How to control posisition of 2 Dynamixel ax12a with different degree

If you are going to use SyncWrite for AX-12, you can also use the example code I wrote for XL-320s at this post:

There are two programming differences between XL-320 and AX-12 which are:

  1. The Present Position Address on the AX-12A is 36, while it is 37 on the XL-320.

  2. The AX-12A does not have a P Gain Parameter.

Make sure you read and understand the Control Tables of XL-320 and AX-12
