hey, so i am working on a quadruped robot, RosPug by Hiwonder. while working on its simulation part (using ROS noetic and gazebo, as it was primarily used in documentation) my robot is not moving straight in line, either it is constantly circling along an axis or taking a slight curvature in its path, i don't know what could be reason behind it and fix for it.
I have even attached a video for reference.

For the past several months, I've been working on ROS2GO.IO, a platform designed to make learning ROS 2 easier for beginners.

When I first started with ROS 2, I found that many tutorials assumed prior knowledge or skipped important setup steps. Even installing the development environment could be overwhelming for newcomers. I wanted to build something that teaches ROS 2 step by step, with a focus on practical robotics projects instead of just theory.

The project is currently in Early Access, and I'm actively building new lessons and improving the learning experience based on community feedback.

Some of the topics I'm working on include:

• ROS 2 fundamentals
• Topics, Services, and Actions
• Navigation2
• SLAM and Mapping
• Mobile robots
• ESP32 & micro-ROS integration
• Real-world robotics projects

I'm sharing this here because I'd really appreciate feedback from the ROS community.

• What was the hardest part when you first learned ROS 2?
• What kind of tutorials or projects do you wish existed?
• If you were learning today, what would make the experience much easier?

I'd love to hear your thoughts. Thanks!

Hi everyone. I am working to setup an EKF using the robot_localization package.

I use a single EKF setup which fuses data from GPS (using a navsat_transform node) , odometry, and IMU to localize and publish the map -> odom transform.

I do not use a second, local EKF as my robots odometry is used to publish the odometry -> baselink transform.

For the most part, my setup has been working out fine. The issue is that when GPS becomes unreliable and position jumps around, the whole localization falls apart. Navigation with Nav2 becomes impossible and the robot simply rolls in circles as its location jumps around the map.

From my understanding, the EKF is supposed to prevent this kind of situation from occurring since large covariance values from the poor GPS measurements (which typically are >50) should reduce the Kalman gain associated with that sensor, thereby reducing that sensors influence on the next update step. Therefore my robots position should not be so heavily influenced by these jumps as long as the other sources of data are being smooth and reliable.

The EKF fuses the X,Y positions from the robots odometry and GPS odometry given by the navsat_transform node. Ive provided my EKF parameter configuration for reference.

Am I failing to set my parameters correctly? Do I just have a fundamental misunderstanding of the EKF? Is my Nav2 setup potentially the issue?

Any advice helps. Thanks!

hey guys, I have completed my undergrad and unable to get any jobs now i am thinking to learn ros is it any good?? if it is good could you help me with basic tutorials and guides which i can use to learn ros ??

Hi everyone,

I’m based in France and I graduated about a year ago with a Master’s degree in Robotics, focused on robotics software engineering. Since then, I’ve been actively looking for my first full-time role in robotics software, but I’ve been struggling to get hired.

My technical background includes ROS/ROS2, C++, Python, Linux, Gazebo, MoveIt, OpenCV, Docker, simulation, perception, sensor integration, trajectory planning, and robotic system validation.

To stay active and keep improving, I joined robotics associations where I work on projects involving ROS2, autonomous navigation, simulation, robotic integration, and vision. I also started registering on freelance platforms, hoping to find small robotics-related missions or collaborations.

I’m mainly targeting roles such as Robotics Software Engineer, ROS2 Developer, Robotics Integration Engineer, Perception Engineer, Simulation Engineer, or Robotics Application Engineer. I’m open to opportunities in France, Europe, or remote positions.

Here is my portfolio, where I present some of my robotics projects and technical work:
Portfolio: https://portfolio-alain-ngoko.vercel.app/

I would really appreciate advice from people working in robotics or hiring robotics engineers:

• What would you recommend to someone trying to land a first robotics software job?
• Are there companies, startups, labs, or sectors in France/Europe I should target?
• What kind of projects should I improve or showcase more clearly in my portfolio?
• Is freelance realistic for a junior robotics software engineer?
• How can I make my applications stronger and stand out?

Any feedback, company suggestions, portfolio advice, or personal experience would be very helpful.

Thank you in advance.

Hey,

im currently studying mechatronic in my masters and we are doing a project which is not coming forward since 2 Weeks and we only have 1 week left. So if anyone can help us it would literally save our a..

So to the Project. We currently setting up isaac sim for a future project for a neura roboter we will get. The goal of our Project is to import the so101 from lerobot into isaac sim and move the robot in the simulation by moving the real robot. While doing that saving all the joint datas etc. via lerobot in the lerobot format.
We are running isaac sim on a windows os and ros2 in the wsl.
What currently is running:

1. Isaac Sim 5.1 with ros2 in wsl. But using Isaac Sim 6.0 is not working. When we publish some topics they are not seen in the wsl. We dont know why and really tried everything. Is the new automatic Ros2 Bridge in Isaac Sim 6.0 broken? We even tested with the new isaac sim 6.0.1. Still not working.

2. Using ONLY Lerobot to teleoperate the so101 follower with the leader. Works really fine

What is not working fine:

1. If we move the so101 in isaac sim the robot joints are oscillating. Is the urdf incorrect? We did use the urdf from the original github. Do we have to change the physical parameters ? Does smybody know how?

Where we dont know what to do now:
So we habe the so101 in isaac sim. We have ros2 in the wsl. So know we have to create a ros topic which shares all the joint movements and subscribe to that topic inside isaac sim and use the articulation controller to move the robot in the simulation. BUT:

1. How do we connect the so101 to the environment inside wsl?
2. In this setup. How do we add lerobot? How are we using lerobot? Where are we adding lerobot?

If you have any questions feel free to ask us.
We are thankfull for every help

If someone built a simpler, less complex framework type alternative of ROS2 that still doesn't hide things, would ROS 2 devs use it? What exactly would it take to do so? I use ROS2 but sometimes I just hotwire my code directly instead of relying on ROS. I honestly don't know. Sometimes ROS feels lovely but there are times I feel like this shit just didn't exist.

Hi, i am a maker that has built many robots already (mostly with arduino, esp32 and stm32). I wanted to learn ROS and learn about its features, capabilities etc and how to use it with an esp32. i wanted to build a robot that maps a room and then navigates in it or something similar, and my friend reccomended to use ROS for robots. can someone comment a link for decent learning material?

I'm looking for ideas for my graduation project. We're a team of 11 students with a mix of software and hardware backgrounds. Some of us focus on AI, backend development, and software engineering, while others are interested in PCB design, embedded systems, and hardware development.

We're aiming for a project that is innovative, technically challenging, and has a strong real-world impact. Personally, I want to continue in robotics software after graduation, so I'd love to incorporate ROS 2 into the project if possible.

If you have any project suggestions, GitHub repositories, documentation, research papers, or resources that could guide us, I'd be grateful if you could share them.

Thanks in advance!
