The OSOYOO FlexiRover Robot Building Kit for Arduino is a customizable and versatile robot chassis designed for those aged 15 and up, particularly users with experience in Arduino robotics. While the kit does not include a board for Arduino, it is compatible with a variety of Arduino models, allowing users to select the controller that best suits their needs.
Included in the kit are four TT motors with pre-attached wires for easy setup, alongside four durable wheels that ensure smooth, reliable movement on different surfaces. The motors connect to a convenient plug-and-play motor driver board, simplifying the setup process and allowing users to focus on their programming and development work instead of spending time on complex wiring.
The kit also includes a battery holder with an integrated on/off switch, designed for use with 18650 batteries (not included), ensuring that power management is efficient and reliable during extended periods of operation.
What makes the FlexiRover stand out is its customizable chassis. Featuring multiple pre-drilled holes, the chassis allows users to easily attach various sensors, cameras, mechanical arms, and other add-ons, offering flexibility for a wide range of robotics applications. This makes the kit ideal for experimentation, educational projects, or building more advanced robotic systems.
With this kit, users can explore and expand their skills in robotics by creating unique, customizable robots tailored to specific needs and projects.

Package List
Hardware Installation
Install devices
1) Preinstall 4 TT motors with Metal Motor Holders as follows
2) Install 4 motors on 1st layer car chassis(metal) with M3*10 hex screw (screws in metal motor holder package)
3) Install 4 wheels on motor and fix these with screws for wheels
4) Flip the car chassis from the last step and install OSOYOO MODEL X motor driver module on the other side of 1st layer car chassis(metal) with 4pcs M2.5 plastic screws, plastic pillars and plastic nuts.
4) In this sample project, we take UNO board as an example. Install OSOYOO basic board for UNO on upper car chassis with 4pcs M2.5 plastic screws, plastic pillars and plastic nuts. (Please make sure you install the board at the correct side)
5) Install battery box with DC connector for 18650 batteries. Install this Battery Box on upper chassis with 4pcs M3 x 10 screws and M3 nuts.
Connection
1) Connect 4 motors to OSOYOO MODEL X motor driver module K1 to K4 sockets as per following graph:
3) Connect OSOYOO MODEL X motor driver module 6 control pins to OSOYOO basic board: ENA-D9, IN1-D12, IN2-D11, IN3-D7, IN4-D8, ENB-D6 with 6pin female to 6pin male jumper wires as per following graph
Caution:
When insert/remove this 6-pin plug into Model X 6-pin male socket, please hold the black plastic pin-holder to do operation. Never drag the wires to pull the plug out of the socket, otherwise it will damage the wires.
4） Connect the board, battery box, and OSOYOO MODEL X motor driver module according to connection diagram
5)Connect upper chassis to lower chassis with five copper pillars and fix copper pillars with 10pcs M3*10 screws and 10pcs M3 rubber rings, then install 4 wheels onto the motors.
Now hardware installation is almost down. Before we install 18650 batteries into the box, we need burn the sample code into board First.
Step 3: Connect OSOYOO basic board to PC with USB cable, Open Arduin IDE -> click file -> click Open -> choose code “v2smartcar-lesson1.ino” in smartcar-lesson1 folder, load the code into the board. (Notice: Shut off your battery or Unplug your power adapter when upload sketch code to the board.)
Step 4: Choose corresponding board/port for your project, upload the sketch to the board.
Step 5: Disconnect the car from PC, install 18650 batteries into battery box （Note: Check the box instruction and make sure polar direction is correct, otherwise it can destroy your device and cause fire hazard.)
Step 6: Put the car on the ground and turn on the switch on battery box. The car should go forward 2 seconds, then go backward 2 seconds, then left turn for 2 seconds, then right turn for 2 seconds, then stop. (If the car does not move as per above-mentioned result, you should check your wire connection and change the batteries）
