Scientists invented herbal robots to help people who are terminally ill but can't buy herbs.
The herb robot has four feet, and each foot has a sucker. If the sensor senses a steep slope, the sucker at the foot will spit out mucus and stick to the wall, and it will be sucked away when it leaves.
What should the robot do when it hits a wet wall? Don't worry! Every time before picking herbs, the robot will measure the temperature and humidity with sensors on the head. If the temperature is too low and the humidity is too high, it will shoot talons from its arms. When the "claws" retract, the robot will stretch out its claws from its fingers and grasp the rock wall tightly, and climb up step by step. I picked the herbs, and the machine automatically wrapped the uncle with a pull-back rope and landed.
If you think it takes a lot of electricity to use such a high-tech robot, then you are out. There is a "three-state converter" inside the herbal robot. Air can be converted into water, and the purified water can be sprayed out through a turbine to generate electricity.
The recognition function of herbal robots is also very strong. It can distinguish what is Ganoderma lucidum, what is ginseng, and the efficacy of these herbs.
Herbal robots may be developed in the near future, when terminally ill people will be well treated. As the master of the country tomorrow, I will study hard and make progress every day. When I grow up, more people will enjoy the dawn brought by the development of science and technology!
