Introduction
Hygiene is the most
important factor for a clean and healthy lifestyle. A clean surrounding
contributes a greater aspect for a good health. So, it is necessary to keep the
surroundings neat and clean. If you see it on a practical level, it can be said
that cleanliness is related to hygiene and disease prevention. Household
cleaning is a repetitive task carried out by a few people day by day. Hence
there should be a bringing revolution in the field of science and technology which
could help easily in repetitive tasks which we perform daily. And considering
the intensity of labor that is required as well as improving the qualities to
its optimum level.
Figure 1: Isometric View of the Robot.
There are many types of
equipment which reduces the efforts of humans in cleaning. There are already
several big bulky floor cleaning machines that are widely available at the
market which is incapable of cleaning the remote areas which are out of reach
Figure 1.
There are machines that can clean and machines that can dry but a machine which
performs both functions is rare. Here comes the scope of the floor cleaning and
drying equipment for household purposes. This project is to design and
fabricate such a machine at an easy affordable price for usage in at every
house. The floor cleaning device which we have designed is more compact and
smaller in size than the usual model you see in the market. This floor cleaner
comes with a vacuum cleaner in the front and a hot air blower at the rear end.
The bottom part consists of a rotating mopping scrubber to clean detergent wet
floor. The objective of this project is to design and fabricate a robotic
vacuum cleaner with sweeper and blower unit which can save time in carrying out
the cleaning process that too with optimum cost as well as minimum power
consumption.
Aesthetics
The model developed by
us consisted of base stainless-steel plate and the above layer consisted of
transparent glass the nozzles were made of plastic. The size of this robot was
30x30x50cm (LxBxH). The future robot for the consumer purpose can be made using
a plastics or aluminum alloy
Figure 2: Detailed Parts.
A 3-D model of the
product with accurate dimensions and tolerances was drafted using solid works
software and the analysis was done for various stresses that could act on it
and calculations were made in order to select the desirable capacity of the
motor required for the smooth functioning of the device. Optimization of the
product focuses delivering of an ergonomic, comparatively cheap and efficient
cleaner and drier to the customer. The power drive for the scrubber is selected
to be electric and to be driven by a single dc motor. Considerations for the
storage and easy handlings are taken care. The cleaning brush is selected to be
of industrial grade. The blower unit is also selected in such a way that power
consumption was reduced as much as possible while keeping the machine in
efficient working condition Figure 2.
The main parts highlighted in Figure 2 are
1. Heating coil
2. Suction pump
3. Control board
4. Suction nozzle
5. Water container
6. Blower nozzle
7. 2/2 normally open Solenoidal valve
8. omni wheels
9. Scrubber
PCB Layer
The PCB Layer consist of
the ATMEGA 2560 Microprocessor which controls the robot, it consists of
Sharp-IR sensors and ultrasonic sensors placed at different angles so that the
robot can detect objects near it. The suction pump creates vacuum and sucks in
the dirt. The air is then cleaned using filter and then passed to the heater
coil where the air is heated up and then passed to the blower nozzle Figure 3.
The robot is powered by two powerful lithium-ion battery which can easily be
recharged. For the sprinkling of water, solenoid valve is used Figure 4.

Water Sprinkling System
The water sprinkling
system of this robot consist of a water tank placed at higher level and a 2/2
solenoidal valve. As the tank is placed at the higher level the water flows due
to gravity and potential energy. The valve is electrically actuated with the
help of a RELAY which is controlled by the ATMEGA 2560 microprocessor Figure 5.

Air Heating Process
Here the air sucked from
the suction nozzle by suction pump is passed to the heating coil where the air
is heated using a resistive coil and is then passed to the blower nozzle Figure

Advantages of the Robot
1. It is completely
autonomous
2. It has both vacuum cleaning and blower unit.
3. It has a water sprinkler to moisturize the floor for better cleaning
4. It requires less power as it uses single suction pump for both
5. Blower and vacuuming unit
6. It is light weight and flexible to use
