I just ran into this balancing bot kit. Kinda pricey but cool that you can get one.
(Can we get some samples?)
Now, you can build your balbot using this kit instead of starting from scratch!
The BalBot Advanced kit includes everything the Basic kit does, PLUS the BrainBoard microcontroller board, 2 forward-looking infrared distance sensors, a programmer, serial cable, C-compiler, and more (see kit contents below for details)!
In short, the BalBot Advanced kit includes all the parts* you need to build a fully autonomous, self-balancing robot! It also includes everything you need to write your own custom C code, and program the bot with it. Programming skills are required to develop your own robot behaviors, or to add on accessories. Basic assembly skills are required. Soldering is NOT required.
Now you can buy balancing-bot kits
