Read and know more about robots, then discuss together.
Robots are everywhere. They have been in space, under the ocean, and inside volcanoes. What do you suppose the future of robots be like?
In the future, robots may look, talk and walk just like people do. Some scientists say you may even have robotic friends in a few years, but for this to happen, robots must be able to feel and have emotions. Scientists have already made robots that can act like animals. “Robots will be much more like humans in the future,” a professor said.
Will robots take over the world? Most scientists don’t think this will happen. At least that is until robots can think. If a robot can’t think, it can only do what it’s told to do by people, so we don’t need to worry yet.。
