Instruments like cameras are becoming smaller and more efficient, he points out, and Deep Flight II subs will have robotic arms.

相机这样的设备变得更小和更有效率，他指出，“深海飞行2”号潜艇将有机器手臂。

Deep Flight II will ideally replace the weights with a stronger lithium-polymer battery, so its thrusters can propel it down, making it more nimble in the water.

“深海飞行2”号将用一个更强悍的锂聚合物电池取代重量，所以推进器能促使其下降，从而在水中更灵活。
