Hi, I'm a robotics and Al content creator. The videos are quite technical demos and screen recorded tutorials. Although the niece is pretty small, there isn't a lot of crowd, and I've seen channels do well even with a small number of videos (>15)

I had two videos, one which I packaged as quite generic and massy. It got to almost 6.5k impressions with a CTR of just 1%

In my latest video, I was more intentional and packaged so that my core audience will resonate. The CTR for this video was around 10% but youtube didn't push this video at all. Overall I've gotten like less than 200 impressions on this video.

I don't understand why YouTube would do that? Doesn't a good CTR mean that youtube show this to more people?

I am attaching screenshots of both the videos.

I would greatly appreciate any advice or insights if you've seen something before. I would love to understand where I'm going wrong, and try to fix that!

Hey everyone, wanted to share my project on semantic navigation where a robot can explore a simulated living room, remember what it has seen, and later navigate using natural-language object goals instead of coordinates.

For example, after exploration, you can ask it something like:

>

The system retrieves a remembered viewing pose for the object and sends a deterministic Nav2 goal.

Stack used:

• ROS 2 Humble
• Nav2
• SLAM Toolbox
• Ignition Gazebo Fortress
• rosbridge / ROS-MCP
• SQLite + JSON semantic memory
• RGB camera, LiDAR, IMU, odometry in simulation

The idea was to move beyond “go to x, y” navigation and test a more semantic workflow:

1. Robot explores the room
2. Camera observer stores object captures
3. Semantic memory keeps object labels and poses
4. User asks for an object in natural language
5. Robot navigates near the remembered object location using Nav2

It’s still a simulation demo, but I think this kind of object-based navigation is a useful bridge between classical robotics stacks and newer language/vision-based interfaces.

Video demo/tutorial:

Code:

Would love feedback from people working on robot navigation, semantic mapping, or VLM/LLM-based robotics systems. I’m especially curious about better ways to represent the semantic memory and make the object-goal selection more robust.
