Wiring configuration Rombii has multiple wiring configurations for different modes of use. The following images shown a basic connection of the motors, the servomotor and the ultrasound sensor. Additionally, 3 configurations of the sensors and 1 of the speaker are shown, which can be alternated with the basic connection. Explore the different options and create new configurations. - Page 14 Connection of the servomotor: Connect the servomotor to the SD3 pins. Connect the orange wire to pin D, the black wire to pin G and the red wire to pin V. If it is necessary to change the position of the pins in the servomotor connector.
- Page 15 Connection avoids obstacles mode: Connect the left infrared sensor on D7 and the right infrared sensor on D0. The connector configuration must be Vcc (red), GND(black) and OUT (yellow). Left infrared Sensor Right infrared Sensor Infrared Sensor Connection line follower mode: Connect the left line sensor on D7 and the right line sensor on D0.

Connection position control mode: Connect the left encoder sensor on D7 and the right encoder sensor on D0. The connector configuration must be Vcc (red), GND (black) and OUT (yellow). Left encoder sensor Right encoder sensor Encoder sensor Connection speaker mode: Connect the speaker to D0. - Page 17 Wireless connection Rombii is based on IoT (Internet of Things) technology to communicate with you. You can control your robot remotely and without wires through a simple web page. You can communicate over Wi-Fi with two modes: a device-to-device direct access point or with a link router. With few simple steps you will use the technologies of the 21st century to be interconnected with your robot.
- Page 18 Once the web page is saved, the Snap4ESP 0.9.1.html file that will be stored on your local hard drive with a browser. Put the recommended batteries in the battery holder and turn on the Rombii robot with the switch placed in the expansion board.
- Page 19 AP. A new web page will appear and will determine the IP connection of the Rombii Click in the option robot ROBOT Copy the IP address in your clipboard. Rombii at this moment will have created a new network called WIFI XXXX, choose it and connect it.
- Page 20 Rombii shows the following screen:...
- Page 21 Now you are already connected though the Wi-Fi network with Rombii. Tell him what to do. Keep in mind that with this type of connection the Wi´Fi network is occupied and the device will not have access to Internet. LAN connection: This type of connection allows you to connect with your Rombii robot with a device with Wi-Fi technology (computers, tablets, smartphones) through a link router.
- Page 22 LAN. Then the software ask you to select the Wi-Fi network (router) that you want Click in the option connect it: Select the network and enter the password if is required:...
- Page 23 Click in "save" and automatically a new page be loaded into the browser, which reports the IP of the network. Snap4ESP 0.9.1.html Websocket Copy the IP address. Finally return to file and open tab, and click on the Connect WiFi (Enter your URL), where you must enter the IP address that block.
- Page 24 Block programming Rombii allows you to explore different programming languages with different difficulty levels. To begin programming, language block allows quickly develop basic programs for your robot to move and explore the world. Next, you learn how to upload examples, which will be automatically updated on the web. Subscribes to www.lab-robotics.com web, to keep you constantly informed of the news.
- Page 25 Once the example is open, you should follow the instructions detailed it. In the example keyboard_Remotecontrol, which is shown in the previous image, open the following programming blocks. As you can see, when you press the key indicated in the block (space, up arrow, left arrow, down arrow, right arrow) that block and the logic it contains will be executed.
- Page 26 www.lab-robotics.com For more detailed information visit the video tutorials at: Thanks to Internet and Wi-Fi communication, your robot always will be updated with new examples programs that you can find in the website, as well as its programming modes. Arduino programming If you want to program your Rombii robot with a more complex programming language , Lab-Robotics offers you the possibility to create your own programs with the Arduino language.
- Page 27 Click in OK and the software IDE includes third-party support. Now you just need to install the support for the Tools/Board/Card manager: ESP8266. Go to menu...
- Page 28 esp8266 by ESP8266 Community. Once the installation is completed, you choose the option Install the tool NodeMCU 1.0 (ESP-12E Module). Now the Arduino IDE programming environment is configured to use the ESP8266. take into account that once the ESP8266 is programmed with an Arduino IDE program, the previous pre- configuration for block programming will be eliminated and you will not be able to re-program in this mode.
