Self-building robot - level 2
American scientists created a new robot. When they apply heat to it, the robot builds itself in under five minutes and walks at 5 centimetres per second. It does not need human help.
People can use this technology to build machines and to help in harsh environments like space.
The “origami robot” is pretty cheap to make, too. You can make the robots from easy-to-find materials which cost less than $100.
Difficult words: apply (use), harsh (difficult to live in), environment (place).
You can read the original story and watch the video in the Level 3 section.
