What's the best robot to introduce a nine-year-old girl to programming and robotics?

I am a quadriplegic grandfather and I want to introduce my excited and bright nine-year-old granddaughter to the world of programming and robotics. She loves computers and even somehow hacked the school computer so it logged more math hours than she had actually done to win a contest – yikes! Something fun, ambitious, but doable for the two of us in an afternoon. Something she can show off to her siblings and friends and under $100.

    This is a little bit above your budget, but it's worth taking a look at. Sparki is an open source Arduino-based bot that uses block-based programming to help your granddaughter get started, and then she'll be able to move onto learning C/C++ after she gets her feet wet.

    It's a robot she can program herself, in Croatia kids love it! - first batch is sold out but you can register to preorder new ones.
