In this project, we implemented smart car control with android application. Phone A is together with the smart car, Phone B is in the controller's hand. Phone B send instructions to Phone A through WiFi, then Phone A send instructions to the lauchpad through Bluetooth. We can send instructions on Phone B with gestures, voices, buttons and gravity sensor, and Phone A can send back the images took on the car at the same time.
