THE COLOMBIAN
The rocky surface of the red planet led to the idea of a robot that would overcome the difficulties of the terrain and thus facilitate its exploration. It has a backbone and four legs.
A robot with mechanical characteristics similar to the movement of a lizard hopes to be the future Of Mars Exploration, the neighboring planet. The development of the biomimetic lizard robot was thought this way because the Martian terrain is full of rocks that sometimes prevent the movement of the rovers with their bearings. They know this because Mars has already had five of them: Sojourner, Spirit and Opportunity, Curiosity, and Perseverance.
This mechanism has been useful, however, in the face of difficulties due to terrain, scientists Guangming Chen, Long Qiao, Zhenwen Zhou, Lutz Richter and Aihong Ji of Nanjing Aeronautics and Astronautics University China, created a robot with a lizard appearance that is ready for exploration on Mars.

It was inspired by the structure and mechanism of this animal. That is, it imitates their movements. To make it work, the robot has a flexible spine that allows it to balance while walking on its four legs, made up of an active ankle, a round pad and four flexible fingers that will be used to grip soil and rocks.
“Mobility in granular soils and rocky surfaces is experimentally demonstrated, which may imply that this biomimetic robot is suitable for the surface terrains of Mars,” the researchers explained in a paper published in the MDPI journal Biomimetics.
The mechanism has been efficient, but before starting its exploration on Mars, some adjustments must be made, such as the construction of a protector that allows it to be in the Martian environment without being hindered by the amount of mud or dust that rises from the surface. .
