The visual sensing systems are more sophisticated and are usually based on television cameras or laser beam scanners. The signals of the cameras are preprocessed in hardware and can be fed at rate of 30 or 60 frames per second into a computer. The computer analyzes the data and extracts the required information, such as the presence, identity, position, and orientation of an object to be manipulated, or part integrity and completeness of products under inspection.
An acoustic sensor senses acoustic waves and interprets them. The level of sophistication of acoustic sensors varies from a primitive detection of the presence of acoustic waves to recognition of isolated words in continuous human speech. In addition to human-robot voice communication, acoustic sensing can be utilized by robots to assist in controlling arc welding, to stop the motion of a robot when aloud crash is sensed , to predict a mechanical breakage about to happen, and to inspect objects for internal defects.
Finally there is a class of noncontact systems that uses a projector plus an imaging device to obtain surface shape information or range information.
There are two basic methods of using sensors: static sensing and closed-loop sensing. Frequently, sensors are used in robot systems in a mode wherein sensing and manipulation alternate .That is, the manipulator is stationary while sensing is being done, then motion is done without further reference to the sensors. This method is referred to as static sensing. With this method, the vision is used to establish the position and orientation of an object to be grasped, then the robot moves blindly to the spot.

视觉传感系统更加复杂，通常是基于电视摄像机或激光扫描仪来完成的。摄像机的信号在硬盘中进行预处理，并以30或60帧每秒的速度反馈到计算机。计算机分析数据并提取需要的信息，如测量者、被测物、位置、被测物的某个面或被测产品的部件完整性。
声学传感器能感应声波并解释声波。声学传感器复杂多样，从现场声波的简单侦测到在连续语句中识别单字，复杂性不同。除了人类与机器人的语音通信，声学感应可应用于机器人辅助控制电弧焊，当检测到剧烈的撞击声时让机器人停止动作，亦可用于预测即将发生的机械损伤，或检测物体是否有内部缺陷。
最后还有一类非接触式系统，使用一台投影机加上一个成像设备，以获得表面形状信息或范围信息。
有两种基本的方法使用传感器：静态检测和闭环检测。
通常，传感器在机器人系统中的应用是以检测和操作相互交替的方式体现的。也就是说，正在做检测时，机械手是固定的，然后机械手再工作，而此时传感器停止检测。这种方法被称为静态检测。使用这种方法，视觉是用来建立被加工物的位置和方位，然后移动机器人到现场进行盲目加工。
