This first one is called an Adventure Bot. Well it's like a puppy on wheels. If you place your hand near its head, it follows the hand. If your hand is too near its head, it goes backwards so as not to hit it. And this comes with background sounds too. The four sets of sensors below (around its mainboard) could be programmed either for obstacle avoidance or for edge detection. Yup the latter programming makes this baby detects the edges of the table so she doesn't fall off.
This other one is the i-Racer. It's basically a toy car like those RC ones. But instead of a Remote Controller, you use an Android apps from your smartphone to play around with it.
