Introduction: BugBot

About: I am IT professional, living in Bangalore, India. As new gadgets come out everyday, we indulge in spending significant time and money on these gadgets. And our kids are learning from us, they know how to use...

My son wanted to make a something for his school's science exibition. Since he is just 8, I wanted to a project that is age appropriate and where he could follow my instructions to assemble one

Out of many ideas, we decided to make a bugbot. Basic idea was it has a motor with unbalanced load, causing it to vibrate, The motor is resting on a wooden piece with 6 legs, giving it a bug / insect look

This is project can be assembled my kids under adult supervision
