Thank you, everyone, for your input. I have been leaning more and more towards using 4-1kW servo motors. Partly because of their size but also, because they automatically have an encoder which will help with the feedback adjustments to help the platform correct itself. My only problem is that I am not sure what the best way would be to run these 4 servo motors off of batteries. Most of my experience with motor controllers has been dealing with VFDs that run AC Induction motors that require an AC input power which then runs to a rectifier, then to an inverter, then to the motors. I know there are VFDs that can simply take a DC input voltage and go straight to an inverter but I'm not sure about servo motor controllers. I will continue researching this but any advice on the matter would be appreciated. Thank you for your quick replies.
