REX is an educational robot kit developed by the Robotistan R&D team. The 8in1 robot kit uses an ESP32-based mainboard that eliminates common setup challenges such as wiring complexity and connector confusion. In addition, it offers great flexibility by supporting Arduino IDE, Thonny IDE, MicroBlocks IDE, and REX Blocks IDE.
The REX board is a custom-designed controller board created to make the mechanical and electronic assembly of the robots in the 8-in-1 set easier. Built around the ESP32E processor, it includes connectors that allow you to connect all components used in the REX 8-in-1 set conveniently using simple cables.
To simplify assembly and circuit design for the 8-in-1 robots, the REX board includes connector ports for 4 DC motors and 4 servo motors, dedicated connectors for HC-SR04, IR, and MPU6050 sensors, a port for connecting an external 9V battery, and an integrated buzzer and switch.
You can check out the tutorial series we prepared for REX robots on the Robotistan YouTube channel.
Thanks to the REX robot competitions—first held in 2022—hundreds of students each year improve their robotics and coding skills with REX robots while enjoying friendly competition as a team.
ArmBot:
ArmBot is a REX robot that can pick up and move objects from one point to another using its robotic arm and a remote controller. The arm mechanism is driven by 4 servo motors. It can move across four axes (up, down, left, and right), allowing easy access to objects even in hard-to-reach areas. 
BalanceBot is a special robot that can stay balanced against external physical interference thanks to the accelerometer sensor on the REX board. You can use BalanceBot in scenarios where you need to keep objects balanced.
OmniBot provides easy access to any point without needing to rotate, thanks to its special omni wheels. With OmniBot, you can reach hard-to-access areas with ease. This robot is designed for convenient mobility in challenging spaces.
Omni wheels combine 360-degree freedom of movement with the stability of a fixed mount. This is achieved by an integrated roller design rather than a rotating mount. As a result, OmniBot offers 360° maneuverability, better directional control, and more precise positioning.
RoverBot is a REX robot designed with a tracked (crawler) structure that enables smooth movement on rough terrain. With RoverBot, you can easily perform tasks that require driving over uneven and challenging surfaces. Like other REX 8-in-1 robots, you can control RoverBot remotely or make it move autonomously with the code you write. 
SonicBot detects objects by emitting sound waves through its distance sensor and performs different actions based on measured values using its mechanical features. You can use SonicBot to avoid obstacles or for tasks that require detecting objects in the environment. 
SumoBot detects other objects on the track using the HC-SR04 distance sensor and line follower sensor. With the line follower sensor, it determines whether it is within the ring and pushes objects outside the track.
TrackerBot follows black lines by emitting infrared (IR) light using its line follower sensor. On a line-based track, you can create autonomous tasks by using TrackerBot’s mechanical capabilities. It is also possible to change the tracked color by modifying the code. To do this, you can analyze the sensor readings, determine suitable ranges for the desired color, and update the values in the code accordingly. 
WiBot is a REX 8-in-1 robot designed for remote control only, without additional sensors for autonomous driving. After completing the assembly, you won’t face any difficulty with wiring. By connecting the 4 motor connector cables to the REX board, you can easily perform remote-control tasks using the electronic features of the REX board and the mechanical design of WiBot—without needing extra sensors. 
Line follower sensors detect the presence of a black line by emitting infrared (IR) light and measuring the reflected light level. They typically do this using two key components:
Now that you understand how a line follower sensor works, you should learn how to use it. The line follower sensor also has a set of pins that you need to connect to your Raspberry Pi:
Warning! If you are using an 18650 battery on the board, please do not connect an external battery.
You can control REX robots via the PicoBricks Go mobile application. For detailed information about using the app, you can read the blog post below.
