Standard articulated robots consist of six axes. They are available on the market in a large variety of types and variants. Characterized by a cyhndrical working area occupying a relatively small volume, articulated robots easily allow failures to be repaired directly. Articulated robots are used primarily for spot welding, material handling, and painting as well as machining.

Anthropomorphic Robots The anthropomorphic robot, also called articulated robot, is the dominating class of industrial robots. Its kinematic structure comes close to that of the human arm therefore, it is also the robot class that offers the best dexterity and the most humanlike behavior. The arm and the wrist consist of a serial chain of links with rotational joints. This presents a more complex control challenge, but today s large capacity microcomputers have reduced this challenge to a manageable level. There are several variations of the kinematic structure for the wrist, while the three inner arm links normally are configured in the same way for all robots in this class. 

An industrial robot is a computer-controlled, reprogrammable, and multipurpose unit that can move in three or more directions. This is similar to length, width, and height. Imagine the movements your arm would go through if you wanted to touch each corner of your desk. Most industrial robots are basic arm robots. The technical name for this type of robot is an articulated robot (Figure 17-11). An articulated robot has two or more... 

An articulated robot is a robot that has two or more joints that swivel. 

There are two robots. The Scorbot ER-Vn (SC7) is a six DOF vertically articulated robot whose mission is to supply parts to the workstations from the conveyor belt. It is mounted on a linear sliding basis, which grants the robot access to both machine-tools. The Scorbot ER-V (SC5) is also a six DOF vertically articulated robot whose supply parts to the conveyor belt and relocate parts once they are finished. Both robots are operated by external controllers (Cl and C2)... 

Injection-molded polycarbonate sheet for car windows requires injection molding thin-wall large panes up to 11 ft with minimum molded-in stress. They can be injection-compression-molded, with overmolded frames, and removed by a press-mounted six-axis articulating robot [11].

Given their versatility for positioning and the high level of their 3D capability, industrial robots are suitable for automated placement of electronic components on three-dimensional interconnect devices. Six-axis multiple-articulation robots are eminently suitable for placing components on complex, class 3 MID structures with three-dimensional regular or freeform process surfaces.

In the first paper, an approximate path planning algorithm first navigates a point robot in polygonal terrains and returns paths with suboptimal lengths. An innovative four-step trajectory planning algorithm is developed in the second paper for a 3-axis articulated robot in which precise joint-level control can be easily achieved, major mechanical vibration can be avoided, and a well tuned speed can be used to maintain the efficiency. Inverse and forward kinematics for the Stewart Platform-based Manipulator are presented in the third paper. 

This method is based on the 3-axes articulated robot. The reason to simplify the structure of a 6-axes articulated robot into a 3-axes is that the first three axes dominate the dynamic behavior of the entire robot. The last three axes can be easily added to this configuration to reach the desired orientation. Figure 1 shows its configuration and the arbitrary path.
