Because the position and orientation errors of the robot end-effector are caused by a number of factors such as tolerance in manufacturing and assembly, mechanical transfer errors and so on, this paper analysed the errors of robot by differential method. 由于机械手的加工误差、机械传动误差等诸多因素会导致机械手末端的位置和姿态产生误差,因此本文利用微分法,对机械手的误差进行了分析。
At the linguistic level, faithfulness can be realized at words, sentences and paragraphs. Faithful translation is not a mechanical transfer of word for word, sentence for sentence, or paragraph for paragraph but an accurate translation in the content with flexible methods. 语言层面的忠实应从词、句、段三方面实现,不是机械的字对字、句对句和段对段地翻译,而是应灵活处理,做出适当的调整和改变,从而准确传达原文的意思。
The position and orientation errors of the robot end effector are caused by a number of factors such as tolerances in manufacturing and assembly, mechanical transfer errors and so on. 机器人连杆的加工误差、温度变化以及机械传动误差等诸多因素会导致机器人抓手的位置和姿态产生误差。
Ultrasonic wave has some functions of mechanical mass transfer, heating and cavitation. 超声波具有机械传质、加热和空化作用。
Mechanical mass transfer, heating effect and cavitation effect are physical mechanism. 超声波作用的物理机制主要包括机械传质作用、加热作用和空化作用。
