Almost every industry is interested in robots and what benefits they can bring to the company. There are varieties of robots and choosing one that fits your requirements is very important. If you ask any layman what a robot is, they will probably tell you it is a human-like machine that is programmed to perform like a human.
To a business owner looking to improve production and grow their business, a robot is synonymous with productivity and higher profit margins. Robots are classified according to their applications.
Each type of industrial robot has particular characteristics that render it best suited for specific applications. The main elements to consider include the workspace, speed and size. It would not do to have an industrial robotic arm that is not meant for the application you purchased your bot for. It is important to understand the various types to choose well.
Five Types of Industrial Robots
Here are five different types of industrial robots that you are likely to find as you shop around.
Many industries use this one for most of their industrial applications due to the ease of programming and using them. Also, they have linear movements that give the robots a workspace which is appropriate for pick and place tasks.
Additionally, these robots are popular because they can be customised easily to suit the needs of individual customers. The buyer determines aspects such as stroke length, precision and speed since they get a good number of the parts separately. The parts are assembled by the manufacturer because assembly can be quite complex.
Pros of this type of robot include flexibility in their configuration. This makes it easy for them to complete their specific applications with ease.
These resemble the Cartesian robots in terms of axis of motion. Cylindrical robots are quite simple. They are made of two moving elements:
- Linear actuators
- Rotary actuators
They are preferred by machine designers who appreciate their economy of space. This comes with their cylindrical shape. Once the bot is placed in the center of the workspace, it is able to work anywhere around it since it rotates.
The SCARA robot is an all-in-one bot which provides a more complete solution than either the Cartesian or Cylindrical robots. The work envelop is just like that of the Cylindrical robot with more degrees of motion in a radius.
Applications are also similar to the aforementioned robots with one extra detail; the SCARA robot moves faster. The work area is rather small; therefore, this robot is best suited for Biomed applications.
SCARA robots have the easiest integration. As a result, they are hailed as the best solution for most applications. However, Cartesians are more popular because their level of customization is higher.
Also an all-in-one bot, the 6-Axis robots are usually very large. However, sometimes they can be as small as a toy. They operate like a human arm and can pick objects and move them about. This is something that other types of robots may not be able to do easily.
Their programming is more complex than that of SCARA bots. They may be preferred for their ability to make movements that other robots are not able to. This compensates for the lack of space.
These ones are not only the fastest robots; they are also the most expensive. They are also unique in their work envelop as it is shaped like a dome. Within this space, they are able to reach very high speeds.
They are loved for their fast pick and place applications. They are not as simple to use as the SCARA and 6-Axis robots. The main benefit you will enjoy with this robot is speed and precision.
The Best Fit
When choosing the best robot for your specific application you will need to consider the following points:
- Duty cycle
- Work envelop
These factors will lead you to choose the best robot type that will give you the results you envision for your company or manufacturing plant.
The best type of robot will lead to increased production as it will be easy to integrate. In addition, the applications it will undertake are precisely designed for its type.
