B.Happy but tiring.
C.Long and colorful.
D.Short but enjoyable.
D
Scientists from China have created a truly remarkable robot hand! Named the “F-TAC Hand”, it was developed by researchers from Peking University and the Beijing Institute for General Artificial Intelligence, and their exciting work was just published in the famous science journal Nature Machine Intelligence on June 9th, 2025.
What makes this robotic hand so special It can feel and adjust its grip just like a human hand can. Imagine trying to pick up a ping-pong ball with just your little finger, or holding both a baseball and a golf ball in one hand without dropping them. The F-TAC Hand can do these things! If it picks up a cup full of water, it automatically adjusts its hold to keep the cup steady and prevent spills — reacting faster than you can blink.
The secret lies in its amazing touch sensors. Covering 70% of the hand’s surface, these tiny sensors — packed as densely (密集地) as 10,000 per square centimeter — let the hand feel textures, pressure, and any tiny movement of the object it’s holding. Crucially, these sensors are built right into the hand’s structure, so they don’t make the hand stiff or clumsy. A smart computer program uses this constant touch feedback to instantly decide the best way to grip different objects, just like our brains tell our hands what to do.

9． A．因为杯子的质量不变，杯子受到的重力不变，故A错误；
B．因为杯子始终处于静止状态，杯子受到的合外力始终为零，故B错误；
C．由于杯子受到的合外力始终为零，杯子受到的摩擦力始终与重力二力平衡，杯子受到的摩擦力不变，故C错误；
D．若手握杯子的力增大，手与杯子间的正压力增大，最大静摩擦力增大，故D正确。
故选D。
BQ段的细线竖直，所以AQ段绳子没有拉力，即BQ段的细线的拉力等于mg，根据平衡条件，物块P受到平板的摩擦力等于mg.故选B.
当木块受F1、F2及摩擦力的作用而处于平衡状态时，由平衡条件可知木块所受的摩擦力的大小为8 N，可知最大静摩擦力Ffmax≥8 N．当撤去力F1后，F2＝2 N
