Open-source and reproducible robotics platform
From 2 comments
Fantastic! Great to see a robotics framework that is no-frills (easily reproducible/DIY) and is immediately useful. Thank you for open-sourcing it.
sheepscreek on HNThis is brilliant. Are considering crowdsourcing the data from more people? It looks fun, and could save me time in the future, so I think this could be worth doing

Motion is jerky and slow

Great observation! Right now we rely on the out-of-the-box Hello Robots controller [0] implementing position control. Since our policy only predicts a single position into the…
MahiShafiullah on HNIt’s so hilariously slow and jumpy, it moves like a cautious chipmunk! I’m sure it’s gonna be awesome but it is so MVP right now. Also those “houses” in the demo videos are like…

Hardware prototype is too expensive for home buyers
From 3 comments
Looks awesome. The Hello Robot shown is fairly pricy. (From the site: "A Fully Integrated Mobile Manipulator for $19,950"). What are the options to do similar manipulations for…
rexreed on HNI'm no marketing expert. But I'd think the majority of those who have an extra $20k to splash on a home robot are not the type of people who want to buy a prototype for hacking.
ranting-moth on HNSame thought. For 20k$ you can get a car. What you get here, at least looks like, a roomba with an arm gripper. I understand why it is so expensive, since it is not a mass…

Privacy risk from home video data collection
From 1 comment
Privacy would be a big part of it. Video of my home could potentially contain lots of private information. How is that risk minimized?

Support for multiple manipulators
From 1 comment
I was thinking on buying/building one robot like this to experiment. Can one fit more than one manipulator on it (so it could more easily do things like hang out clothes, or hold…

Pick-and-place and carrying heavier weights
From 1 comment
Can it handle any weights on its own? Carrying stuff is definitely one important task that could be useful for lot of people.

How to crowdsource data with incentives and privacy
From 1 comment
Thank you! Yes, we have considered launching an open source effort to scale up the data, perhaps to be comparable to what Google has collected through paid tele-operators [0].…

Unitree Go2

Yeah that price is ridiculous considering the price of the go2 https://shop.unitree.com/en-gb/products/unitree-go2 the go1 can be had incredibly cheaply via aliexpress as well.

Comma Body
From 1 comment
I don't think I've seen anyone else suggest it- the Comma Body might be an interesting platform for this. No manipulator unfortunately but a decent place to start.…
