A new iOS and Android programmable building block educational toy called Knight Truck is launching for $69 these days: https://www.gearbest.com/block-toys/pp_009111968696.html
There are a few versions of these toys that can be used as a pre-introduction to robot technologies. But this one would go great with an iPad or Android tablet as there are quite a lot of options for creating routines and apps for it.
And just like you can control some drones with gravity sensors in a tablet, you can use the gravity sensor in your tablet to control the toy vehicle here too.
Or you can preprogram it with a long list of instructions, like setting the speed, when to turn, and commands like that. The battery capacity is only 220 mAh though, so the runtime is described as just 15 minutes long, and the range seems short too.
