Dobot Vision Kit, Machine Vision System for Education (STEM) 

Thanks!

Hi, I think this should be possible. Regardless of where the camera is located a calibration is needed. In one of my earlier videos I had a pixy camera mounted to the arm. Also there it was needed to calibrate the camera at the same height as where it would take a snapshot to find parts. You could mount the camera to a post, fixed to your rail carriage so it moves with the arm bit stays at the same height. The other option is at the eend of the arm but then you would need to raise the arm to the same height each time to take a picture to find parts. So the position of the carriage on the rails is not important, but more the height of the camera and it's XY position in relation to the arm. In both cases the XY compared to the arm is the same for each position on the track. Hope this long answer actually answered your question.

Hi, this is difficult for me to answer as I have already sent the unit back and therefore no longer have the USB dongle to run the software. The coaster program was based on functions used in the sample files. It is not completely the same but I only used functions that are also used in the examples provided with the software. If you run those, there is also one with a loop function for finding features. My program has the same type of loop. This is the best I can do at the moment, I hope this helps. Robin

@@uptimefab7412 Thank you for your answer. As you said, I checked the example and found that I used the wrong function. I modified it according to the example, and it worked properly!!! Thanks to you, I learn more. Have a nice day :)

Good to see you were able to resolve the issue. Happy programming!

@@222sseum I am starting to learn the basics of this vision software how to use it. My question is would the user guide of vision studio pdf be enough for me to learn and develop a project myself. Thankyou I would be waiting for your answer

@@222sseum ​ once i finished the colour sorting first time it worked perfectly but then next day when i started to run the same program from beginning dobot started to move to the places where the colour blocks where not even present. Would that be the calibration problem or something else I don’t know what to do could you please help me with that?

Thanks! Maybe openMV is something to have a look at. I have not used that before so I am not sure how it compares to the Dobot Vision system.

Hi! The radius is also converted from the image to real world coordinates, similar to the other examples. I no longer have the system, but a similar example for determining size of circles is included in the product manual, which can be downloaded for free from the dobot website. That should put you on the right track for how this is done. Cheers, Robin

@@uptimefab7412 thank you so much Mr.Robin

Hi, I no longer have the system, just had it for Review. This means I also can't run the software, so helping out with specific programming issues will be difficult. If you have issues with translating the coordinates I would suggest rerunning the calibration procedure, making sure you do it accurately and in the right direction. Also start with a simple example from the manual to see if that works before making your own program. If you still have issues, post the specific question in the don't forum. Sorry this is the best I can do at the moment.

@@uptimefab7412 what was the version you use in the video?

I am not sure which version the software was unfortunately.

Hi, for 2D barcodes the Vision Studio Software that comes with the vision kit can identify QR code and DataMatrix code. (Also a number of 1D barcode formats are supported.) I have not tested 2D barcodes myself, but you can find a detailed description of the capabilities for this in the Dobot Vision Studio User Guide. This can be downloaded for free after creating a free account on dobot-robots.com.

Hi, I also did not have very much in depth knowledge about this type of system before testing this camera. I think by following the PDF guide you will be able to learn the most important functions of this system. You would need to have access to the vision camera and actually do the experiments. Just reading the PDF does not provide enough insight I think.

@@uptimefab7412 Yes mvs vision system camera is provided and i am having access with that. I did the first example today practically choosing green colour thanks Allah and then thanks to you ❤. I took me just two days to accomplish this but do you think within a month or so may be more i will be able to do any more or less complex project using this dobot magician and publish a paper using that. What is your thought on that? Please do reply?

Hi, I think you should be able to create more complex projects after some more experience. I would r commend to create every examen in the software that is explailned in the manual. This will allow you to have knowledge on most functionality. It will take a couple of days to go through all the examples but well worth the effort.

@@uptimefab7412 thankyou ❤️ I will surely try in sha Allah

Hi, I am not involved in selling this type of equipment, but I see that in my country the price is close to 2.000 euro at the moment. Might be different in other countries.

Hi, you can create a flow with a color filter to pick up blue cubes and then just press the continuous run play button from the menu bar. This with loop the program indefinitely.
