We can make a vibrobot with a piece of name card.
Step 1: Preparing the Motor
First, u need to prepare the vibrating motor. I would use a flat one and solder the end with pins.
Step 2: Cut the Name Card and Making the Battery Holder
Step 3: Making the Body and Inserting the Motor
Step 4: Finished the Core and Fine Tuning
Step 5: Make Your Own Name Card Vibrobot
To make the vibrobot looking more like beetle, I add a pair of legs and 2 pairs of wings.
You can draw it, paint it and design your own.
I also use chocolate paper package to make a colorful one.
You can also add a pair of LED "eyes" too.
