Remote Control of InMoov

I have now a movable base for my Marvin. I control my bot with MRL and an odroid xu4 but it requires a 4A 5V power source.

I know some of you use a tablet PC which has its own battery.

Thought about using a wireless connection of my main PC (W10) with the 2 Arduinos.

Anybody running such a configuration and what devices are you using?
