Introduction

The RX Bridge is an ArbotiX add-on board that enables control of DX/RX/EX series servos.

Setup

1. Remove jumper J1 from your ArbotiX to decouple the rx and tx lines of the serial port.
2. Plug the RX-Bbridge into the ArbotiX. The outer 3-pin header plugs into the row of pins marked S1, which previously were jumpered with J1
3. Use the standoff to connect the RX-Bridge securely

Software

To enable support for the RX servos, we need to edit our BioloidController library just a bit. Open ax12.h, found in the Bioloid folder of your Arduino Libraries folder, and uncomment the line near the top that says #define ARBOTIX_WITH_RX:

#ifndef ax12_h
#define ax12_h

// Select the appropriate board for configuration
//#define ARBOTIX
#define ARBOTIX_WITH_RX

#define AX12_MAX_SERVOS             18

That's it! You're now setup to use RX servos just like you used to use AX servos with your ArbotiX.

Note: EX servos have a 12-bit range, not a 10-bit range, PyPose 0014 does not yet have support for a 12-bit range
