I was looking at https://www.unitree.com/go2/ recently, which seems rather good value I thought. Some of the videos look really impressive, such as the back flips, climbing stairs and the lidar

Do they send it by pack mule or something?

Your parent should really check out the BOM on his iPhone or MacBook before complaining about $270 being "monstrously expensive" hardware. And all those gadgets benefit from high volume discounts on parts, decades of sunk R&D costs and the volume economies of scale, assembled by sweatshop workers, not niche low volume production runs for enthusiasts like this one. The price of Pizza at your local non-fast-food restau…

she doesn't have an iPhone or a MacBook because I do think they're expensive. I buy my phones used on eBay and cringe if they cost more than £50

I'm with you on this one, sister.

Don't even get me started on the kid down the street selling lemonade...

I still don't get it. Everyone here is male. Right?

Could be, but here I identify as strong independent Asian woman.

Cool. I identify as a giant robot super monster cat.

Is it just me, or is $269 monstrously expensive for some injection moulded plastic, plastic geared servo motors, an arduino compatible board, a battery and some connectivity modules?

Kind of, compared to high-volume products most consumers are used to see. R&D gets expensive fast.

Just try designing these up to first partial prototype and try calculating cumulative man-hour spent x local minimum wages x highly optimistic sales^-1 = pure R&D cost per unit before any manufacturing or even design reviews. It's not going to make a lot of commercial sense.

3D printing people sometimes says dollar stores makes them feel defeated. I'm not yet at that level but it's true, a 10-pack ball point pens at $1 makes very little sense if you knew.

I wouldn't say it is monstrously expensive, but it is kind of underwhelming at that price point. It doesn't even have three degrees of freedom on its legs, which is what I would expect on a basic quadruped.

It's a tradeoff with size. It's very hard to squeeze shoulder servos in and keep it that small.

I got one of these when I backed them on Kickstarter. It was a fun build and works well. I gave it to one of my neighbors' kids since I didn't really see myself using it all that much, and he enjoys it.

How old do you think kids have to be to engage with this? Considering buying one for my grandson who is pretty into legos/tech/etc. but is only 7

$1600 version is just a remote control toy. If you want the ROS programmable version it's around 10k.

They have a repository on GH with some of their projects code. The OpenCat page also contains information on how to calibrate the servos using a serial monitor, so that one isn't dependent on their phone app. Good! https://github.com/PetoiCamp Now, what about an updated meow/purr version for us cat lovers?:)

Looks like they also have a robot cat https://www.petoi.com/products/petoi-nybble-robot-cat

Yes, I already noticed, but it looks a lot less polished than the dog, and is also more expensive. Probably an older product with higher prices, that's why I would welcome an updated version.

There's also PuppyPi which looks quite a bit more solid (but is also more expensive) https://www.hiwonder.com/products/puppypi?variant=3977603314...

Unitree Go2 for $1600 is wildly capable. https://www.unitree.com/go2

Have you used it? What was the experience getting it into the US?
