Meet the Armz: a smart toy system with a modular design that combines with your iOS/Android device to provide your kids with an interactive playing experience. It has a core module and a bunch of arm accessories. You can use the RC wheel, Sumo arm, caterpillar, and Slip wheel to play on the floor or table.
The Armz app gives you access to 4 different modes (Tank, RC Car, Arms, and Sensor). The toy uses sensors to measure its position, tilt, and impact absorption at all times. This smart toy system is expected to ship in August.
