Toys are fascinating. Who didn’t want that red flashy remote car in their childhood? Now, what if it’s not just a remote car but a car that’s actually smart. Let’s see what are the features of this car.

You power on this with remote control. The car can detect the kid’s presence. It also detects any other object/obstacle around it. After that, the car moves away from the kid, and also at the same time, it makes sure that it doesn’t collide with any other objects in its path.

Of course the kid is going to chase the car. Now when the kid is near, the car moves around them in different shapes to make it unpredictable and exciting. It also makes noise and uses flashy lights to lure the kid into chasing it.

Main features: 

  • Remote control for powering on or off
  • Detecting the Presence of kid nearby (360 Degrees)
  • Detecting any other Object/obstacle in its way and moving in a direction which is non obstructive
  • Making a sound or flashing lights when it is waiting for the kid
  • The car has random (circular i.e rotate around the kid) /triangle/rectangle etc) movements to make it unpredictable.

Now let’s see the technical aspects of this car,

Components required

So now that we understand the features we need, let’s see the components required to accomplish this.

Shakti processor based SoC

The main component driving all the sensors is the Processor. Shakti Processor used here is the India’s first indigenous microprocessor.

Ultrasonic sensors

An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. Here it is used for Object or obstacle detection in the Path of the Car.

Human detection sensor

Human detection sensor can detect the kid’s presence by sensing changes in human body temperature with respect to the surrounding temperature.

Remote control

It is used to switch on and off the car.

DF player mini module

This is a small, low price MP3 module with an simplified output directly to the speaker.

Servo Motor and Motor Driver

This is used to produce random patterns/movements of the car so as to make it unpredictable and exciting

Lights

LED lights are used to make it attractive.

Working of Smart car

  • Switch on the Car
  • Play Music & Blink Lights and wait for the kid to notice.
  • Scan 360 degrees to detect the kid (Can detect Human presence up to 1.5m) or the obstacle (Can detect obstacle till 5.5m)
  • Choose a path which is free and move in that direction.
