Hi everyone!

I'm L Venkata Subramanyam (Venkat), an engineering student from Gujarat, India, pursuing a minor in Robotics.
My technical background: Intermediate robotics developer with experience in ROS 2, SLAM, and computer vision
My robot is about (plan):
I plan to build the Real-Time CAD Extruder: an autonomous rover that drives around a room, building a live 3D structural mesh of the environment in a web browser as it moves. This is an embodied 3D modeling tool where the RDK X5 AI chip processes depth and geometry in real-time, and ROS 2 translates it into an extruded 3D mesh, basically the physical, driving version of a hand-gesture modeling tool.
Excited to join the challenge and learn with you all!

Thank you Lisa & Yujia for helping me get the board.
Just got it into my hands...

@RDK-Moss
How can I connect my x5 with my laptop, I dont have monitor.
I tried connecting x5 with my friends monitor, it worked ... how can i connect with my PC now... gimme detailed steps.

[vintage4681]

@RDK-Moss So see i need to connect x5 with my PC, but i dont have.monitor, but i can get one temporarily. How can I.connect both?
Bruh I dont have ethernet cable...

Great work! Please make sure your GitHub repo is set to Public for review, and we encourage you to start Stage 2 as early as possible.

[vintage4681]

Hey guys @Shockley , drafting up my architecture to knock out Stage 3. I have two quick questions to make sure I don't waste time building something the board can't handle:

1. General BPU Hardware Limits: Ignoring the official model zoo for a second, what is the actual, physical ceiling of the Sunrise 5 BPU? In general, what is the heaviest model architecture you (or anyone) have actually managed to run on this chip before the RAM taps out or it crashes? I just want to know where the hardware's absolute breaking point is.

2. Architecture Check: Dual-Model RGB-D Point Cloud
To complete the multi-task requirement, here is the pipeline I'm planning to build:

Task 1 (BPU): YOLO-Seg to extract pixel-perfect 2D contours.

Task 2 (BPU): FCRN or FastDepth to generate a real-time depth map.

Task 3 (CPU): Take the YOLO mask, cross-reference it with the depth map, and stitch them together to output a local 3D .obj point cloud.

Does this dual-pipeline make sense for the RDK X5 to process smoothly, or is there a simpler/better combo to get Stage 3 checked off?

[vintage4681]

hi guys
the website:
https://d-robotics.g...40pin_define.md
is not working
with "Page Not Found
We could not find what you were looking for.

Please contact the owner of the site that linked you to the original URL and let them know their link is broken."
i went to that link from "https://d-robotics.g...3.5.0&p=RDK X5" s GPIO Interface section.
Thanks

[vintage4681]

Also i made the repo public, please have a look at it whenever you have time.
Thanks

[drobo_community]

Noted, thanks for your report!

[shockley6668]

Yep, your pipeline makes sense.

YOLOv5-Seg 640×640 can reach around 126.64 FPS on RDK X5, so segmentation should not be the main bottleneck. The heavier part will likely be depth generation and CPU-side point cloud / OBJ processing.

For Stage 3, I'd suggest starting with:

YOLO-Seg -> object mask
Stereo depth -> depth map
CPU -> mask × depth -> local point cloud / OBJ

This should be simpler and more reliable than starting with FCRN/FastDepth. If you still want to try FCRN/FastDepth, you may need to export the model to ONNX and quantize it with the D-Robotics toolchain.

Quantization guide:

[shockley6668]

Thanks for reporting this. We've reproduced the issue and confirmed the broken link. The documentation team is already working on a fix and it will be updated soon.

In the meantime, you can access the 40-pin GPIO documentation directly here:

https://d-robotics.g...le/40pin_define

The only difference is that the URL should not include the .md suffix.

Thanks for your feedback!

Congratulations, you have unlocked your RDK Explorer title!

hi
thanks f0r feedback.
I'm trying to use a mono. but n0t stere0 (because 0f time c0nstraints) & als0 is midas_v2.1 supprted bu rdk x5 b0ard? (Ill f0ll0w quantise...)

[shockley6668]

Hi, vintage. We haven't tested MiDaS v2.1 on the RDK X5 yet, but you can certainly try converting and quantizing it. Please refer to our quantization guide.

Hi guys,
here is my Stage 2 submission:

Please have a look whenever you are free...
Thanks!!!
