Test your knowledge about robotic arms based on the text below

Good morning, my friends. I’m going to show you what I have created from used materials. I call it “The Robotic Arm”. This arm is made of cardboard, straws, elastic, and strings. With this arm, you can take things without really touching them. The arm is just like our hand. I can say that it is the extension of our lower arm. We put it on our wrist. There is a piece of elastic to hold the robotic arm. It is designed to follow our hand’s movement. The strings are attached to our fingers so we can move the robotic arm easily. We move the fingers by pulling the strings
