Classification robots
Robots can be classified by their main axis. Furthermore the kinematic defines also the workspace. The following compilation should give you an overview:
| Name | Main axis, workspace | Figure |
|---|---|---|
| PPP, Linear robot, Cartesian robot |  PPP robot |  PPP-Kinematikcs symbol |
 Cartesian robot |  Cartesian or Linear robot - Kinematics and Workspace | |
| Due to the mechanical stiffness of the L(linear)-axes gantry robot are well suited for transport tasks over long distances. In addition, since the floor area is free. Metrologically translational axes are easier to handle than rotary axes. Thats why t-axis can be very accurately positioned. Applications of this robot therefore are: SMD-assembling machines, loading and unloading robots, etc. | ||
| RPP robot |  |  RPP robot |
| Here two translational axes are following the rotational axis. The first T-axis determines the height of the working area, the second T-axis determines the range of the effektor. The advantage is the relatively large range and the high speed at which the robot can rotate around its own axis. These robots are used mainly for loading and unloading workpieces on machines. | ||
| RRP |  |  |
| This robot can also work "overhead". If the third linear axle is realised as a telescope, this robot has a large range. This robot is often used for point and simple arc welding. | ||
| RRP proper name: SCARA (Selectice Compliance Assembly Robot Arm) |  SCARA - Workspace and Kinematics |  Scara Robot |
| Due to its rotational axes of the robot is able to swivel rapidly to the side. Mechanically stable in the vertical direction the joines can be provid high forces. These robots are often applied to assembly tasks. | ||
| RRR proper name: articulated robot or Universal robot |  Articulated Robot - Kinematics and workspace |  3R or RRR - robot |
| With three rotational axes of the robot has maximum flexibility, can operate over head and even complex paths can be driven. Application for this robot are for example complex assembly tasks, arc welding, etc. | ||
| Delta-robot | Simple mounting and pick-and-place | |
