Why this price
Unitree makes this joint motor itself and does not sell it, so this is not its price. It is the price of comparable joint actuators a builder can buy that give roughly 70 to 120 Nm of peak torque from a motor with built-in planetary gearing, like the G1's hip and waist motors at about 88 Nm. In-house motors made in volume would likely cost Unitree much less.
Our own figure, not a price from any company.
