Arduino Wireless SD Shield

Projects General Guidance

Hi, i'm Fabio and i'm working on a mobile robot project.
Into the robot there is an Arduino Mega 2560 connected to a Wireless SD Shield with an xBee module (receiver).
On the other hand there is my computer connected to another xBee module (transmitter).
I have to do these two operations:

  1. Transmit data from my computer to Arduino:
    I should set the on-board switch present in Wireless SD Shield in Micro position.

  2. Load a new sketch into Arduino:
    I should connect Arduino to my computer via USB and i should set that switch in USB position.

So,
knowing that the robot has a closed structure that contains Arduino and the Shield, and that there is an external panel that allows only the USB connection with Arduino,
my question is:
Is it possible to perform the two operations mentioned above (without acting on the switch) ?
Thank you in advance for your help.

No. That's why you need the switch.
