What Robot Is Best For My Application?
There are many factors to consider when specifying a robot for an application. What area is my robot in? Does it need to interact with people and in what way? How fast does it need to run? How many axis of movement are needed? What reach is needed? What weight is being lifted/handled by the robot? How accurate does the robot need to be? What comms are needed? Etc.
There are two main categories of robots; collaborative robots which can work with and alongside people, and standard industrial robot which need to be guarded or have safety scanners and systems around them. Both have their advantages and disadvantages but typically collaborative robots are slower, have lower payloads and are more expensive but have the benefit of force monitoring and not needing guarding, while standard industrial robots are fast, accurate and lower price and but do need guarding or safety scanners around them. While collaborative is a big thing at the moment the standard industrial robots are still far more popular for most production lines and manufacturing.
There are several different types of robots:
Probably the most common type of pick and place robot is the robotic arm type; which typically come as 5 axis robots for standard pick and place application in plane, or 6 axis robots for more complex applications where the products needs twisting from the horizontal (similar to the image above).
The cartesian robot is also a very common type of pick and place robot, that used to be cheaper, but is now not so commonly installed apart from for injection moulding machines.
Delta robots are mounted above conveyors and are typically used for high speed pick and place applications.
Fast pick robots are also another option for fast pick and place applications; with cycle times as fast as 150 cycles per minute.
