Overview

About DIY UNO Project Smart Robot Car Kit V3.0 (Line Tracking + Obstacle Avoidance + Bluetooth).

The DIY UNO Project Smart Robot Car Kit V3.0 is a complete 4-in-1 learning robot that teaches Arduino programming through four hands-on modes: IR line tracking, ultrasonic obstacle avoidance, infrared remote control and Bluetooth app control. It is modelled on the well-known Elegoo Smart Robot Car V3.0 design, one of the best-selling educational robot kits worldwide.

Everything is included and beginner-friendly. The kit is built around an UNO R3 board with an expansion shield, and every module connects with keyed XH2.54 plug-and-play cables, so there is no soldering and little chance of mis-wiring. That makes it a genuine plug-together learning experience rather than a bag of loose parts.

At around Rs 6039 it is a premium, all-in-one package aimed at students, hobbyists and educators who want a polished, tutorial-backed robot to learn coding, sensors and control. The bundled sample code and app let you get the car driving and reacting on day one, then dig into the code to understand how each behaviour works.

Buying guide

How to choose.

Choose this V3.0 kit if you want a complete, no-soldering, tutorial-backed robot to actually learn Arduino and robotics, not just a chassis. Unlike a bare chassis kit, this includes the controller, driver, all sensors, wireless modules, wheels, chassis and sample code, so a beginner can go from box to a working, reacting robot in one sitting.

It is the right pick for students, educators and self-learners who value a polished plug-and-play experience with documentation and app support. If you are on a tight budget or already own an Arduino and sensors, a cheaper generic chassis plus separate modules will cost less but requires more wiring and troubleshooting.

You will typically need to supply two 18650 Li-ion cells (and a charger) since cells are often not shipped in the box. After learning the four built-in modes, use the expansion shield and spare ports to add your own sensors and extend the sample code.

FAQ

Common questions.

Do I need to solder anything?

No. The kit is designed to be solder-free. Every module connects with keyed XH2.54 plug-and-play cables that only fit the correct port, so assembly is plug-together.

How is it programmed?

It is programmed with the free Arduino IDE in C/C++. The kit comes with sample code for each of the four modes, so you can upload working sketches first and then study and modify them.

What are the four control modes?

IR line tracking (follows a black line), ultrasonic obstacle avoidance (a servo sweeps the HC-SR04 to steer around objects), IR remote control, and Bluetooth control from a smartphone app.

Are batteries included?

The battery holder is included, but the two 18650 Li-ion cells are usually not shipped due to shipping rules. Buy protected 18650 cells and a charger separately.

Is it beginner-friendly and available in India?

Yes. It is one of the most beginner-friendly robot kits, with sample code and tutorials, and this Elegoo-style V3.0 kit is readily available from Indian robotics stores and marketplaces.

Can I add my own sensors later?

Yes. The UNO R3 with its expansion shield leaves free ports, so you can attach extra sensors and modules and extend the provided Arduino code for your own projects.
