    What are the + and - 's of these two platforms.

    Which do you recommed for applications that you are familiar with?

    Personally , I eventually would like to be able to control rc cars planes via remote pc or android over the internet.

    I understand the languages are not the same +- , and one costs more....that's about all I know so far.

    What are your projects (ones you've completed , currently in) ?

    I would not attempt to compare Arduino with Raspberry Pi. There is a world of difference between the two.

    For RC, especially planes, quadcopters or drones, I would use neither. Too heavy.

    If you are now starting out learning about microcontrollers, get the Arduino and learn the ropes.

    For RC, I would roll my own using light weight ultra low power chips.

    What would be the point of using ultra low power chips when the power taken up by a micro is going to be << 1% of the energy taken up by the power electronics eg. propulsion etc?

    Real-time control would be next to impossible because of the unpredictable signal propagation delays over the Internet :(.

    Hi,

    I am working on Raspberry Pi - B. I have to connect it to a AC Servo Motor Yaskawa 10C3C11.
    I will have the following connections:

    Rasp Pi ---- DC to DC booster ( 5 volts to 12 volts) ------ DC to AC inverter (12 volts DC to 110 Volts AC) ---- AC Servo motor.

    I have to order the Booster and Inverter, what speifications would be important?

    PS: I am sending PWM control signal from Pi to Motor

    Schitale, you have hijacked someone else's thread.

    Internet delays aren't so bad, it depends on the definition of "control". If the unit is semi-autonomous, then the impact of delays are greatly mitigated. The Mars Rovers have substantial propagation delays, as do the drones in the news.

    Are they really controlled via the internet? I would have thought military comms channels, with predictable propagation delays, would be used.

    No, I mean that the Internet delays can't be any slower than sending a signal to Mars (minutes of delay) or that semi-autonomous allows a sort of fail-safe in case there are propagation delays on drones.
