“…The significance of this rotational motion needs to be confirmed by reproducing it in a robot. Some studies have investigated the development of excavation robots that apply the burrowing mechanisms of animals (e.g., inchworms, shellfish, and earthworms) 15,[22][23][24] . The application of the burrowing mechanism of beetle larvae may also contribute to the development of new excavation technologies.…”

Many organisms live in the soil but only a little is known about their ecology especially movement style. Scarab beetle larvae do not have appendages to shovel soil and their trunk is thick compared to their body length. Hence, their movement through the soil is perplexing. Here, we established the observation and analysis system of larval movement and found that the last larval instars of Trypoxylus dichotomus burrow in two different ways, depending on the hardness of the soil. If the soil is soft, the larvae keep their body in a straight line and use longitudinal expansion and contraction; if the soil is hard, they flex and rotate their body. It is thought that the larvae adapt to diverse soil conditions using two different excavation methods. These results are important for understanding the soil ecology and pose a challenge to engineer of newer excavation technology.

A planetary penetrator is a kind of machine that can use its special structure to independently penetrate an exoplanet and sample it for storage. It is a hot research topic in the world and has important development potential in the field of deep space exploration. Based on the analysis of relevant literature, this paper classifies and compares various representative planetary penetrator projectiles around the current research status. The development progress and key technologies of the planetary penetrator are analyzed, the current technical challenges are summarized, and the development trend of the planetary penetrator has prospected. The planetary probe has a broad application prospect, and its development will provide technical support for humans to establish extraterrestrial habitat, and play an important role in the field of deep space exploration. Currently, planetary penetrator research is still in its infancy, and the field is full of possibilities that need to be explored and improved.
