Examples

This page provides complete, ready-to-use sketches for common Autobot configurations. Each example demonstrates a different drive type and feature set.

Installation

  1. Download AutOBot Library.
  2. Place the file in your Arduino project folder.
  3. Include it at the top of your sketch:
#include "AutOBot.h" // if you want to use the library without AI
#include "AutOBotAI.h" // if you want to use the library with AI

Differential Drive (2-Wheel)

Differential With Raspberry Pi

#include <AutOBot.h>
#include <AutOBotAI.h>

AutOBot myBot;
AutOBotAI myAI;

void setup() {
  Serial.begin(115200);
  Serial2.begin(115200, SERIAL_8N1, myAI.rx, myAI.tx); // RX, TX for AI comms
  
  myBot.begin(DRIVE_DIFFERENTIAL, 0);
  myAI.begin(Serial, myBot);

}

void loop() {
  myAI.handle();
}

Differential Without Raspberry Pi

A minimal sketch that drives the robot forward without any AI features.

#include <AutOBot.h>

AutOBot myBot;

void setup() {  
  myBot.begin(DRIVE_DIFFERENTIAL, 0);
}

void loop() {
  myBot.drive(0, 100, 0);
}

Mecanum Drive (4-Wheel)

Mecanum With Raspberry Pi

#include <AutOBot.h>
#include <AutOBotAI.h>

AutOBot myBot;
AutOBotAI myAI;

void setup() {
  Serial.begin(115200);
  Serial2.begin(115200, SERIAL_8N1, myAI.rx, myAI.tx); // RX, TX for AI comms
  
  myBot.begin(DRIVE_MECANUM, 0);
  myAI.begin(Serial, myBot);
  myAI.requestHuman(50, 0.5, 30000, 5000);

}

void loop() {
  myAI.handle();
}

Timed AI Sequence

This example demonstrates how to chain multiple AI modes using timers:

  1. Phase 1 — Follow a human for 10 seconds.
  2. Phase 2 — Follow a line for 15 seconds.
  3. Phase 3 — Stop.
#include <AutOBot.h>
#include <AutOBotAI.h>


AutOBot myBot;
AutOBotAI myAI;

unsigned long startTime;
bool phaseLineStarted = false;
bool phaseStopStarted = false;

void setup() {

  Serial.begin(115200);
  Serial.println("ESP32 Ready (AutOBot Mode)");

  Serial2.begin(115200, SERIAL_8N1, myAI.rx, myAI.tx);

  myBot.begin(DRIVE_MECANUM, 0);

  // Bind AI module with Serial2 and robot
  myAI.begin(Serial2, myBot);

  // ── Phase 1: Human Tracking (10s) ────────────
  Serial.println("PHASE 1: Human Tracking (10s)");
  myAI.requestHuman(30, 0.6, 30000, 5000);

  startTime = millis();
}

void loop() {

  // Always process incoming AI data
  myAI.handle();

  unsigned long elapsed = millis() - startTime;

  // ── After 10s → Line Tracking ───────────────
  if (!phaseLineStarted && elapsed > 10000) {
    Serial.println("PHASE 2: Line Tracking (15s)");

    myAI.requestLine(30, 0.8, 100, "black", 0, 0, 0);

    phaseLineStarted = true;
  }

  // ── After 25s → Stop ────────────────────────
  if (!phaseStopStarted && elapsed > 25000) {
    Serial.println("PHASE 3: Sequence complete. Stopping.");

    myAI.requestStop();

    phaseStopStarted = true;
  }
}

Mecanum Without Raspberry Pi

A minimal Mecanum sketch that drives the robot forward without AI.

#include <AutOBot.h>

AutOBot myBot;

void setup() {
  myBot.begin(DRIVE_MECANUM, 0);
}

void loop() {
  myBot.drive(0, 100, 0);
}

AI Mode Quick Reference

You can call these functions anywhere in your loop() — inside if, else, while, timers, or conditional blocks.

Line Tracking

myAI.requestLine(30, 0.8, 100, "black");

The robot will begin following a line. See the API Reference for full parameter details.

Human Tracking

myAI.requestHuman(30, 0.6, 30000, 5000);

The robot will begin following a detected human. See the API Reference for full parameter details.
