Here is a RC car that you can control with simple hand gestures thanks to a wristband. The Ultigesture Gesture-Controlled Smart Car also has smartphone control, so you can tilt your phone to steer it. You can switch between modes easily. The cars are made of ABS plastics and will be shock resistant.
The smart wristband has an ARM Cortex M4F with 9-DoF IMU, Bluetooth, and 5 LED lights to indicate battery level. Like what you see? More info is available here.
