  Robotics Software Engineer Intern

  Karelics 09.01.2023 - 10.04.2023

  Developed Docker container in ROS 2 Galactic for code development. Developed ROS 2 Navigation node implementing Smac Hybrid Planner and created a goal validity checker node that checks for goal pose validity and recalculates new valid goal pose if needed. Developed unit tests for goal validity checker node. Developed behavior tree node that implements service node into behavior tree to integrate service into ROS 2 Navigation. Tested proposed solution on the companys robot showing promising results. Link: https://karelics.fi/developing-a-goal-validity-checker-node-for-navigation-goals/

  18.12.2019 - 16.12.2022 Master's in Mechanical Engineering but my Master's Thesis was focused on the software side of robotics. It was about the development of an autonomous mobile manipulator performing a fetch-and-carry task. Here is the GitHub link: https://github.com/jkoubs/Cali-Mobile-Manipulator.git

  Koubot ROS 2 Sensor Fusion - Development of a Mecanum Wheeled Robot using ROS 2

  17.10.2023

  Assembled a mecanum wheeled robot using real hardware components, including a Raspberry Pi 4B as the robot computer, an Arduino Mega, and 2 L298N motor drivers for controlling the 4 wheels. Developed a Docker container for running ROS 2 and ensuring a consistent and isolated environment. Utilized FreeCAD for designing the robot model. Transferred the model into ROS 2 using URDF and Xacro, enabling simulation and visualization within the ROS 2 framework. Implemented mecanum wheel kinematics and dynamics within the ROS 2 ecosystem, demonstrating your understanding of robotic motion control. End goal: Perform sensor fusion combining data from IMU, LiDAR and camera to improve accuracy and reliability in navigation using the ROS 2 navigation stack. Next step: ROS 2 control integration focusing on establishing a connection between ROS 2 and the real robot.

  Multi-Robot Collaboration to Perform a Delivery Mission using ROS 2

  21.02.2022

  Use of two robots, a wheeled robot and an arm manipulator, collaborating together to perform a delivery mission. Developed software in ROS 2 with C++, MoveIt 2, Gazebo and Rviz. The mission involves a set of different steps. First, the wheeled robot drives autonomously un- derneath a cart and attaches to it. A manipulator positioned on a table will pick an object using object detection and place it into the cart. Finally, the cart, now carrying the object, will transport it to a new location. Developed Navigation, Manipulation and Perception pipelines. Developed the same project in ROS with Python and MoveIt.
