YOo may also wish to provide more details about qtpi mega blocks.....

Qtpi is a toy manufacturer in India that makes robot kits. Supposedly App Inventor can be used to program them. I cannot find any documentation anywhere about how to use App Inventor to program their robots which are similar to Leggo Mindstorms.
