Simple Robot project for children

[somenerd]

Right after my finals, I will be flying to the Philippines for an engineering service trip in Manila (think building houses, helping out the locals etc). We will be interacting with a lot of children, and the group leader wishes to build some kind of robot for the kids to play with.
Any basic kit suggestions? Something that doesn't require too much programming would be a plus, although a programming requirement wouldn't be a big problem. There will be some children available to translate, but I doubt most of the kids we will interact with will know english, so something relatively intuitive would be a plus.
