Real-time UR10e following a tracked object

Image
For a first trial, it was developed this demonstration of a real-time followed object that is being tracked using one RGB-D camera (Intel RealSense D435).   As seen in this previous post , ViSP is used to process the images acquired by the RealSense RGB-D camera and to continuously track the object . A TCP/IP Socket Connection is established (inside the same computer) between ViSP and ROS . This socket communication is responsible for bringing the geometric transformation between the camera and the object to the ROS environment. This previous post describes with more detailed information this connection. Besides the transformation between the camera and the object, it is also required to know the transformation between the robot and the camera . For the robot to understand the position and orientation of the object in reference to the robot himself, this transformation becomes crucial. For getting it, I performed a manual calibration , as described in this previous post . Fina...

Project Structure - main architecture

Image
Contextualization This project aims to relieve human operators of repetitive work that causes multiple back injuries for the workers, by replacing one person for a collaborative robot. At the moment, the task in hand requires two human operators to: lift a relatively large board (one person on each side)  Check that side of the board Turn the board around Check that other side of the board If both sides are approved, place the board on the automatic treadmill For this, it will be developed a ROS based project, working with a Universal Robot 10 e-series. The workflow of this project is detailed right below. Structure For future development purposes, this task will be built in a modular way, where each step can occur independently of the other steps. This way, it will be possible to start from a simple and fully working job and only then develop and implement more advanced tools that will contribute for the robustness of the project.  The proposed workflow main structu...

TCP/IP connection: UR10e - External PC

Image
To use any of the features that have been published on my recent posts (UR10e external control, gripper external control, etc), it is required to have the cobot connected to my external computer.  For that an Ethernet cable is connected from the UR10e controller to my PC, using a TCP/IP communication protocol.  For enabling that communication, On UR10e Teach Pendant : Click on Menu (top right corner) + System + Network Configure: Network method : Static Address IP address: 192.168.56.2 Subnet mask: 255.255.255.0 Default gateway: 192.168.56.2   Click on Apply   Disable EtherNet/IP fieldbus: Installation > Fieldbus > EtherNet/IP > Disable   On External Computer :       After you connect the cable, you need to configure the IPv4 like this:
