Factors for selecting a robot based on the application

In an industry, the engineers will be having several robots under their control. According to the job given, the engineers must be able to select the perfect robot. This is only possible, if the engineers are well known about the technical features of every robot.

The important technical features that are to be noted before selecting a robot for an application are:

  • Type of job
  • Configuration
  • Number of axes
  • Drive system
  • Programming method
  • Control system

If the above features of a robot are well suited for the specified application, then the selection will be the perfect for the operation.

For more details, here are some of the applications and technical features required for selecting a robot.

Spot Welding Robot:

  • A robot must be of jointed arm or polar configuration for performing this application.
  • It must have five or six axes.
  • It can have either electric or hydraulic drive system.
  • It must be programmed in powered leadthrough method.
  • It requires a point to point control system.

Spray Painting Robot:

  • For this application, the jointed arm configuration robot will be the appropriate selection.
  • The number of axes must be more than or equal to six.
  • It must have a hydraulic drive system.
  • Manual leadthrough programming method will be required.
  • It must possess a continuous path control system.

Arc Welding Robot:

  • This type of robot can be of Cartesian, jointed arm, or polar configuration.
  • It must be incorporated with five or six axes.
  • It must feature either electric or hydraulic drive system.
  • It is capable of programming with Powered or Manual Leadthrough method.
  • It must have a continuous path control system.

Machine Loading:

  • To perform machine loading, a robot should be of either cylindrical, jointed arm, or polar configuration.
  • It requires only four or five axes.
  • The drive system must be hydraulic for loading heavy weights. Otherwise electric type is enough.
  • The programming method needed for this operation will be powered leadthrough.
  • As this is a simple process, it can have either point to point or limited sequence control system.

Assembly Operation:

  • The configuration of the robot must be Jointed Arm or Cartesian.
  • The number of axes can be from three to six.
  • It requires an electric drive system for this process.
  • It must be capable of programming in textual languages or powered leadthrough method.
  • It must have either continuous path or point to point control system.
