Table Runner Car

Introduction

A table runner car is a type of robot that detects the surface when running on the table and never falls from the table. It’s a Kblox Neo-based robot that uses IR sensor to sense the surface of the table on which it is running and as soon as the IR sensor on the rover crosses the surface it stops detecting any object and the motors of the rover stop keeping it from falling through the surface.

Components required

• Kblox Neo
• IR Sensor [Qty-1]
• Chassis
• BO motor [Qty-2]
• Wheels 75mm [Qty-2]
• Castor wheel
• Screw-driver
• Rechargable Battery
• A to B USB cable
• Jumper wires

Code

#include"kblox.h"

kblox kit;
void setup() {

  Serial.begin(9600);                   //Intialize the serial monitor 
  kit.motor_begin(12, 11, 5, 3);        // define motors pins
  kit.ir_begin(9);                      // define ir sensor pin 

}

void loop() {
  int ir = kit.ir_read();              //Read ir sensor data and stored in variable ir 
  Serial.println(ir);                  //print stored data

  if (ir == HIGH) {                   // if ir sensor data is high move bot forward else turn bot left 
    kit.forward();
  }
  else {
    kit.left();
  }

}

Applications:

• In space rovers, to prevent the robot falling in craters
• Warehouse bots, which navigate the warehouse and are suspectable to stairs
• Follow me robots
