Mr.robot vr-1.0 (2013)

Sunday, August 23, 2015



This is my robot for many purposes ,made using arduino and some other sensors. This robot can function as obstacle avoider, bluetooth controlled robot etc. it sense fire ,smoke,gas and any of them detected it make alarm sound. We can use this robot in home for security and use as pet.



Let's start making





Parts you need -


Arduino
Circuits like fire alarm etc





Arduino

l293d motor controller


Hc-sr06 
Motor

Some plastic tins







Some pics on making this












Adding ldr alarm system alarm



Adding smoke alarm










Adding fire alarm










Adding fm transmitter








Adding main parts like arduino board












Adding ultra sonic sensor




before spray painting
