How to build a robot car?

Building a robot car is an exciting and challenging project that can be fun for anyone with a bit of mechanical knowledge. In this blog, we’ll show you how to build your own robot car and explore some of the key components and technologies you’ll need. We’ll also provide tips on choosing the right parts and equipment, as well as explain the various steps involved in assembling your own robot car. So if you are looking to build your own robot car, this blog is the perfect guide for you!

Building a wireless RC robot car is far superior to building a wired robot, which you’ll have to follow while driving, whether you’re an engineering student building an off-road vehicle or an electronics enthusiast trying to impress people with your skills. . This is not really a robotics project. A robot is, by definition, something that decides based on some external parameters. Before you start telling people, “I build robots,” there’s a lot to do, but you have to start somewhere, right? This blog provides a simple step-by-step guide to building a Raspberry Pi robot car with only the most essential basic components and motors.

Building your chassis

If you are interested in building your own robot car, you will need to start by building its chassis. In this article, we’ll walk you through the steps required to build a chassis for your robot car. We’ll discuss the different materials you’ll need, as well as the steps required to build them. We will also give you tips on how to make your robot car easier to move and faster to accelerate. Read on to learn everything you need to know about building a robot car chassis!

Step 1: material preparation

You will need the following materials to assemble your EV car. If you’re not sure how to choose your component model number, read these instructions to learn how to assemble them into your vehicle.

You have the option of selecting one of the JGA-25 series engines. There are encoder versions of the JGA-25 series motors that can measure the speed of the car. In addition, you can select the TT engine. Despite underperforming the JGA-25 series engine, it is also more affordable.

We would have to select the wheel that corresponds to the motor that we select. You must select the TT DC MOTOR WHEEL if you want to use the TT motor. This product is not only of high quality, but it is also reasonably priced, making it a great choice. By replacing the coupling kit accessory, another wheel, the 6514A freewheel, can be combined with both the TT motor and the N20 motor. There are better products available in our store such as the 97mm Mecanum Wheel (4-packs) with four couplings that perfectly matches the JGA-25 and includes two nosepieces, two right hand wheels, and one hex tool. This would make your car more interesting and attractive.

We can choose the traditional microcontroller development board as the control core of the cars, such as Arduino, Seeeduino, etc.

You can also choose some of the most popular AI development boards such as the Raspberry Pi 4 and Nvidia Jetson Nano.

These motherboards would equip your car with artificial intelligence capabilities.

Grove sensor and motor control board

Depending on which MCU control panel you choose, select one of many different types of motherboards. We provide Seeeduino acrylic motherboards, Jetson nano acrylic motherboards and Raspberry Pi acrylic motherboards (coming soon).

The JGA25-371 Motor Bracket (https://www.seeedstudio.com/JGA25-371-Motor-Bracket-p-4118.html) can help you secure the motor during the mounting process.

In this guide, I’ve curated a custom acrylic motherboard, four matching jga-25 motors and jga25-371 motor mounts, a 97mm Mecanum wheel (4-pack), a Seeduino dev board, and two Grove motor driver boards. I2C as examples to show it. How to assemble a small car easily.

Step 2: Mount the wheel and engine to the body.

Bolt each wheel to the corresponding motor and secure the motor to the acrylic base plate like this:

Attach the motor to both sides of the plinths. It is necessary to pay attention to bilateral symmetry.
After fixing it on the motherboard, please try to rotate the wheels to make sure they can move normally.

Step 3: Secure the development board and motor control board

Secure the development board, motor control board, and battery box to the motherboards.
During the fixing process, it should be noted that the installation position cannot affect the movement of the carriages.

Step 1 Connect the battery box

The battery box has two connecting cables to the battery, one end is positive (red) and the other end is negative (black). The connection is as follows:

Connect the positive line to the Vin pin of the development boards.
Connect the negative wire to the Gnd pin of the development boards.

Step 2 – Connect the motor drive circuit:

Connect the positive pin of the motor to the Vin pin of the development boards.
Connect the negative cable of the motor to the Gnd pin of the development board.

If you are having difficulty identifying the pins, please refer to the online guide for the specific model.

Step 3 – Connect the motor to the motor control board:

Connect the positive and negative poles of the motor drive board to the two positive and negative poles of the two motors of the vehicles.

Programming the robot car

Are you interested in building your own robot car? If so, this guide is for you! We will teach you how to program the robot car using a programming language called Arduino. This language is easy to learn and can be used to control a wide range of devices, including robots. By the end of this guide, you will have learned how to program the robot car and will be able to use it to get around your home or office. So whether you’re a beginner looking to learn more about programming or an experienced hacker wanting to build your own robot car, this guide is for you!

Connect the computer and the program.

Connect the development board to the computer and open the corresponding Arduino IDE system. You can program the movement of the car through the Arduino IDE system. So, as shown below, I’ll just demonstrate the straight line and the rotation of the cars.
