★ Power up the control board! ★
The design of the control board has been redesigned! Click here for specific changes ↓
(1) ESP32 is used for the communication module
We have adopted ESP32, which boasts high reliability, such as being widely used by IoT devices and makers!
It is also noteworthy that not only Bluetooth communication but also Wi-Fi communication is possible! * Separate development is required
② Strengthening of power supply circuit
Uses ROHM PMIC! By absorbing fluctuations in battery voltage, communication stability has improved!
③ Input / output terminals where ideas spread
We designed the board based on the ESP32 development board. Since it can be developed in the same way as Arduino, it is not a dream to install various sensors and run it automatically!
What is the difference between ESP racer and Mini 4WD?
The Mini 4WD released by Tamiya Co., Ltd. is a fun car model that runs along a fixed course.
But have you ever dreamed of running such a Mini 4WD freely outside the course?
We have developed a kit "ESP Racer" that makes Mini 4WD a radio-controlled model in order to make your dreams come true.
The conventional Mini 4WD is a toy that specializes in running forward, but by installing this radio control kit, the Mini 4WD can be made.
"Run!"
"Bend!"
"Stop!"
And with the programming features added to the app, autonomous driving is not a dream!
In addition, you can also develop an ESP racer for geeks from scratch!
It is a kit that realizes your dreams, far surpassing the common sense of Mini 4WD!
Features of ESP racer
1. Ideal for stay home!Everywhere on the course
From flat roads to bumpy roads, the course will be everywhere!
A speed race that won't catch your eye!
Overwhelming running performance!
Wild Mini 4WD has overwhelming running performance, and can run powerfully even on steps and slopes in the house. Large outdoor races are also affordable!
* Please do not play in dangerous places such as public roads.
* Please secure a social distance with others.
2. Easy control with the dedicated web application "bDriverMX WebApp"
The screen of your smartphone / PC can be used as a controller as it is!
We are developing and providing a dedicated web application "bDriverMX WebApp"! The differences from the conventional app are as follows!
(1) By making it a web application, you do not need to download the application and you can enjoy it more easily!
* You need to connect to the Internet to access the web application.
(2) The conventional app only adjusts the "steering sensitivity", but the web app can also adjust the "accelerator sensitivity"! You can also enjoy the fun of customizing it to your liking.
You can adjust the feeling to your liking with abundant setting items!
③ You can adjust the size and position of the lever so that you can use not only your smartphone but also your tablet or PC as a controller!
It is designed so that children and adults with small hands can play with peace of mind!
In addition, if you use the JavaScript programming function, you can automatically avoid obstacles just by pressing the start button.
3. Easy to assemble.Can be modified without specialized knowledge
* Modification to the ESP racer will be done during the assembly of the Mini 4WD.
How the ESP racer works
The ESP racer is a remodeling kit consisting of a small computer "ESP control board" for communicating with a smartphone and a part "steering parts" for turning the Mini 4WD left and right.
* Please purchase Wild Mini 4WD or MA chassis Mini 4WD separately.
* When modifying the MA chassis, it is necessary to process simple chassis parts.In addition, Wild Mini 4WD does not need to be processed
* Since the steering parts and control board are installed, some processing may be required depending on the shape of the exterior body.
1. What is a control board?
Explanation of each part of the control board
It is a computer for wirelessly controlling Mini 4WD from a smartphone / PC.
A small 3 cm x 5.5 cm board is packed with modules for Bluetooth and Wi-Fi communication, and electronic circuits for controlling motors and headlights.
2. What are steering parts?
A state where the steering part is removed
It is a completely original design part to make it possible to bend a commercially available Mini 4WD / Wild Mini 4WD that runs only straight.
By changing the steering angle of the tire with a small servo motor, it is possible to turn left and right.

Frequently Asked Questions about Rewards (FAQ)
Q: Is it easy to assemble? Can elementary school students make it?
A: Anyone can easily make it because we will prepare an assembly manual and a video. Even elementary school students are okay, but we recommend that parents and children who like Mini 4WD make and enjoy together.
Q: What do I need to program and run?
A: You need a computer that can communicate with the Internet environment via Bluetooth. In addition, you need to install Google Chrome on your computer.
Q: What language do you use for programming? What can you do by programming?
A: It's JavaScript. Functions for controlling DC motors and servo motors, turning on / off LED headlights, and basic loops, conditional branching, pauses, etc. can be described.
Q: What tools do you need to assemble?
A: In addition to the nippers required to assemble a normal Mini 4WD, you will need a Phillips screwdriver.
Q: Is it possible to convert the base Mini 4WD into an ESP racer without processing it?
A: Only the MA chassis requires simple processing (cutting parts). Wild Mini 4WD does not require processing. In addition, since the steering parts and board are mounted, some processing may be required depending on the shape of the exterior body.
