MARS SmartCar

This was a second term project thar we did in the program that I am a student in which is the software engineering and management program in Gothenburg University. The purpose of the project was to bulid a prototype of an embedded system in the for of a arduino smartcar. We decided to allso use a raspberry Pi with a camera module as well. We also developed a Android app for controlling the car. The main features that we implemented is the remote controller app that has the ability to control the smartcar by using a virtual joystick or on screen buttons, it can also display video in the background of the app at the same time as controlling the car. On the screen there is also a secondary joystick that is used for contrlling the pan/tilt functionality for the camera mounted on the car. We also implemented a radar feature which uses the onboard ultrasonic sensor to scan the environment in front of the car and display obstacles as red dots on the screen. We also tried to make a mapping feature where the car could automaticly drive around and create a map of it's environment but due to inaccuracy in the motors that we used we were not able to fully implement this feature. The source code for this project can be found on this Github page. You can also check out the video here below to see the app and car in action.
