The results show that the camber deformation may play an important role in lift and drag coefficients. The positive camber deformation of the hindwing during the downstroke generates the vertical force, whereas negative camber deformation of the wing during upstroke generates thrust force. The freely flying dragonfly's hindwings play an important role in providing a stable lift force, and the forewings are very important for controlling flight behavior, such as turning, climbing and so on.

这些公式可用来计算机器人上各连杆的运动速度、加速度、惯性力，以及各关节上驱动器的功率和机器人的最大负荷能力。

Newton's second law of motion describes force. It says force equals the mass of an object, multiplied by the change in speed it produces in an object.

第二定律：F=ma，物体上的外力=物体质量*加速度，就是说物体的加速度，与施加在该物体上的外力成正比，定义了物体的质量就是物体惯性大小的量度。
