Strengths and trade-offs
Our analysisStrengths
Not tied to one robot maker, so the same model can be taught on different robots.
A generous licence that allows commercial use.
Comes already trained on a wide range of tasks, so it needs less teaching to do a new one.
Trade-offs
It still has to be taught on the specific robot before it is useful.
Large, so it needs a strong computer to run fast enough.
It is built on a Google model, whose own terms may also apply.
Why robot makers choose it
Our readA robot maker that supports a well-known outside model lets its customers start from something that already works. For Unitree that is a selling point for the EDU version at no cost to itself.
This is our reasoning from the public facts. No maker has confirmed it.
