Mario Bambagini / Mbed 2 deprecated rover_car

This project aims at hacking a remote controlled car by replacing the tx/rx and navigation systems. This project implements the car side.

Dependencies:   mbed-rtos mbed ssWi

This project consists of a remote controller which pilots a car holding a video camera onboard. It is divided in two main parts:

  • user side: the microcontroller reads the user input from the joystick (four potentiometers), elaborates them and then sends those commands through the wireless connection (using a XBee module);
  • car side: the microcontroller receives the sent commands (using a XBee module), elaborates them and adjusts the main engine, the steering servomotor and the two servos which move the X-Y axis of the onboard video camera.

Here are a image of the hardware and a video I recorderd and edited. http://www.mario-bambagini.it/web/sections/software/car.jpg

Concerning the part related to the user side, the project is the following.

Import programrover_pc

Last commit 12 Mar 2013 by Mario Bambagini

The communication protocol I exploited to make the two parts communicate each other is ssWi.

Import libraryssWi

A simple wireless protocol to let my examples communicate each other. ssWi stands for Shared Slotted Wireless protocol
