The Sony Aibo harkens back to the late 1990s. It was (roughly) the same, but cost >$2000 in 1990s dollars. TLDR: It's not expensive.

A luxury product for early adopters that looks great and works out of the box does not seem roughly the same to me than a device you still ultimately have to calibrate, expand (the default model of this doesn't even have a camera iirc) and program loads to do anything.

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

Just playing around with it with the remote they don’t have to be older than maybe in elementary school like my neighbors kid. If you mean assembly and doing some programming I would think middle school with an adults help for a few steps in assembly. Some of the toughest assembly is getting the wiring to go through to where everything can close properly, otherwise not too bad.

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.

We will roll out a newer version of robot cat around July. If you are interested in getting a notification, you can subscribe to our newsletter via our website.

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?

The bill of materials might not come close to that number, but materials are not the only cost when creating a hardware product. In your end price you need to factor in stuff like time spent on research, designing, testing, prototyping, writing & debugging software. Then there's manufacturing, packaging, storage, marketing and probably others. When you take all these into account plus the fact that this will not sell…

Our first robot Nybble cat was born as a maker project https://www.indiegogo.com/projects/nybble-world-s-cutest-ope... with crowdfunding in 2018.

Bittle was also born from our crowdfunding project on Kickstarter https://www.kickstarter.com/projects/petoi/bittle in 2020.

You can read about our history there.

In addition to the points you raised, one of the big challenges is to manage the supply chain and the bill of materials. For example, during covid, we faced the challenges of chip shortage.

For any hobbyist project, people don't really need to worry about things at scale.

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.

Bittle has a tiny body, but it has strong and fast servos for running and even backflipping(check this video https://www.youtube.com/watch?v=FRE-sp05ia8&list=TLGG0bKEfuY...). We custom-designed our own high-quality servos which are half of the prices of any comparable servos.

We already had a prototype with 3 degrees of freedom on the legs. But the structural complexity and price would have increased substantially. We are not releasing it at this moment.

Ok but it doesnt say anywhere on that page what you can do with the basic package?

It's a programmable robot dog that you can program in C++/Python/block-based coding. You can check the application links on the side bar menu at https://docs.petoi.com/

Ok thanks but what exactly can it do? Can it respond to commands and move accordingly? I am just a little confused how there isn't much immediate information about the capabilities of the robot, other than it's programmable. Programmable how? What's the trigger of the programming? What are some use cases?

> Shipping costs $399 per unit Do they send it by pack mule or something?

To be fair, I have seen with some of these robotics platforms they send them by air in a pelican case [1] with custom cut foam inserts. The price for shipping racks up quickly.

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

They do look impressive but the videos are all 3D graphics rather than real. The texture on the robot body and shadows are the giveaway.

I'm not sure why do you feel that's the case. It doesn't look like cgi at all and if it is shadows and reflections are flawless so the whole video including a person and lawns would need to be generated. I can't imagine how anyone could create it. Honestly building a robot seems easier than faking it to this level of accuracy.

Similar to how software engineers get paid $1000s just to keep hitting the keyboard.

Hey! Those keys are small! And there are so many!
