Stanford University researchers are working on an innovative robot called 'ReachBot', which looks like an insect with extendable legs. This robot is designed to overcome the difficult conditions of the surface and underground features of the Moon and Mars, including caves and lava tubes. The use of retractable leg technology allows the 'ReachBot' to adapt to uneven and potentially dangerous terrain that is difficult to explore with traditional methods.

A special feature of 'ReachBot' is its ability to significantly extend its legs, which allows it to move over rough terrain, cling to ledges and avoid obstacles. This makes it an indispensable tool for exploring planetary surfaces, where stability and maneuverability are critical for successful data collection and mission execution. In addition, the robot's modular design makes it possible to adapt it to various tasks and environmental conditions, which increases its functionality and versatility in research missions.

The study of subsurface structures, such as lava tubes, is an important element in studying the Moon and Mars, as these structures may serve as natural shields against radiation and extreme temperatures. Thus, the 'ReachBot' can not only collect scientific data, but also help in the search for potential locations for future bases or colonies. With its innovative capabilities and advanced technologies, 'ReachBot' has the potential to greatly expand the horizons of planetary exploration and facilitate future advances in space science and technology.
