Intro: Arduino Agv With Infared Sensors Powered by Wind
This is a application of arduino.We make a line-following toy car,using the wind for thrusting.The car can turn and go straight along the line.Our motivation is eager to catch on the train trend that AGV is becoming more an more popular. It is a basic level of AGV,and is also a commencement of our future work.
Step 1: All Material Needed
Brushless motor ESC
Step 2: Setup
Connect a red wire from the 5V pin on the Arduino to the positive channel of the breadboard.
Connect a black wire from the GND pin on the arduino to the negative channel of the breadboard
IR sensor pin
dRR (最右側IR腳位) = pin 8
dR (右側IR腳位)=pin 6
dM (中間IR腳位 )=pin11
dL (左側IR腳位 )=pin1
dLL (最左側IR腳位)=pin 5
servo_pin = pin 10
ESC控制訊號 = pin 9
Step 3: Create the Chassis and the Steering Wheels
1. The servo motor ,Arduino,ESC,battery,,breadboard,attach to the chassis.
2.The servo motor attach to the linkage mechanism linking two front wheels for changing direction.
Step 4: About the ESC and the Dc Motor
The ESC is used to control the speed of the brushless DC motor,and is connected to brushless DC motor,11.1V -battery,and arduino with pin 9.However,there is no need to connect the 5v on the arduino,because it is powered by the more powerful battery.
Step 5: About the Fan
Using 3D printer to create a fan as the source of thrusting power is quite easy and efficient.Remember to create a hole of 3mm diameter on the axis.And then hook it up to the dc motor.
Step 6: Copy the Code and Install the Arduino Libraries
Open the new Arduino IDE page and Delete everything on the page
Get the code and Paste empty Arduino IDE page.
We set up a lot of cases in advance so that if the IR sensors meet the case,the car can do the accurate motion as we wish.
