Pick and Place robot types: the most common configurations

There are a few common Pick and Place robots out there. 

Here are the most commonly used ones: 

Cartesian robots

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

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 mm.

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 mm) 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.

Six-Axis robots

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.

The main difference between Cartesian and other Pick and Place robot types 

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:

• Work envelope and ROM Cartesian robots offer a larger cubic workspace, SCARA robots have a more limited cylindrical area, and Six-Axis robots typically have more versatility and range.
• Payload capacity (aka weight): Cartesian robots can typically handle heavier payloads, up to several hundred kilograms. SCARA robots usually max out at around 10-20 kilograms. as do most Six-Axis robots. 
• Accuracy matters: Cartesian robots can manage a very high degree of precision and repeatability due to their rigid linear structure. SCARA and Six-Axis robots may have slightly lower precision because of the nature of their rotary joints.
• Speed: Cartesian robots are exceptional for high-speed pick and place applications, with some models reaching up to 10 m/s. SCARA and Six-Axis robots typically max out at around 5 meters per second.
• Cost and footprint: SCARA and Six-Axis robots tend to be more affordable and compact. Some of them can even work alongside humans. On the other hand, Cartesian robots leave a larger footprint and require a higher initial investment - oftentimes requiring you to modify your shop floor as well.
