Step 1: Idea

This project works on an excellent deal of reflex mechanism.It involves a basic idea of developing an “AUTONOMOUS HOOVER”,that helps to reduce the daily work chores at houses,offices etc..The work of this device is to suck dust and stack those in the storage section provided along with.

To facilitate targeted functions, interactivity with high quality infrared and dirt sensors play an essential role.

Additionally, a navigator is suited to accomplish the task by the device itself so that, it could detect any obstacle on its path and move accordingly without the user’s intervention, by fixing rotator at the base of the device. Moreover, it could sense steep drops and retrace a portion of the path taken in order to avoid falling.

This versatile device could carry metal detectors that can be incorporated within the device in order to filter out valuables along the cleaning area.

According to a particular sequence of interacting with the hoover and the user,this machine can be operated anywhere by using Intel Edison Hence the data can be updated in cloud database for monitoring purpose.

Besides the involuntary sucking function,a wireless voice command is used remotely and also the path can be recorded.

To achieve this, an Intel Edison board would suffice.

The benefits of this device are many besides keeping the surface cleaner, can operate remotely saving time for people and lower maintenance cost as well.

Step 2: Hardware Required

Intel Edison

servo motor

proximity sensor

Infrared sensor

Dust sensor

Brushless motor

Small propeller

LCD display

Batteries

2-channel relay board

Temperature sensor

Step 3: Procedure

Ø

Design a 4 wheeled bot for the hoover to run.

Ø Back wheeled motors are each connected to 12V DC supply.

Ø Inorder to interface the intel board with the bot,a 2- channel relay board is connected which helps in stepping down the voltage as well.

Ø The system with arduino software connected with the intel Edison board, is programmed and dumped into the same for the following result:

The dust sensor is used for sensing the dust and displaying the dust value in the LCD display. The proximity sensor is programmed so as to avoid any obstacle.

Ø The machine would stop automatically when it detects an obstacle and proceeds by sucking the dust.

Ø For sucking the dust,the machine uses the air blower that’s set in front of the bot.

Ø The air blower runs on 12 V DC supply.

Ø To store the dust,a stack session is provided along the sucking out section of the air blower.

Ø A scrubber is placed at the back of the bot to clean the area soon after it sucks dust.

Excellent!

And if you do(n't) like it, you can register the domain "hooversucks.com" which would actually mean that Hoover has good suction,

which would actually mean that Hoover works great.

Cool..

thank you for your comments,means a lot to me! would be updating you by detailing it..
