REX8 8in1 Robot Kiti

REX is a maintenance educational robot kit by Robotistan R&D team. The 8-in-1 robot kit eliminates the following in circuit setups such as port, cable tangle with its outline using the ESP32 infrastructure. However, with the Arduino IDE, Thonny IDE and MicroBlocks IDE, taking action in the field of programming achieves great success.

The REX card is a special card designed to make the mechanical and electronic installation of the robots in the 8 in 1 set more convenient. This board, which uses the ESP32E processor, has connectors to easily connect all the components used in the REX 8 in 1 set to the circuit with a single cable.

4 pcs dc motor and 4 pcs servo motor connectors, 1 connection connector for HC-SR04, IR and MPU6050 sensors, to connect a 9V battery to the circuit externally port and 1 buzzer and switch integrated into the card.

ArmBot is a REX robot that enables the objects around it to be moved from one point to another by remote control, thanks to its robot arm. The robot arm on ArmBot consists of 3 servo motors. It can move in 4 different axes, up, down, right and left, and can easily reach objects in hard-to-reach areas with the movement of ArmBot.

Thanks to its special omni wheels, OmniBot provides easy access to every point without making any turning movements. You can reach hard-to-reach spots very easily using OmniBot. This robot is designed to reach hard-to-reach spots.

Omni wheels combine 360 ​​degrees of freedom of movement with the rigidity of a fixed mount. This is achieved with a design that uses integrated rollers instead of a rotary mount. In this way, OmniBot provides advantages such as 360° maneuverability, better directional control-tracking and precise positioning.

RoverBot is a REX robot that allows you to move comfortably in difficult terrain conditions thanks to its crawler structure. With RoverBot, you can perform missions that require rough, challenging terrain. Like other REX 8-in-1 robots, you can control the RoverBot remotely or move it autonomously with the code you write in it.

Thanks to its HC-SR04 distance sensor and line follower sensor, SumoBot detects other objects on the track it is on. Thanks to its line-follower sensor, SumoBot detects whether it is on the track and thus carries the objects off the track.

Thanks to the TrackerBot line tracking sensor, it emits infrared lights and follows the black lines in the environment. We can enable TrackerBot to perform the tasks we want autonomously by using the mechanical features of TrackerBot on the path we have created with lines. We can also change the color TrackerBot tracks by modifying the code. In order to make this change, we can examine the values ​​detected by the line following sensor, determine the required value range for the color we want, and change these values ​​in the code.

WiBot is a REX 8-in-1 robot for autonomous driving that does not contain any extra sensors and only allows remote control. After completing the WiBot installation, you will not have any difficulties with the circuit installation. After connecting the 4 connector cables required for the motor to the REX board, you can perform tasks that require remote control by using the electronic features of the REX board and the mechanical features of the WiBot without adding any extra sensors to the circuit.

Line Follower Sensor:

Line following sensors detect the presence of a black line by emitting infrared (IR) light and detecting light levels. They do this using two components:

  • an emitter
  • A light sensor (receiver)

How to Use Line Sensor?

You know a little more about how the line following sensor works, now you have to learn how to use it. The line follower sensor also has a set of pins that you need to connect to the Raspberry Pi you are using:

  • The VCC must be connected to a voltage between 3.3 and 5V to power the device.
  • GND is the ground pin required to complete the circuit.
  • AO is analog output (this pin does not work with Raspberry Pi.).
  • DO is digital output pin (this pin will work with Raspberry Pi.).
