Robot manufacturers claim to have a given accuracy and repeatability. Although, all of these specifications can only work when a proper calibration has been done on the robot. The calibration process for industrial robots is composed of four main steps:
We recently release an article on ''What is a Force-Torque Sensor''. Now that you know what a FT sensor is, we thought that you might be interested in the basics of how these devices work.
The following article is written to clarify the confusion between Ethernet and Ethernet/IP. First, if you do not know what the link, network and application layers of the OSI model are, I suggest you read our earlier blogposts on communication protocol structure and on industrial protocols used in robotics.
On any robotic gripper spec sheet, you will find a measure of the repeatability. What does that term really mean? This blog begins by introducing the repeatability ISO standard used for robot arms, and then explains how gripper repeatability is usually measured in industrial scenarios. As you will see, there is no standard for testing repeatability of robotic grippers, so engineers must ask questions to understand what the repeatability value on a spec sheet really means.
Programming a robotic welding cell has never been easier with our newest How–to video showing Kinetiq Teaching, a new technology to quickly and easily task welding robots without requiring in-depth programming knowledge. This visual approach takes you step by step through the programming of a linear welding path for welding automation.
When watching how the 2-Finger Adaptive Robot Gripper works in the following video you might ask yourself; how this Gripper can be so versatile while using only one actuator? The secret lies in its unique mechanical architecture.

Communication protocols, often called Fieldbus, describe the set of rules to be used in communication between devices. The list of protocols used in today’s industrial robotics is quite large; here is a list of the main protocols and their characteristics.
Communication protocols describe the set of rules to be used in communication exchange; each one having its own syntax, semantics, and synchronization rules. There are currently two main models for communication protocols being used. The Department of Defense (DOD) went in first with the TCP/IP (Transmission Control Protocol and Internet Protocol) suite in 1970 with which the Internet network evolved. Then the International Organization for Standardization (ISO) effort in the networking domain resulted in the OSI model in 1978.
Robotic tool changers are used on robots to change end effectors so one robot can do multiple tasks. It can enable switching between grippers or other end-of-arm tools (such as a finishing tool or welding gun). A robotic tool changer is composed of two sides that are used to standardize the interface between the robot wrist and the different robot tools. This article presents the 5 main problems of using tool changers on a robot to switch between different grippers.

This article presents an overview on how a servo-electric gripper works. The image below shows the main components of an electric gripper and how it interfaces with a robot.
