Robots - for example "Curiosity" on Mars - can land on celestial objects, explore them and make an important contribution to the exploration of our solar system, just like an extended arm of humanity. And they are even part of our everyday lives: there are automatic vacuum cleaners and lawnmowers and the grip arm on the dustcart. The pupils examine a robot arm such as the one used on the International Space Station ISS, but of course the latter is much bigger. They can explore the practicality of robot arm models, steer them with a computer and, with a bit of experience, program simple moving processes that the system can perform automatically.
