The actuator at an angle can change greatly the primary jet direction and has a good effect on thrust vectoring without increasing input power.

在不增加激励器输入功率的情况下，带倾角激励器可以极大地增加主流偏转角度，推力向量控制效果很好。

Its second-generation Ankle Mimicking Prosthetic Foot (AMP-Foot 2.0) uses a pair of force sensors to determine the leg's relative position and let an actuator build energy when the foot bends, locking the power away to use only when the owner pushes off.
