Write an Android application

Need a car simulator. The user interface (car controls) remains on the android mobile device. The computation engine for simulating the Physics of the car should be implemented on the RaspberryPi 3. The Mobile Device and the RPi for a single car should be connected by USB. There should 3 cars controlled by 3 people on 3 android devices and will drive on the same track together (Multiplayer simulator). Each person should be able to see ALL the cars, and know their positions dynamically. Information about the mechanics for a particular car resides with the corresponding RPi, but all the RPis in the same WiFi network will have to communicate with each other and dynamically exchange information about their cars in REAL TIME. This information will be used by all the cars to know relevant details about the other cars. Driving should be implemented in 2 modes: City Driving Mode: where the RPi’s will exchange information with each other, and if needed, override the control signals from their respective drivers to ensure that the cars do not crash. Racing Mode: where the control signals from the drivers override the safe autonomous driving if needed. Project deliverables: .apk for car control and all files executing on RPi Milestone will be released after 100% completion of work and after checking the working.
