I'm currently doing a project at university looking into adapting V2V communications and sensors to a scaled down version involving two RC cars (~30cm) that are aware of each others position in order to simulate the concept. I was wondering what the best way of communication would be between them, focusing on predicting positions and reacting to that through a control system.
I've looked into a GPS system whereby a rough position is monitored and sent to the other car, perhaps through a Bluetooth module? Would this be adequate or is there a better alternative for this?
Also, one of the cars would have ultrasonic sensors in order to react to the immediate environment, could this in anyway be used to feedback to predicting their positions?
