1 Basic Components of Robot Arms
1.1 BASIC ARM TYPES
The identification of the various kinematic arrangements used in industrial robots is useful for manufacturers, users, and researchers. The working volume and dexterity, for example, of a robot are determined by the kinematic arrangements. From the user's point of view, a preliminary determination of the performance of a robot in the work environment based solely on geometry is possible by examination of the linkage type forming the structure of the robot.
Manipulators are typically located relative to ground by either a fixed base or a moving base. The first three links of the manipulator collectively form the manipulator arm. This arm is used for global positioning of the end of the manipulator within the work envelope. The hand is composed of the other links (up to three) and is used to define the orientation of the end of the manipulator. The hand also provides fine local positioning of the end of the manipulator. Detailed treatment of the hands and grippers used in manipulators can be found in Chapter 2. The present chapter discusses various arm types and other components of robot setups.
Two of the three types of connecting elements with one degree of freedom that can be used for connecting links in a robot are the prismatic and revolute pairs. The prismatic or sliding pair allows pure translation of one link with respect to another. The revolute or rotation pair provides pure rotation of one link on another.
The structural arrangement of robot linkage systems (Figure 1.1) includes:

- Parallel connection arrangements
- Multisegmented serpentine designs
Serial link robots (Figures 1.2 to 1.9) may be classified according to type and sequence of the kinematic arrangements of links with prismatic (P) and revolute (R) joints in four main categories:
- Cartesian (P1P2P3)
- Cylindrical (R3P2P3)
- Spherical (R1R2P3)
- Anthropomorphic (R1R2R3)
A cartesian robot, which is also called rectangular or rectilinear, has three translation joints. It generates a rectangular workspace with the three basic motions: base travel (P1), reach (P2) and elevation (P3). Some typical industrial robots of this classification are:
