Description

Technical Field

[0001] The utility model relates to the field of teaching aids and demonstration supplies, in particular to a Martian robot used for demonstration. Background Art

[0002] The Mars rover, also known as the Mars rover or Mars rover, refers to a mobile probe that lands on Mars for Mars exploration. It is a vehicle launched by humans to travel and conduct surveys on the surface of Mars. There are some expansions of celestial knowledge in modern textbooks. Usually, in order to satisfy children's curiosity, they will organize visits to science and technology museums on weekends to learn about the Mars rover. Some of them are demonstrated through robot models. The existing Mars rover robot model focuses on imitating the appearance of the Mars rover and achieving the ability to walk in a similar Martian surface environment. It mainly uses common parts such as Lego blocks to build the appearance, and assembles off-road tires and motors to achieve the ability to walk in the wild. However, the above method has a single structure and poor functional demonstration. Due to insufficient scalability, it cannot be effectively demonstrated to students in the classroom or amateur environment, so it cannot arouse students' good interest and provide a favorable learning environment for students' independent development.
