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.

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