Harmonic gear reducer
A compact gear, also called a strain wave gear, that uses a flexing toothed ring to slow a motor and multiply its force with almost no play.
A kind of part, not one product. Each of the 3 robots below has its own, and none of their companies say which model or whose it is. So there is no single price; the rough figure is what comparable products cost.

Why this price
The robot companies that use harmonic reducers buy them from suppliers such as Leaderdrive and do not sell them on, and their exact models are not public, so this is not their price; it is the price of comparable reducers a builder can buy. The range uses ready-to-buy strain wave reducers in the sizes and gear ratios used in robot arm and leg joints.
Our own figure, not a price from any company.
