Joint actuators, model not named
The motor units that move each joint; the maker does not give them a model name.
A kind of part, not one product. The robot company does not say which model or whose it is. So there is no single price; the rough figure is what comparable products cost.

Why this price
Booster does not name or sell the T2's joint actuators, so this is not their price. It is the price of comparable joint actuators a builder can buy, from about US$300 to US$400 for wrist and head size units around 22 to 25 Nm, up to about US$900 for leg size units with about 120 Nm of peak torque. None of them quite reach the T2's 135 to 144 Nm hip and knee figures, so a T2-class leg joint could cost more.
Our own figure, not a price from any company.
