operating in a teleoperation mode. Voice control of sensors and process variables would free the crewmember’s hands for other tasks, such as direct control or override of the manipulator motion. Similarly, the workload associated with control of many onboard experiments could be eased through the use of this technology. This paper describes the application of voice recognition for control of a robotic welding workcell. This is a plex system involving inputs from multiple sensors and control of a wide variety of robot manipulator motions and process variables. While many functions are automated, a human operator serves in a supervisory capacity, ready to override functions when necessary. In the present investigation, a mercially available voice recognition system is being integrated with a robotic welding workcell at NASA Marshall Space Flight Center, which is used as a test bed for evaluation and development of advanced technologies for use in fabrication of the Space Shuttle Main Engine. In the system under development, some functions do not yet have automatic closedloop control, thus requiring continuous monitoring and realtime adjustment by the human operator. Presently, these ovemdes are input to the system through tactile mands (。 許多應(yīng)用語(yǔ)音控制 技術(shù) 還建議 用于太空站 . 一個(gè)主要的應(yīng)用領(lǐng)域?qū)?機(jī)器人 控制功能用于 太空 艙 內(nèi) 檢查、 裝配 、維修、衛(wèi)星回收、維修衛(wèi)星 ,是在船上服務(wù)的監(jiān)督能力和系統(tǒng)運(yùn)作模式的反饋 . 聲音感應(yīng)器和過(guò)程控制的變數(shù)將使船員 影響他 手上的 其它 工作 ,例如直接控制或推翻的操縱議案 。 由于操作過(guò)程中 ,主要監(jiān)測(cè)者必須考慮 在 遠(yuǎn)離的過(guò)程中尋找適當(dāng)?shù)陌粹o或把手 或 靠 像打字員一樣那種打字時(shí)的肌肉記憶。 另一個(gè)因素是可以改善操作 者的 安全 .。 使用語(yǔ)音識(shí)別系統(tǒng)可 以 讓操作者 者 不必再 把 機(jī)器人控制效應(yīng)得指令文件拿在手中，如自動(dòng)控制裝置被使用， 可以改善 操作的 反應(yīng)速度和 運(yùn)行 穩(wěn)定性 。一個(gè)人用手工來(lái)操作焊接時(shí)作出調(diào)整是很容易的，但是機(jī)器人的調(diào)節(jié)靠傳感器的智能和必要的人工操作者的方案調(diào)節(jié)。這個(gè)連續(xù)的語(yǔ)音識(shí)別 系統(tǒng)可以提供多達(dá) 10套，每套有 75— 150句話。機(jī)器人工作單元中的緊急停止電路將會(huì)停止焊接過(guò)程的終止操作者的操作。他們可以通過(guò)貞信號(hào)遠(yuǎn)距離控制。目前焊接機(jī)器人操作的的輸入誤差提和焊接電流已經(jīng)被引入到機(jī)器人程序中。 致謝 在此特別感謝 Martin Marietta 公司的 Mr. Jeff Hudson協(xié)助編作本篇論文。 由于 航空焊接 需要大量人力監(jiān)管過(guò)程實(shí)時(shí)參數(shù) 控制所以 這項(xiàng)技術(shù)已申請(qǐng) 用于 航空
