Thank You & Congratulations!
What is rero?
Areconfigurable robotics Construction kit with flexible slide lock assembly mechanism. rero does not use screw,
bolt or nuts for assembly instead it use novel slide lock mechanism which make it so simple and time saving to
complete a robot.
rero come with loose parts which empower user’s robot building creativity and imagination. rero parts can be
combined to build up robots, redesigned, taken apart and put back together in multiple ways. There are no specific
assembly rule that limits the user to build up new robots.
rero has several programming methods. The most basic way to program a complete rero robot is Teach Mode. User
teach rero and rero replay back what it remember from the teaching. With rero animator, user can create time-lined
motion sequences similar to making an action movie for rero.
Boost Your Creativity and Imagination with rero !

3.1.2 rero Cube Servo (G15)
Cube Servo
Cube Servo is a Servo motor that user can set it to rotate and position it to certain angle position. It can also operate
in wheel mode for continuous rotation.

To test Cube Servo using rero controller, connect the Cube Servo to rero controller. Go to ‘Servo’ Menu. In the Servo
menu, select the servo you want to test from the list of connected servo. LED on Cube Servo will light on when
selected. Drag on the round meter to change the position angle of the servo.

3.1.3 rero Head Module (RR-SH-01)
rero Head Module has build in sensor of IR sensor and Sound sensor. It has 2 RGB LEDs as the eyes. rero Head
module can be attached to Cube Servo give Head Module the flexibility to move or rotate.

User can test rero Head Module using ‘Sensor’ menu on rero Controller. Connect the Head Module to rero controller
then go into Sensor Menu, select the ID of Head Module in the list of sensors. There are 3 features can be tested,
namely the sound sensor, IR sensor and RGB LEDs. The sound sensor value and IR sensor value is display as
scrolling bar with the value that varies from 0 to 255 depending on the surrounding sound level or the reflected IR
rays. There are 3 check boxes to turn on or off the RGB LEDs colours. User can turn on or off single or mutiple color
by checking the check boxes.

13
Head IR sensor
IR sensor is located infront of the Head Module above the eyes. IR sensor is used for trigger the robot to start when
user wave their hand infront the face of robot.
Head Sound Sensor (Microphone)
Microphone is located inside of the Head Module and it is invisible from outside. Microphone can be used to detect
maximum sound volume, trigger robot to start by hand claps.
It has features of capturing maximum sound level detection, hand clap counter and current sound volume level.
Sound volume is sampled at sampling frequency of 3.9KHz. User can set threshold level for the hand clap detection.
Hand clap detection is done at interval of 800 miliseconds. This means that, when a clap has been detected, the
sensor will ignore any claps within the 800 miliseconds, sensor will only detect for second clap after 800 miliseconds.
This to prevent a single clap being detected as multiple claps.

Head Eyes (RGB LEDs)
By default the eye will light on with white color when powered on. User can set different colour to the eye to give
beautiful outlook to the Head Module. Eyes are composed 2 RGB LEDs, the color of the eyes are based on 8 bit RGB
true colour set by user. User can utilize the to display different status of their robots too.
For advanced user: Internally the eyes are used by Head module to notify user of certain information too. Eyes will
blink in red colour for 4 times if user call a reset factory defaults to the Head Module. If user set alarm LED to on, the
eyes will blink when there is error packet received (range error, checksum error or instruction error).

3.1.4 rero Infrared Sensor (RR-IS-01)
Infrared Sensor Physical Appearance
rero Infared Sensor is an easy to use sensor which detects obstacle and proximity. When powered on the LED will
be lighted on in blue color as power indicator.
By default the Red LED indicator of the rero IR sensor is off. User can change the LED register of the control register to make it
when the sensor detects obstacle, the red LED will light on. The IR sensor can detect a white surface obstacle up to maximum
30cm.

17
rero IR sensor has auto calibration function to calibrate the sensor detection threshold to the surface that it will operate.
User can test rero IR sensor using the rero Controller ‘Sensors’ menu. Connect the IR Sensor to rero Controller, then go into
Sensor Menu. Select the rero IR sensor ID to display the IR values. The IR sensor values is display as scrolling bar with numeric
value from 0 to 255 depending on the reflected IR ray intensity.
