When people think of a robot, they generally envision a complex machine built out of wires that runs on batteries for electricity. However, I have created a simple robotic arm that is built from 100% recycled materials, commonly found in everyday households. Materials I used include cardboard, syringes, bamboo skewers, silicone tubes, wooden popsicle sticks, and an old clothes hanger. In addition to using recycled materials, my robot uses water as its motor rather than electricity, or in other words, it uses hydraulic power. How this works is that from one end, you can control the water by pushing and pulling the syringes, so that the water goes from one side of the tube to the other. When this happens, it results in the syringe on the other side to move, causing the robot to change positions. (Please refer to the video for better understanding). (Click entry image to view more.)
