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 |
