We're currently finishing our T-shirt launching robot, and would like the OI to be portable. We're using the 2004 control system.
Basically, I need a way to power the OI with a robot battery. Has anyone done this? If not, does anyone know how this might be done?
Possible methods (in my mind):
1. Find documentation stating the OI can be run off a battery (not regulated 12v)
2. Use a DC-DC converter ($$$

)
3. Wire up an additional robot controller, and only connect the power lines (again, I'd need documentation.)
Thank you.
