How Can an Industrial Robot Be Calibrated?

Posted by Ahmed Joubair, Eng. Ph.D. on Nov 16, 2014 7:14:00 AM

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:

What is the difference between Ethernet/IP and TCP/IP?

Posted by Nicolas Lauzier on Feb 8, 2014 8:44:00 PM

When it comes to the industrial protocols that we support here at Robotiq, one of the most frequent questions that gets asked is certainly: what is the difference between Ethernet/IP and TCP/IP? Indeed, for a person unfamiliar with this subject, this can be quite confusing. In our daily lives, when we connect a PC to a network, we need to plug a cable into an ethernet card. However, to access the web, we have to configure our TCP/IP settings. And what does IP stands for again? Well, good question because the answer is: it depends! Let's take a few minutes to demystify all of this.

How to Verify Gripper Contact

Posted by Nicolas Lauzier on May 28, 2012 8:00:00 AM

Both of our Adaptive Grippers are able to grip objects of various shapes using their innovative finger mechanism. This allows for firm grips of various objects without the need to build custom grippers for each application. In addition to this adaptability, the Gripper is able to determine when it has gripped an object. This is useful to determine if the pick-up procedure was performed correctly and if the robot can move to the next step of its program. In some cases, however, it is also useful to verify if the Gripper still has the object after a motion is executed by the robot. For example, if the object position was not initially determined accurately (for instance, if the object has moved or if the vision system had a problem), it is possible that the object could be picked up in an awkward position. In this situation, the object might slip out of the Gripper if the robot moves very rapidly to its next position. Knowing that the object was dropped is crucial for many applications. So below, I will explain the appropriate procedure to verify if the Adaptive Gripper still has the object after a robot motion.

How the object is detected during the grip

When a command is sent to close the fingers of the Gripper, the motor moves towards a target position. If the motion is stopped because the Gripper has found an object, the force applied by the fingers will increase until the current sent to the motor exceeds its limit (which is fixed using the force parameter). At that moment, the motor will stop moving and the grip force will be maintained by the Gripper's auto-locking mechanism. By reading the motor position, the Gripper is able to determine if an object was gripped or if the motion was stopped due to the fingers touching themselves. However, from that moment, the Gripper will consider that the object is gripped and will not detect an object loss unless the procedure explained in the next section is executed.

How to Control the 2-Finger Adaptive Robot Gripper?

Posted by Nicolas Lauzier on May 21, 2012 2:02:00 PM

As explained in a previous article, the 2-Finger Adaptive Robot Gripper is able to achieve both pinching and encompassing grips by automatically conforming to the shape of the object. The Gripper is therefore simply programmed using straightforward open/close commands (everything else is taken care by the Gripper controller and the patent pending finger mechanism). In today's article, we'll take a look at how the Gripper can be controlled: how to communicate with it, how to perform simple actions, how to adapt its behavior and how to test the different commands.
