The format is the same as in previous chapter and as documented in the Script manual, but since we are not using the teaching pendant we need to send the Script file to the Robot control through an already prepared open port on the Robot which is TCP port In this case we are using the program language Python and the Python environment to communicate with the Robot.
The Script file can still be edited in a Notepad. The first program example is just to illustrate how to send a script file through via the Ethernet to the TCP port on the robot. In this case the robot has already been configured to IP address The first Program 1 just turns digital output number 2 ON and the robot does not move at all and the program looks like this.
The program is run from the host computer and will only have one passage because there is no loop in the program. Then the Script code necessary to connect and send on the Socket.
The Socket connection needs to be closed again with the s. The second Program 2 is similar and just turn digital out number 2 OFF again and the robot does not move at all.
This program send in Script mode via socket port runs through 7 Waypoints. See next page for comments. Same program as above i. Here with comments. In robot Move Screen the jopint positions expressed in degrees i.

I have tested this code with UR10 and it works well. However, now when I try to execute the same code using UR5e, the robot receives the command being sent but vibrates with noise and very slowly moves to the said position. Thereafter, it becomes smooth in motion. Could you please help me with what could it be due to?
Are there some initial setting for the E-seried UR robots that I could be missing upon? Also, another difference that I observed while working with UR10 and UR5e is that when UR5e is put into remote control mode, it is only then that the UR5e respond to the TCP commands and during this the teach pendant interface is disabled except the emergency stop.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

When it comes to adding a robot to production, one of the most challenging parts is often part presentation. Teaching the UR to go to a specific place and pick up a part is a breeze, but finding a cost-effective way to get that part into a repeatable position can often be the challenge.
You have many different options when it comes to part presentation. You can set up a magazine, you can have an operator load a fixture, and even have an operator stage multiple parts into a fixture that the robot can pick from. The downfall to these is that it often still requires at least some amount of operator involvement to keep enough parts in the system for the robot to function. If your parts lend themselves well to stacking, this may be your best option. To fixture a stack of parts into repeatable position can be much easier than creating multiple nests, or designing a magazine feed system.
This would, in turn, create more operator involvement because they would not only need to load the stack, but they would have to take the time to count the parts and make sure they have the correct amount. Fortunately, Universal Robots has you covered. In the following example, I will be picking from a stack of parts and utilizing a part presence sensor incorporated into my end of arm tooling to locate the top of the stack.
This will be the starting point for our robot program.
As you can see in the image below, we have added our home position as well as an approach position for the stack. This will add the Seek template into our program. Next, we need to select the Destacking option as we want to de-stack parts for the next stages in the process.
A very similar and intuitive process would be carried out if you wanted to stack parts once your process has been completed.
The next step is to set up our condition. Then, click into the dialogue box to create the condition you will be looking for.
This will vary a bit for your application depending on how you wired in your sensor. Once complete, click submit to store the condition. Once you submit your condition, you will need to input your item thickness here. This will be used in the background of your robot program to help speed up the seek process. Once an item has been picked, the robot will quickly move to the next anticipated stack position before beginning the seek function.
The next part of the programming will involve teaching three waypoints. The start position waypoint noted by orange arrow will be the position from which the robot will begin the seek function. The from position and to position will dictate the direction of travel that will occur during the seek. Our recommendation is to teach the from position as the highest possible point for the stack, and teach the to position as the bottom part in the stack.
You will need to check the box to select this method highlighted by the blue arrow. Stack position one will be the first anticipated pick location of your stack, however if the stack presented is lower than what is taught, the robot will seek until it finds the first part. So when teaching the exit point, move high enough or in the correct direction to clear any fixturing you have put in place for the stack. The exit point will then be translated to each subsequent pick within the stack.
Once this is complete, you will need to set your gripper command to actuate the gripper. In this case, We are using a Robotiq gripper, so we have inserted the command to close that gripper. At this point, you have completed the de-stacking template. From here, we now need to tell the robot what to do with the part that we have picked from our stack. As you can see beside the orange arrow, my next move command is no longer within the hierarchy of the de-stack template.
This is very important because at this point, we no longer want the path we create to be relative to the de-stacking template.Note that older or newer software versions may behave differently. A loop is a sequence of commands that are repeated until something occurs to stop the loop such as the program being stopped. Using the program in Figure 1 if the checkbox is deselected, as seen, the program will stop after Waypoint 5, if the checkbox is selected then the program will continue to run until stopped by some external force such as an operator tapping the Stop Button.
The Loop command has 3 types of logic that can be used to determine how it will act seen in Figure 2. The 3 options are: 1 Loop always, 2 Loop X times, and 3 Loop as long as the following expression is true.
To use a loop in a program you can either start with one if you know for a section of your program you want it to loop or you can modify existing code by adding a loop and moving the commands into under the loop. Then move the commands that you want into the loop structure, as seen in Figure 5. With the above loop command in place Waypoints 4 and 5 will repeat 2 times before the loop command ends and the program loops back up to the start of the program.

Like any other programming language, UR Script has variables, types, flow of control statements, function etc. Additionally, it is possible to execute programs on the robot from RoboDK if the robot is connected to the computer.
It is also possible to transfer program files through FTP. The robot must be connected to the computer through an Ethernet connection direct connection or through a network. A Ping test allows testing if the Network link has properly been stablished. Robot drivers provide an alternative to Offline Programming where a program is generated, then, transferred to the robot and executed. More information available in the Robot Drivers section. There should be a green message displaying Ready if the connection succeeded.
The robot can be moved by selecting Get robot jointsMove Joints and Move Linear, from the connection menu. There are two different methods to run the program from the PC to the robot:. This method is useful for debugging purposes.
Right click the program Print3D in this example. Double click the program to start it or right click and select Run. Once this option is checked it will connect to the real robot every time we double click a program or right click, then, select Run. These operations are also available from the RoboDK API and it allows integrating robot programming with other applications. Send program to robot generates the complete program, transfers it to the robot and starts the program on the real robot Robot Offline Programming :.
There is a macro available in the library that allows monitoring the state of a UR robot. A new Python object will we added in the station. Make sure the IP of the robot is properly provided in the robot connection parameters. The simulator will update the position of the robot and will create targets as the real robot is moved.
Among other things, it is possible to monitor the robot speed, acceleration and motor currents. These two files can be executed by the robot controller.
