The cost of a robotic arm is also influenced by the technology used in the arm, the number of axes it has, and its level of accuracy and precision. The simplest type of robotic arm is a single-axis robot. These arms only move in one direction and are used for very basic tasks such as pick and place operations.

An Industrial robotic arm is controlled using both hardware and software. It moves thanks to motors, like electric servo motors or hydraulic/pneumatic actuators. The robot controller sends signals to these motors, telling the arm how to move and where to go.
