A Pick and Place robot is an automated system used to pick up and move objects from point A to point B.
You can commonly see these robots on assembly lines, handling repetitive, headache-inducing tasks.
Some of the most common uses for Pick and Place robots are:
And, no matter the specific type you choose, Pick and Place robots skyrocket productivity, reduce costs, and improve quality and consistency.
Plus, by taking over repetitive manual labor, they also create a safer work environment for employees. We’re talking about repetitive use injuries, serious accidents, and all manner of unwanted occurrences.
And, while the upfront investment in automation may seem high ($2,000 to over $100,000), the long-term benefits to your business could be enormous.
So if you're looking for a way to streamline your assembly or material handling processes, a Pick and Place robot could be just what the doctor ordered.
Luckily, the variety of options and configurations available means there's likely a model well-suited to your needs, and that’s what we’re here to help you with.
There are a few common Pick and Place robots out there.
Here are the most commonly used ones:
These classic Three-Axis robots move along the typical X, Y, and Z axes.
Their game is precise, linear movement, so you’ll often see them in assembly tasks that require pinpoint accuracy.
This type of linear motion can zoom by at high speeds, quickly traveling long distances - even with a heavy payload.
However, their range of motion is rather limited since they can only move in straight lines.
Delta robots, with their distinct spider-like resemblance, have parallelogram-shaped arms that enable swift, high-precision movement. They also possess a wide work envelope, ranging between 500 to 1500mm.
Therefore, these bots excel in quickly maneuvering objects, maintaining an impressive precision level throughout. Moreover, their unique design is great for quick adjustments and placements, enhancing their efficiency in pick and place applications.
However, we have to note that their intricate structure often leads to higher costs and more thorough (read: expensive and time-consuming) integration processes.
Despite these setbacks, advancements in technology are gradually introducing faster options within the realm of Delta robots - and with it the promise of higher speed and performance.
With a Four-Axis design, SCARA (or Selective Compliance Assembly Robot Arm) robots are pretty skillful.
Their large work envelope (sometimes over 1100mm) helps them reach around obstacles. The first two joints allow the arm to extend, retract, and rotate, while the last two joints provide a wrist-like motion for manipulating objects.
SCARA robots excel at high-speed assembly and pick and place applications that require a much wider range of motion.
The most modern of the Pick and Place robot types, Six-Axis or “6DOF” (Degrees Of Freedom) robots have the most flexibility, sometimes even exceeding human arms.
They can rotate and pivot in 360 degrees, which gives them a full range of motion and the ability to grab onto objects from nearly any orientation.
You’ll often see Six-Axis robots in complex assembly tasks, packaging, and loading/unloading operations where items may be in unpredictable positions or orientations.
However, their complex design typically makes them slower and more expensive than other options. Mind you, faster options are becoming increasingly available.
We’ve already gone over the most common types of Pick and Place robots used in manufacturing and assembly processes.
But while they share some superficial similarities, there are a few important differences to bear in mind when determining which one you need to enhance your operations.
Here are the main differences you have to think about:
When choosing a Pick and Place robot for your application, each has its own pros and cons to keep in mind.
Here’s a short list of the main advantages and disadvantages of Pick and Place robot types:
We’ve already established the speed and efficiency of Cartesian Pick and Place bots. However, their rigid movements can limit their versatility, especially if you need more complex movements.

Pros:
Cons:
The complex design of Delta robots typically makes them the most expensive type, but also the fastest for pick and place ops.
Pros:
Cons:
The unmatched flexibility of Six-Axis robots offers an extensive range of motion that surpasses many other robot types.
This versatility allows them to handle complex tasks with multiple orientations and reach points, making them ideal for diverse applications.
