Autonomous weeding robot

this robot is using in farmer to Watering plants and cut harmful plants

The robot works without being controlled by a human operator. It covers the ground just by getting its bearings and positioning itself with the help of its camera, GPS RTK and sensors. Its system of vision enables it to follow crop rows, and to detect the presence and position of weeds in and between the rows. Two robotic arms then apply a microdose of herbicide, systematically targeting the weeds that have been detected.

Autonomous weeding robot

this idea is more perfect but need more effort to complete all feature to cut plants and drinking planets

this scale in this project will help you to add all feature for example camera and solar panels

Project Construction

2. Explain the CAD process of your project. How did you use the software to design your project? (List the softwares/tools/materials...etc that you used)

i used fusion 360 to design cars which do the function

first i searched in google about idea of cars modules

design first part it's the bottom of the car that to fixed wheels in it

the most challenge in this project was dimension because it should be not small and large the perfect size was 20*30cm

and second challenge was how to fixed motor in body of car

and how to distribute the component because should be stable

design second part which fixed to plate with other by using T-slots

design hole on the plate to fixed container between to plate up and dawn

using laser software to edit in the file speed of cutting and scan and edit sketch in the sheet

fabricate using laser cutter

3. Explain the fabrication process of your project. How did you use the machine to fabricate your project? (List the softwares/tools/materials...etc that you used)

I took a sheet of wood from the cupboard

To notice is it flat or not

second , transfer file to the pc specialize laser cutter

2- choose file and press

3- select original point

4- show the frame before running to cutting

5- start to cutting and close the door of the machine

design container by using fusion 360

to get the idea was very complex because the weight will effect about the care

using 3d printing to fabricate modules

first open file in prusa to edit in it

type of filament and type of machine mk2s

and setting infill to 50%

first, we transfer file design from my memory to the memory card

-select file from 3d-printing

- change filament with heat and change the filament roll

- clean the bed before running

Project Electronics & Power Management

4. Describe your electronic circuit. What are the input and action components? What is the function of each? How do the components integrate together to form your smart system? (List the softwares/tools/components...etc that you used)

component list

action component

4 DC motor : DC motors are the most simple motors to use. They can reach a high rotational speed that is dependent on the input voltage. However, it can not handle the position as one would with a servomotor or a stepper motor

pump : to left the water to watering the planets

Arduino Uno ; to control the input and output component

motor drive ;to control the speed of the motor

using tinker cad to simulate the component

first ; search about data sheet of motor drive

to know the input and output

5. What is your power source? How did you select the suitable power source for your project? (List the softwares/tools/components...etc that you used)

the power source was battery 1000mAh and 7 V

after search in data sheet volt and current

from data sheet;

DC Voltage: 2.5-6V
Flow rate: 80-120L/H
Power: 0.4-1.5W

from data sheet;

4x Robot Wheel 65x26mm + 2 x TT Motor (3~4.5 Vdc)
70 mA

calculate manually suitable battery

power require

Project Programming

After simulate the component in tinker cad

start to fixed component in the car

bread board

Arduino Uno

battery

the most challenge to part the area to include all component after that start to write code

6. Describe the code of your project. How did you program each function of the project?

after finishing wiring component i used Arduino 1.8.13 software to programming project and control it

first steps was write code about dc motor (A )

the int enable was in pen 1

and motor B was in pin 6

write all pen input in which in Arduino

after that setup ultrasonic sensor which define trig pin & echo pin connected in pen 8&9

after that knows the input and output

use loop order to complete the function in the loop and return it again

after that create a motor function

to digital write and analog write

pin A1 to high

pin A2 to low

repute that but replace the number of motor B ,C,D

finally know the ultra sonic and the space that is detected and using while order

Project Integration & Testing

7. Demonstrate with text and visuals how did you integrate the project’s modules together? What are the testing results? (Include a Demo video separately, showing a proof of functionality)

first step

design project by using fusion 360

install all part with other

install all component and fixed it

wiring system after using tinker cad

finish project and start to write code

programing component by using Arduino software

test project

Sharing & Collaboration

8. Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

I asked sheriff and Ahmed Saied about a feed back after fabricate the project

the idea sherif suggested that was how to fixed pump in a container because if it not fixed will be vibration

some friend help me in code to using motor drive and Bluetooth module

the point i have research to push up it how to fixed the motor in the part of the car and search about a lot of design to know how but Ahmed Saied help me in lap it show me the same project in the lap and I know how to fix the motor

and i design small part in lap and fabricate it

Overcoming Challenges

9. When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?

the most problem was in final project was the time

because the final exam and final project in the same time but i handle it

the point i have research to push up it how to fixed the motor in the part of the car and search about a lot of design to know how but Ahmed saied help me in lap it show me the same project in the lap and i know how to fix the motor

next problem was happen small shift in par around the wheel the wheel was Friction with car body and i used tools in lap to friction the body conflict with it

next problem was pump

the are some problem in the pump and i till Ahmed saied about it not running

Future Work

10. If you had more time, what is one thing you would change/ Do next in your project?

if I have a lot of time I will using Bluetooth module

and power from solar panel

I think if I have time I don't need to change any component but I will add some component
