Medium - technology robots Medium-technology robots are used primarily for picking and placing and for machine loading and unloading.These robots are a bit more sophisticated than the low-technology robots, as the characteristics described next indicate.媒介技术的机器人主要用于拾取和放置机器装卸。这些机器人比低技术的机器人更时髦一点，作为特征表明。
1.Axes.
In the majority of case, the medium-technology robots have a greater number oh axes on the manipulator than the low-technology robots have.These robots also have a large work cell, which mean that axis travel is greater.
1.轴 在大多数情况下，媒介技术的机器人有更多，轴比低技术的机器人机械手。这些机器人也有大量的工作单元，意味着轴行程更大。
The number of axe on these robots is increased because of the addition of a wrist.The wrist connected to the end of the robot’s arm gives the system two or three additional axes.The wrist allows the robot to develop movements that the low-technology robot is not capable of.With the addition of the wrist, these robots may have five or six axes of motion.对这些机器人斧头的数量是因为对手腕的增加。腕关节连接到机器人手臂末端的给出了系统的两个或三个额外的轴。腕关节使机器人发展运动，低技术的机器人是不能够。手腕的加入，这些机器人可能有五或六轴的运动。
The basic medium-technology robot has three axes, or degrees of freedom, as shown in Fig.21-3A.With the addition of a wrist, as illustrated in Fig.21-3B, three additional axes are added to the robot.These axes are called the roll axis, the bend axis, and the yaw(rotational)axis of the wrist.基本培养基技术的机器人有三个轴，或自由度，如fig.21-3a。随着手腕的增加，说明在fig.21-3b，额外的三轴添加到机器人。这些轴为轴，轴的弯曲，和偏航（旋转）的手腕轴。
2.Payload.
Medium-technology robots have a greater payload capacity than the low-technology robots.These robots are capable of handing weights at the end of the wrist ranging from 68 to 150 kilograms.With this increased payload, these robots are able to replace lifting of heavy parts is required.2.有效载荷
媒介技术的机器人有比低技术的机器人更大的有效载荷能力。这些机器人能处理量在手腕的范围从68到150公斤的结束。这增加的负载，这些机器人能代替大部件吊装是必须的。
3.Cycle Time.For a medium-technology robot, a movement in the reach axis of 25 to 65 centimeters takes 1.0 second to execute.In a rotation around the center axis, the robot can move at a rate of 150 centimeters per second.However, these robots will have greater cycle times than the low-technology robots.The complex jobs the medium-technology robots are able to perform and the payload at the wrist flange are responsible for the increased cycle time of the robot\'s operation.3. 周期时间。一个中等技术的机器人，在25轴运动达到65厘米需要1秒来执行。在围绕中心轴旋转，机器人可以在每秒150厘米的速度移动。然而，这些机器人将有比低技术的机器人更大的周期时间。复杂的工作中技术的机器人是能够执行在手腕凸缘的有效载荷是负责增加周期时间的机器人的操作。
4. Accuracy.
Because of the increased number of axes on medium-technology robots, their accuracy and repeatability are not as good as the accuracy and repeatability of low-technology robots.The main reason is that the several axes must converge on a point.The error that is developed because of several axes having to be positioned creates additional error in the accuracy of the robot.Remember that the low-technology robots only move one axis at a time to reach a programmed position.However, the medium-technology robots are capable of repeating their positional data to meet the requirements of the job.
The accuracy of the medium-technology robots can range from as low as 0.2millimeter to as high as 1.3millimeters.These ranges are typical for various medium-technology robots.4.精度.由于对媒介技术的机器人轴数的增加，其准确性和可重复性是不作为的精度和可重复性低技术的机器人一样好。主要原因是多轴必须收敛于一点的。错误，是因为有几个轴被定位造成的附加误差精度的机器人的开发。记住，低技术的机器人只能移动一个轴在同一时间到达一个程序的位置。然而，媒介技术的机器人能够重复他们的位置数据，以满足工作的要求。
对媒介技术机器人精度的范围可以从0.2毫米低到1.3毫米高。这些范围内的各种介质技术的机器人典型。
5. Actuation.
Medium-technology robots are driven by two types motors: hydraulic or electric.These two types of actuation are used because of the heavy payload.5. 驱动.
媒介技术的机器人是由两种类型：液压或电动马达驱动。这两种类型的致动是因为沉重的负荷。
6.Controllers.The controllers found on the medium-technology systems are microproceor-based.That is, the system can have either an 8-bit or a 16-bit microproceor.With the increased power of the proceor, memory size is also increased.Thus, positional data can be programmed into these robots, stored in memory, and recalled for later jobs.
Several jobs can be stored in the controller\'s memory, thus allowing the robots to service two or more machines in the loading and unloading of parts.These robot controllers also allow the user to change or edit program information.6.控制器.在媒介技术系统控制器的微处理器。那是，该系统可以有一个8位或16位的微处理器。随着增加功率的处理器，内存的大小也增加了。因此，位置数据可以被编程到这些机器人，存储在内存中，并为以后工作回顾。
几种工作可以储存在控制器的存储器中，从而使机器人服务两个或两个以上的机器在加载和卸载的部分。这些机器人控制器还允许用户更改或编辑程序的信息。
