If you’re interested in robotics and looking to do something related to robots for your science project or exhibition, you are in the right place. You can make a robotic arm for your science project. It is an exciting and fun task to do. You also need not run here and there to collect the stuff required for a robotic arm. Just get cardboard and some thread, and that is enough.


Before making anything, it’s pretty much better to gather all the required stuff in one place to avoid any fuss.



  • Adhesive
  • Thread
  • Small thread holder
  • Cardboard
