Determining which industrial robot will suit your business is a crucial decision to make before actually buying one. However, during the early stages of industrial robot buying process, you need to decide on a number of factors. Knowing about the size of the 
robot, payload capacity, reach, repeatability and other specifications will play a vital role in helping you buy the right industrial robot for your business.
Here are some common specifications that you should always look for before buying an industrial robot:
Size of the Robot
The physical dimensions and weight of an industrial robot need to be considered before you make a purchase. This will help you ensure that the robot will fit in your existing systems and equipment that are already a part of your manufacturing process.
Maximum Payload Capacity
The payload capacity of robots is measured in kilograms. When buying the robot, there’s no way you can ignore this characteristic. The size and weight of the robot and its parts need to be considered in order to ensure that it is able to perform the required operations. In addition to this, you must also pay attention to the weight of the end of the arm tooling, also known as end-effectors.
Repeatability
Repeatability refers to the ability of the robot to return to a previous point. A number of industrial robots feature repeat abilities of +/- 0.5 millimeters to +/- 0.02 millimeters. The size of the robot, axes and reach of the robot are factors that affect repeatability.
Horizontal and Vertical Reach
Reach capabilities are an essential aspect that you should consider when buying a robot. They help in deciding whether the robot is accurate for your manufacturing process or not. The robot needs to be able to reach the necessary areas of the part or system it is working on.
Number of Axes
There are usually six axes in a robot; however, not all of them are manufactured with six axes. Axes speeds have a huge impact on the cycle times, thus they should always be considered. Based on your operations and manufacturing processes, make sure that the robot you’re purchasing has the essential axes of motion.
Another essential aspect that you shouldn’t ignore when purchasing a robot is the manufacturer. Make sure that you purchase robots from manufacturers ABB, Fanuc, Motoman, KUKA, Kawasaki and Scara.
