Seems like a hallucination to me; note that the context contains “unmarkBlock” as the function name, which invites a connection to Minecraft. Still shouldn’t happen of course. The alternative explanation is that the inference engine, which

I agree with this. I recently went back to writing more code by hand again for this reason: the amount of effort / mental toll it takes me to steer the LLM is sometime just not worth it. I might be slower but I enjoy my work much more

There’s a lot of confusion here: - There is no double taxation if you just pay yourself a salary (since it’s a normal business expense). If you want to take money out of the company flexibly, a GmbH is the wrong structure. - I’ve never hear

Yeah I tried to use ROS / Gazebo about 10 years ago (it was still ROS 1) and getting it set up was an immense pain. I remember that creating new modules required writing CMake files. Maybe this is better now, but I decided to skip that

I’d recommend looking at the SO-101 then. Much much cheaper. And hardware is very fun! It’s also very frustrating. But to me worth it.

This all makes a lot sense, thanks for sharing! For depth I agree on the VLA route but for ACT / DP-style imitation learning from scratch it seems more feasible (since you’re not fighting a pretrained model that was not trained on this

Did you ever a late RGB vs RGB-D? I haven’t seen that much in the literature. Also any thoughts on action space representation? Seems to me people are settling on flow matching mostly, but pi still uses discrete tokens to supervise the upst

Yeah I can see that. Especially the rotation part is pretty awkward (hence why I currently do the axis parallel to table surface trick and only use the yaw angle to rotate the gripper). The space mouse was super easy to get started with tho

This seems indeed useful. I haven't seen this for robotics but I'm sure people need this for larger deployments (either for a distributed fleet or for an "arm farm"-like setup where there's many robots in one locati

Wow very cool project and thanks for the Ariel pointer! Added to my reading list. And yes, having a nice robot makes life so much easier. Very happy with my choice so far!

Oh very cool! Looks a bit like the TRLC-DK1 (I was looking at this one for a bit). I think pushing the sota is quite hard to do solo but we'll see. Mostly I want to get back up to speed after having not done much robotics during the la

I timestamp everything twice: once with the hardware clock (if available, like for the realsense camera) and once within my robot stack once it gets read from the device (using `time.monotonic_ns()`). Both are stored and alignment can happe

I'm only starting down this road but my sense is that ACT and Diffusion Policy both make it pretty feasible to start on real data only. LeRobot also makes it easier to train these. But that's the next step that I'm working on

Cool video! What made you stop if I can ask? And yeah I feel you re humanoid. I worked on the Rubik's cube project at OpenAI, which used a humanoid hand, and it was insanely painful and hard. Also fun anecdote: it was completely imposs

Great points and I very much appreciate the input! Right now the static camera is probably really bad: It's mounted on my desk, so its very easy to bump into it and move it. So yeah, it's position for sure will change over time. I

For understanding: I think the level is much deeper if I wrote the code vs reading someone else’s. Same applies to coding agents of course which is why I wrote most of it myself and only delegate some tasks (for example codex was great help

Glad you like it! Re your questions: - The driver situation turned out totally fine; I intentionally picked HW with good python sdk support so that was very painless. - The static camera (the C920) is not super great; it drops frames and so

It’s partially my fault I currently clip the max speed _and_ I only input soft control changes when teleoperating to avoid crashing into things. The robot itself could definitely move more quickly than what you see in the video. It would b

I think there‘s a serious issue with people using AI to do an immense amount of busywork and then never look at it again. Colossal waste.

I very much agree; I think laziness / friction is basically a critically important regularizer for what to build and for what to not build. LLMs remove that friction and it requires more discipline now. (Wrote some of this up a while a
