The RX Bridge upgrades your ArbotiX RoboController from an AX-12 controller to an Dynamixel
DX/RX/EX controller. This add-on board converts your existing ArbotiX Robocontroller TTL serial port
into an RS-485 serial protocol.
The RX-Bridge answers the call for a high end, fully programmable controller for the higher end
range of Dynamixels at a much lower pricepoint than other less-capable controllers on the market.
NOTE: Your PyPose/NUKE install must be version 0013 or higher to support the RX bridge. PyPose/NUKE
currently does not support the higher resolution of EX servos (version 0014 will)
Software
Enabling use of DX/RX/EX series servos in the existing ArbotiX software is extremely simple; just a single line of code needs to be added to your program. Your existing AX-12 based project can easily be scaled up to using the more powerful higher end Dynamixels, with few if any modifications needing to be made.
- BioloidController - this is a Bioloid bus library for use with the Arduino environment. It allows easy manipulation of poses, the storage of poses in FLASH, and full interaction with AX-12 servos.
- PyPose - this is the stock pose & capture software. Written in Python, uses pySerial to communicate with an arbotiX board running the pypose sketch. After you have done pose and capture, PyPose can automatically create a C header file with the poses ready to load with the Bioloid Library.
- Other Libraries - there are several other, smaller, libraries that have been made to make using the ArbotiX extremely easy.

Frequently Asked Questions
Q: Can my ArbotiX control RX and AX servos at the same time?
A: No, the RX bridge converts your ArbotiX into an RX controller, when using the RX Bridge,
the AX servo ports will be disabled.
