If you want to understand the soil conditions of a place, it’s OK to observe earthworms in an ideal state. However, in the actual operation process, it is often impossible. Therefore, inspired by earthworms, scientists have developed an agricultural robot for soil analysis. The robot, developed by Cornell University in New York, is between 1-2 feet (30.5-60 cm) long. < / P > < p > the front of the robot is similar to a auger and can drill into the soil, and the rear will slide forward repeatedly, accumulating the discharged dirt in the wall of the final passage. This movement characteristic is inspired by simulating the movement of earthworm through soil. The robot can be used to confirm the density of the soil after it has been drilled into the soil. At the same time, the integrated sensor will measure its temperature and humidity. In addition, fiber optic cables can be used to image plant roots in soil and measure microbial activity and the level of carbon compounds released from the roots. < / P > < p > since radio waves cannot travel well through the dust, all data will be recorded on the robot for subsequent retrieval. But in the future, it is possible to transmit data to the ground by acoustic means. Once all the data are collected and analyzed, they can be used to predict yield, evaluate stress tolerance of crops and even assess their response to climate change.
