There is world outside of Raspberry Pi. You can always buy the MSP430 with IC's in DIP package. Burn one of the GPIO's, no problem. Remove the IC from the DIP and a put a new one costing really really less.($1 or $2) I suppose. Buy a cartridge of them and you are good to go. You can blink LED's, write your own baremetal OS etc. The tools are also good with gnu tools also available.
I am kind of OK with kids solving something using iPad etc but don't you think at her age she should be building/solving something with her hands? What I believe is that using a pen and paper would help them build/solve a lot more better than using a some gadget. The problem solving boundaries are always stuck inside what the application/device can do.
From my own experience even now doodling something on paper helps me clear my doubts rather than sitting in front of VIM. As I am a visual learner I tend to draw abstract topics which helps me think clearly.
You need to get a clue on microcontrollers and CPU's. There are plethora of 32 bit microcontroller robots and drones available in the market. You can control a drone using a simple MSP430/MSP432 and conserve as much power as possible.
When you say ARM draws higher power what do you mean? It does not depend only on the instruction set. It also depends upon the process behind the manufacturing of the microcontrollers. Currently ARM microcontrollers from TI are the lowest power i.e. the MSP432 line ARM Cortex M4 MCU's in the market.
The guy does not know the difference between Microcontrollers and CPU's. M3 and M4 does not have an MMU and multi stage pipelines. I really don't understand how he is doing drone software without knowing the controller internals.
Why would you want to use a full blow CPU instead of a microcontroller. ARM Cortex M are microcontroller series. Comparing a MCU and CPU is apples and oranges.
