Object tracking robot using ROS Moveit and OpenCV | Arduino

In this video I will explain how to make a manipulator track a coloured object using OpenCV and ROS Moveit.
For better understanding watch my previous video on 3-DOF planar manipulator project.

This was pretty informative, it'll help me a ton in my current openCV project! Thanks!

Great work bro! Really appreciate all the work you post on this channel. Hattsofff

[@deepskills4706]

great, your efforts are commendable. thanks

[@viswadeepkopalli6160]

Great video as always, as a fellow ROS user i found vscode to be very handy with ros and as an IDE we can install RoS extension and voila we can even run ros commands in the terminal give it a try if you are not already using it.

useful info. thanks

sir please tell me about wich camra u have used ?

Hello Sir,
Currently I am working on making Swarm Robots. And main problem I am facing is at starting the robots would be randomly arranged and if I want to implement a circle I would set robot 1 to move from initial xy pos to next xy pos. Now how is it possible with opencv ?
If you cant extend some help it would be very grateful. Tho a very nice video.
Thanks.

unable to locate serial_node.py in your source code. where to find it?

[@hasibrahman1360]

how to start this project ? any schematics diagram? components list requirement . I am really exited to do this great project with ros.

what if we need 3d image?

I am a beginner so can you please tell me how did you run python 3 script on ROS as it only supports python 2

[@roboticsandroslearning8232]

Follow below solution to run python 3 ros scripts.

Hi, it is great work
what is the version of python and opencv you use? I'm trying to run the python scripts and it shows me some errors

[@roboticsandroslearning8232]

Python: 2.7.12
Open CV: 3.3.1

[@MoneeraBanjar]

I have the same versions, but I got this error
OpenCV Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/highgui/src/window.cpp, line 331
Traceback (most recent call last):

cv2.error: /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/highgui/src/window.cpp:331: error: (-215) size.width>0 && size.height>0 in function imshow
I searched for it and they said it related to the opencv version and I should upgrade to 3.4
I'm using ROS kinetic

[@bilawalmehmood8423]

sir which camra u have used ?

[@roboticsandroslearning8232]

This is a normal desktop usb camera. I have shown the camera too in this video.

[@nishantsharma4465]

can you please suggest a book to study these topics in more details , And thanks for making this video

[@roboticsandroslearning8232]

Go through "Mastering ROS for Robotics Programming" by Lentin Joseph.
