In contrast with OSI, the TCP/IP community did not spend a lot of effort defining a detailed reference model; in fact, the goals of the Internet architecture were only documented after TCP/IP reference model had been deployed...
Our reference model is divided into five layers, as shown in the figure below. Starting from the bottom, the first layer is the Physical layer. Two communicating devices are linked through a physical medium. This physical medium...
Because of the technical and economic problems discussed above, the typical arc-welding application for a robot is one in which the quantities of production are medium or high. In these cases, a robot cell can be justified which...
Because of the hazards for human workers in continuous arc welding, it is logical to consider industrial robots for the process. However, there are significant technical and economic problems encountered in applying robots to arc...
These applications are material-handling operations in which the robot is used to service a production machine by transferring parts to and/or from the machine. There are three cases that fit into this application...
In planning an application in which the robot will be used to transfer parts, load a machine, or other similar operation, there are several considerations that must be reviewed. Most of these considerations have been discussed in...
Some robot applications have requirements for which a digital computer is the most appropriate method of workcell controller. The reference of the use of a stand-alone computer is used here (generally a minicomputer or...
There are several other issues that must be considered in the design of the workcell. Among these considerations are the following: Changes to other equipment in the cell To implement the workcell and interface the robot to the...
Robot workcells can be organized into various arrangements or layouts. These layouts can be classified into three basic type: Robot-centered cell In-line robot cell Mobile robot cell The following subsections describe these...
