Introduction: Syringe Powered Hydraulic Arm
Can pick up and move soda cans, marshmallows, and play JENGA.
Step 1: The Idea
Come up with an idea of how you want to construct the arm and make a few preliminary sketches of what some of the parts may look like.
Step 2: Formal Design
Using CAD Software design a full model of what your final product will look like.
Step 3: Creation and Testing
Build the design you created using the tools you have available. I just used cardboard, hot glue, and some zip ties to make mine. Then test to see if it works.
