wireless Synchronous Robot project

Hi so i'm currently developing a Synchronous robot wirelessly for a university project. I have tried with Hc-05 bluetooth and I cant seem to make it synchronous only to find out that its not possible for this bluetooth module.

I want to ask some suggestion for bluetooth module that is compatible with arduino that is also able to do one master and multiple slave concept. I have looked at nRF51822 and nRF51422 as both possible solution to my problem but im not entirely sure if this is the best option for my project.

Any suggestion for this problem would be great!

Edit: Also forgot to mention, i got a dynamixal shield and code ready to be able to move the robot. Im just stuck with the wireless bit as to how to make it synchronous.

You also forgot to tell us what a synchronous robot is and why you need it.
