Line_Track_Arm_Bot

ESP32 Smart Car Robot 🤖

#Blockly_Programing

A smart robotic car using the ESP32 microcontroller. This robot combines line tracking, ultrasonic obstacle detection, and a robotic arm to detect, pick, and place objects along a defined path. Built using the ACB library suite.

🔧 Features

• Line tracking with adjustable thresholds
• Robotic arm to pick and drop blocks
• Ultrasonic sensing for obstacle detection
• Modular and extendable ACB library-based code

---

📦 Required Components

• ESP32 Development Board
• ACB Line Track Sensor Module
• ACB Robotic Arm (with servos)
• ACB Ultrasonic Sensor
• Motor Driver + Chassis + Wheels
• Power Supply (Battery/USB)

---

🧰 Library Dependencies

Install the following custom libraries:

• ACB_LineTrack
• ACB_CAR_ARM
• ACB_Ultrasonic
• ACB_ESP32Servo

⚠️ These libraries might be part of a vendor package. Add them manually to your Arduino libraries folder if needed.

🚀 Getting Started

🔌 Pin Configuration

Component	ESP32 Pin
Ultrasonic TRIG	13
Ultrasonic ECHO	14
Line Sensor L	39
Line Sensor M	36
Line Sensor R	35
Servo Arm Pins	25, 26, 27, 33, 4

🔍 How it works

1. Line Patrol: Follows a dark line on a bright surface using 3 infrared sensors.
2. Object Detection: Uses ultrasonic sensor to detect a block at 15 cm.
3. Pickup Sequence: Stops, positions the robotic arm, picks up the object, rotates, and places it in a target location.

🕹️ User Manual

1. Upload the code to your ESP32 via Arduino IDE.
2. Place the car on a track with a black line.
3. Place an object (like a cube) 15 cm in front of the ultrasonic sensor.
4. Power on the system. The robot will:
   • Follow the line.
   • Stop when it detects the object.
   • Grab the object and place it on the other side.
   • Continue patrolling.
