Final year project : Floor Cleaning Robot

FLOOR CLEANING ROBOT

The Product developed is definitely a very important product in robotics and floor cleaning area . Also the algorithm implemented is not very effective. So there is definitely current scope for improvement and optimization till the most effective product is being developed. After optimizing the algorithm and taking it to the heuristic based search like bee algorithm it will be a great product and can revolutionize this industry. Definitely it has very huge potential. Also we can use 1 vacuum pump instead two so that it will be cost effective and very energy saving product with less vibration and much control over the robot. The robot having 33*30*8 cm in dimension is very compact in nature and can go beneath any furniture and bed. This is also very handy in portability. The scrubber of the robot now consists of small plastic fibers .But it can be further improved so that the surface area of the scrubber will come 90% in contact with the floor.

STEP FOR DESIGNING

STEP 1:- Required component list

1.   Arduino Uno R3

2.   L293D Motor driver IC

3.   Jumper wire

4.   Glue gun

5.   DC Motor 150 above rpm-3

6.   Water pump

7.   Scrubber

8.   Thin water pipe

9.   Chassis 

10. Dummy motor 

11. Bluetooth module HC05/HC06

Bluetooth app setup :- bluetooth-app-setting

STEP 2:- Circuit Layout

There are four motor, two motor for bot movement and two motor show as water pump and scrubber.

STEP 3:- PCB Layout and Breadboard Layout

STEP 4:- Coding part
