Battery Ball
The power supply module of Mabot.
• The micro-USB supports a device charging function;
• Battery indicator lights on both sides of the charging port;
• Every battery ball has four ports, on each side of the ball.
Battery parameters:
• Typical capacity: 640mAh;
• Standard voltage: 7.4V;
• Recommended charge temperature: room temperature
Instruction to the switch:
• When the Mabot is off, press and hold the power-on button for 2
second to boot up; the indicator light of the battery ball will turn
on;
• When the Mabot is on, press and hold the button for 3 seconds
to shut it down; the indicator light of the battery ball will turn off.
Instructions for the indicator lights of the battery ball:
• When the light is green, it means that the battery ball is near full
charge;
• When a red indicator light appears, it means that the battery is
low;
• When the battery ball is low on power, certain modules of the
Mabot may become unresponsive;
• The battery ball will show a blue light while charging. A green
light means it is fully charged.
Attention:
· Never use a damaged battery ball;
· Never insert any sharp metal into the connectors, as it may
cause short circuiting or permanent damage;
· Keep the battery ball off when not in use. Please charge and
check the battery ball every fourth months to keep in working
condition.
· Please use under adult supervision. Remove the charger
immediately after charging has completed.
· The battery ball can be turned on while charging. Shutting
the device down before charging is suggested for extended
times.
Charge and general instructions:
• Service time — the more power-hungry devices connected to a
single battery ball (such as rotate joint ball, swing joint ball, drive
ball), the shorter amount of time it will operate.
(e.g. When the Mabot starter robot runs continuously at its
highest rate with the control ball and drive ball lights on, the
battery ball can continue working for around 50 minutes.)
• Charging time—It usually takes two hours to fully charge. The
time spent varies based on power adapter standards (5V and 1A
power adapters are recommended).

Color Sensor
It can detect the color and intensity of light.
• Colors options:
• Levels of light: 0 (extremely dark) to 100 (extremely bright);
• Detection angle: the lamp head is perpendicular to the object
• Detection distance: 1 cm;
• Each color sensing ball has one port.
Mode instructions: Three status of color sensing ball:
• Color mode: When lamp base is white, it catches the color detected by the color
sensing ball sensor.
• Reflected light intensity mode: When lamp base turns red ,it measures reflected
light’s intensity from the objects exposed to it;
• Environmental light intensity mode: When lamp base turns off, it can measure the
light intensity of environmental light through the sensor.
• When in color mode or reflected light intensity mode, make sure the color sensing
ball is at a right angle and is not touching the surface of the object being detected
(e.g.: a line-tracking robot from the package).
Attention:
· Please do not smear or paste things onto the lamp or it will
compromise the detector’s sensitivity.
· Mirror and dark colored objects will compromise the detec-
tor’s normal status.
· The parameters above are for reference only. Do not stare at
the lamp for extended periods.
It can detect if there is any obstacle ahead.
• Angle of detection: The lamp head and object are perpendicu-
lar.
• It can measure distances using infrared light, measuring
between 5~15cm (the parameter is based in the test results done
on a white A4 piece of paper);
• Each infrared sensing ball has one input.
Attention:
· Please do not smear or paste things onto the black cover or
it will compromise the detector’s sensitivity.
· Mirror and dark colored objects will compromise the detec-
tor’s ability to operate.
· The parameters are for reference only.

Data Cord
Communication cord is for signal transmission between modules only, not for electric current trans-
mission.
How to use it: When a majority modules are power-consuming (such as rotate joint ball, swing joint ball,
drive ball) in the Mabot, the exported electric current from one single battery ball may not meet the power
requirement, so one needs to group power-consuming modules with different battery balls for respective
power supply. The communication cord can transmit commanding signals between multiple battery packs.
Power Cord
Power cord is for transmission of both electrical current and signal.
