Introduction
Technology is developing at a super-fast pace leaving us all mesmerized with the way it has made our lives easier and comfortable. 4-Wheeled drive system to talk about has become more and more advanced with time. This system helps make 4 wheel robotic cars more advanced than ever.
In this project, we are going to make a 4 wheel robotic car with a DIY kit. The assembly of this multi-utility vehicle is super easy and doesn’t require too many components. With this 4 Wheel Robotic Car, users can make car that can avoid obstacles, follow necessary lines to reach specified directions, and more.
What is a 4-Wheel Drive?
Four Wheel Drive (4WD) system is an essential part of the automobile industry. With the advancement in technology, we are seeing more and more changes in this sector. The vehicles now are more secure (on-road and off-road), there is improvement in traction of wheels and the power delivery of the engine too has improved tremendously.
What is BO Motor?
BO motor is a lightweight DC geared motor that gives good torque and RPM at low voltages. The BO motor has the ability to run at approximately 150 RPM when driven by a single Li-Ion cell. The BO motor is used for the lightweight applications and is available in different torque and RPM.
What is Motor Driver?
Motor Drivers are the current amplifiers that act as a bridge between the controller and the motor in a motor drive. These are made up of discrete components which are integrated inside an IC. There are two types of motor drivers viz. L293D and L298N. In this project, we will be using L298N motor driver.
- L293d Motor Driver is used to control the two motors at the same time. It is capable of controlling the speed by using the enable pin. This motor driver has a maximum continuous range of current close to 600mA but the maximum peak current range is 1.2A. It can be used to control the speed and direction of the stepper and DC motor.
- L298N is a high current dual full-bridge driver that is capable of accepting standard TTL logic levels. It can drive inductive loads like relays, solenoids, motors (DC and stepping motor), etc. Low saturation voltage, over-temperature protection, etc are some of its notable features.

Building Guide
Step 1: Assembling the 4 wheel robotic car
- Start by unwrapping the package
- Here you will find 4 wheels, 4 BO motors, 2 chassis (Top & Bottom), Battery Box, connectors, and nuts & bolts.
- Now connect the wires to the BO motors connecting heads.
- Repeat the same process for the rest of the motors.
- Now connect the BO motor to the base plate or the chassis with the help of connectors and tighten them using the screw and bolts.
- Now repeat the same steps for the other BO motors.
- Also, connect the red wire with the other red wire and black with the black as shown in the image.
- Now use the top plate of the chassis to create a sandwich-like structure.
- Use the connecting rod to connect the top and the bottom part of the chassis.
- Now connect the battery box to the top chassis.
- Now connect the wheels to the bot and we are done. Your 4 wheel robotic car is ready.
Furthermore with 4 wheel robotic car, you can make Line Follower Robot, Edge Detector/Obstacle Avoider Robot and more with the robotic car bot. Have you tried your hands on this project? If yes, do let us know what cool did you find about it.
