Answer: Not entirely true.
Answer analysis: In robotics, a work range configuration is a way of describing the area of space that a robot can reach and operate.
While the four main work range configurations you mentioned, "rotational, Cartesian, spherical, and open," are not strictly categorized for all robots, I can explain how these concepts relate to the work range of a robot based on the universal characteristics and common types of robotics.
1. Rotational work range:
- Rotational work range is usually associated with robots that have a rotary joint or a rotating base.
For example, many industrial robots include one or more rotational axes that allow the robot to rotate in a horizontal or vertical plane.
The first axis (base rotation axis) in a six-axis industrial robot is a typical rotational axis, and its work range is usually limited to ±360°, allowing the robot to rotate in all directions on the base.
2. Cartesian work range:
- Cartesian robots, also known as rectangular coordinate robots or gantry robots, have a work range defined by movement along three orthogonal axes (X, Y, Z).
This type of robot has a simple structure, is easy to understand and program, and is suitable for tasks that require linear motion. Its working range is usually a three-dimensional rectangular space, which is determined by the robot's travel limit.
3. Spherical working range:
- The spherical working range does not directly correspond to the type of robot in the traditional sense, but it can describe certain robots or manipulators with spherical working spaces.
However, in common industrial robots and manipulators, there is no working range configuration directly named "spherical". However, some robots may be able to cover a spherical space area to a certain extent through the combination of their joint flexibility and working range.
4. Open working range:
- The "open" working range is a relatively vague concept, which may refer to a working area without strict restrictions or with wide flexibility. However, in the terminology of robotics, "open" is not directly used to directly describe the working range.
Instead, it may be more related to the design, application environment, or operational flexibility of the robot. For example, some robots may have a retractable or adjustable arm length, allowing operation in a wider space.
It should be noted that the above classification is not a strict standard, but a summary based on the general characteristics and common usage of robotics.
In practical applications, the robot's work range configuration depends on its design purpose, application scenario, and performance requirements.
In addition, there are other types of work range configurations, such as polar coordinate robots (which define the work range through radial and angular motion) and articulated robots (which cover complex three-dimensional spaces through the coordinated motion of multiple joints).
These different types of robots each have their own unique work range configurations and applicable scenarios.
