7. Building a Wireless Remote Control
Bioloid supports two types of wireless communication. With these methods, user
can control the robots remotely or allow the Bioloids to send and receive the
data between each others.
The first method involves sending data using IR (infrared rays) transmitter-
receiver function of AX-S1 and by attaching the Zigbee module ZIG-100, dedicated
Bioloid wireless device, to CM-5. With this attachment, Bioloid can communicate
via RF method.
7-1. Infrared Communication Program Using the AX-S1
IR Communication
In AX-S1, there is a transmitter-receiver built-in that allows IR communication.
Although IR communication is often used for short distance, as it is strongly
influenced by the direction and the location of its devices, users have to keep in
mind of above limitation when transmitting. As the images below show, IR can
send data in three directions, only one direction is allowed in receiving data.

IR Communication H/W
It is the sensor module AX-S1, rather than the CM-5, central control device of
Bioloid, that actually handles the communication. To communicate via infrared,
you need at least two AX-S1s and two CM-5s.
