Why Should You Choose a 6-Axis Industrial Robotic Arm?

Since the 1960s, the use of robotics has exponentially risen. Back then, robots were primarily used in the automotive industry for assembly, painting and welding applications. However, the use of robots has spread to new applications and industries all thanks to advancements in electronics, artificial intelligence, technology and computing components such as sensors and end-effectors.

At present, robots are a growing presence in plenty of applications ranging from agriculture, electrical and aerospace industries to material, warehouse and food and beverage technologies. It is such advancements that have contributed to robots becoming easier to use, safer to program and affordable leading to an increas4 in their demand.

A fundamental part of industrial robotics is formed by the robotic arm. A variety of different tasks can be performed with tools mounted onto the industrial robotic arm. Several types of robotic arms exist and are currently being used in a wide array of industrial applications. They include the polar, cartesian, articulated and cylindrical robotic arms.

What is a 6-Axis robotic arm?

Industrial robots have a variety of axis configurations but they normally range between one and six. However, the vast majority of articulated robots feature six axes also known as six degrees of freedom. A six-axis robotic arm is capable of rotating freely in circular motion to manipulate parts and position end-effectors. This type of robotic arm can usually rotate more than 360 degrees in either an anticlockwise or clockwise direction.

Main characteristics of a 6-axis robotic arm

With any given orientation, a 6-axis robotic arm is capable of reaching any point in its area making it optimal for a plethora of tasks. Some of them include:

  • Opening a drawer, grabbing an object and closing the drawer
  • Writing text on a wall, desk, or any other surface
  • Getting a tool such as a screwdriver from the bottom , turning it around and placing it back

There are often two ways of controlling a 6-axis industrial robotic arm. You can either use pose target which entails translation (x, y, z,) and rotation (x, y, z) from the robot’s origin or give the angle for each of the six joints.

Can a 6-axis robotic arm be used in all applications?

No, because there are some cases where this type of robotic arm can be a total overkill solution. A simpler industrial robotic arm is best suited for very specific application requiring precision but no complex movement.

When should you choose a 6-axis robotic arm?

Choosing a 6-axis industrial robotic arm ideally depends on what you want to achieve as well as your application. First and foremost, you need to know exactly what tasks you want the robotic arm to carry out. It can be:

  • To press buttons on a machine or load and unload
  • To interacts with human colleagues, give them some tools or hold objects before they are placed in a box
  • To pick and place objects

 If any of these is what you need done, then a 6-axis robotic arm is the right fit. However, you might need to get a few more industrial robotic arms if you are in any of the following situations:

  • If your application doesn’t involve just one single task such as cutting wood on a table and it would be too difficult to integrate a variety of different machines
  • If your application involves complex movements
  • If you want to be able to program and reprogram the industrial robotic arm so that you can use it for a variety of different tasks

Remember, a 6-axis robot can not only perform a wider variety of applications compared to robots with fewer axes but also allows for greater flexibility.

We all know how expensive it can be to purchase an industrial robotic arm. However, with emerging trends in the world of robotics, it is now easier to get one. In fact, new-age industrial robotic arms are not only perfect for education and professional training but their prices will not explode your budget.
