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.
Connection of the battery and motors:
Connect the red wire of
the battery holder to the
VIN connector and the
black wire to the GND
connector of the
expansion board.
Connect the red wire of the
left motor on the connector
A- and the black wire of the
left motor on the connector
A+ of the expansion board.
Connect the red wire of the
right motor on the B+
connector and the black
wire of the right motor on
the B- connector of the
expansion board.

Connection of the servomotor:
Connection of the ultrasound sensor:
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.

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.
Access Point connection:
This type of connection allows you to connect with your Rombii robot through any device with Wi-Fi
technology (computers, tablets, smartphones). You will not need to have access to the internet, the access
will be directly between devices. The connection configuration is detailed below.
First you should to access the website of www.lab-robotics.com/Software and a new browser tab will be
opened with the Snap4ESP 0.9.1 software. Then download or save the web page with the option provided by
the browser that is being used. You can also pre-load the example page that you want to use, by accessing
to blank page menu/Open.../Examples.
16

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. The Wi-Fi networks will be checked with your device (computer, tablet or smartphone),
and select the WIFI SELECT MODE XXXX, that is your Rombii robot. Connect to the network and then the
following screen will appear:
17

Click in the option Use AP. A new web page will appear and will determine the IP connection of the Rombii
robot
Copy the IP address in your clipboard. Rombii at this moment will have created a new network called ROBOT
WIFI XXXX, choose it and connect it. Finally return to Snap4ESP 0.9.1.html file and open Websocket tab, and
click on the Connect WiFi block. The following screen will open (Enter your URL), where you must enter the IP
address that you previously saved.
