Making an Impressive Working Robotic Arm from Cardboard

Source: makezine.com

This project demonstrates how to build a fully functional robotic arm using hydraulics powered by water-filled syringes. The structure is crafted primarily from recycled materials like cardboard, popsicle sticks, and household items, utilizing syringes to translate fluid pressure into mechanical motion.
