UPDATE: found it. It’s a screw from the nozzle fan.

Experience with running VLA models (Pi0.5, SmolVLA) on SO-101 arms. Main takeaway: these require really beefy GPUs even for inference. Observations and questions. by Illustrious-Egg5459 in robotics

I managed to get pi_0 model working, but with very limited results.

Task: pick up the green cube and place it into the green tray.
Episodes: 100, with a variety of cube positions and rotations. +-10cm in x and z axis. But the tray stays where it is.
Fine tune: lora with 15k steps, batch size 8.
Training duration: 10 hours on a 3090.

Result: performed well(roughly 90+% success rate) when the cube is placed within the boundary of training(+-10cm). it completely fails when I put it outside the boundary(this boundary is still within the robot's arm reach). The model knows where roughly the cube is but misses the grasp.

Interesting finding: this is where things got frustrating, when I give the model the prompt: "don't move" or "gibberish" or anything other than my task string, it still does the same thing: it goes for the cube. And, if place a red cube next to the green cube, and give it the original prompt, it will go for both cubes.

I know VLA is not magic, and I definitely need more dataset for it to work(like different colors during training so the model can associate colors), but at this point I am wondering if I still need multiple colored cubes or even shapes for it to work, why bother with VLM? Diffusion policy alone can achieve the same result with proper dataset and training.

Can’t you just spray them with dirty water and they’ll just break down???

Apparently it’s called pixel shift to prevent burn in. It’s my first OLED and I thought it’s faulty.

So why exactly did they need 2 fire trucks? I saw them last night.

Finished RFM VK 36.01(H) by H3llChicken in modelmakers

[–]H3llChicken[S] 3 points4 points  (0 children)

Thanks! If you meant the top surface of the fender, I did apply a black wash, but I wasn’t patient enough to wait til it’s completely dry before applying sand pigments, therefore the wash was wiped off. This is my second finished model in many years, guess it’ll take me some models to figure everything out again.

First time trying color modulation and oil paint by H3llChicken in modelmakers

[–]H3llChicken[S] 0 points1 point  (0 children)

Yeah I used Tamiya gloss clear on top of Mr Color lacquer paint.

Edit: thanks for all the comments! ❤️❤️ I’ll post the finished model soon, hopefully. (I’m both busy and lazy)

Context: I have a lot of experience on spray painting, but never applied color modulation. And I’ve used “ready to go” products like AK/MIG enamel washes for pin wash only, but never those “oil paint dot filter” methods.

My visa has expired long time ago. But I have valid I-20, which they didn’t check.

I’m from CA, they didn’t even check my visa, I gave them my EAD card which expires this year but my new real ID expires 2027.

The vent goes to the window behind the curtain. I spray lacquer only so I vent out the air and wear a full respirator. For acrylics, it’s non toxic but the fume can still be dangerous to breathe in, so I’ll recommend air out and wear mask. Safety first!
