**4 channel motor shield & robot control (DX8 or Ipad/Wifi) **
The first decisions are taken. This afternoon I ordered the Nexus Robot mecanum wheels and the motors suggested by Duane ( Pololu 12V DC , 150 rpm , 67:1 metal gearbox and an integrated quadrature encoder ) .

I am going to use an Arduino microcontroller. If I know better what functionality I want to make I decide on the type ( Uno , Due or Mega ). Now I am thinking about the motor shield and the robot controller.
For my first robot (Rover) I used two 2A Motor Shields of Dfrobot . Worked fine , but two shields . For my new robot I consider the Dagu 4 channel motor controller. Good choice? What can you recommend me?
For my first robot I made a remote ( APC220 + Arduino joystick + Arduino Pro) . For the new robot I doubt between:
- Spectrum DX8 + AR8000 receiver ( I now use for my quadcopter ) .
- Ipad using wifi connection
What are your thoughts on this? Or should I keep it simple and start with my current remote and try to master mecanum control first?
Thanks in advance.
