1. Cartesian coordinate type
Advantages: This kind of operator has a simple structure, strong intuitive movement, and is easy to achieve high precision.
Disadvantages: It occupies a large space position, and the corresponding working range is smaller.
2. Cylindrical coordinate type
Advantages: Compared with Cartesian coordinate operator, cylindrical coordinate operator not only maintains the advantages of strong intuitive movement, but also has the characteristics of small space, compact structure and large working range.
Disadvantages: Restricted by the lifting mechanism, the workpiece on the ground or in a lower position cannot be lifted in general.
3. Spherical coordinate type
Advantages: Compared to cylindrical coordinate operators, this type of operator occupies the same space, its working range is expanded, and due to its pitching degrees of freedom, it can also extend its arms to the ground to complete the task of extracting the workpiece from the ground.
Disadvantages: poor intuitiveness of movement, complex structure, and the position error of the arm end will be amplified with the elongation of the arm.
4. Joint type
Advantages: The articulated manipulator has certain characteristics of a human arm, it takes up the least space and the largest working range compared to other types of manipulators, in addition to being able to pick up and transport the workpiece around obstacles. Therefore, it has received widespread attention in recent years.
Disadvantages: Less intuitive movement, more complex drive control.
