Introduction So I've trying now for a few weeks to have my rock crawler, named Sputnik, be autonomous. The goal is that it should be able to avoide any objects on its path, and while looking around, it should record data on a SD card such as Temperature, Humidity, Light Intensity, Atmosphere Pressure (more to come).

Sputnik - IR / Unltrasonic autonomous vehicle

Introduction

So I've trying now for a few weeks to have my rock crawler, named Sputnik, be autonomous. The goal is that it should be able to avoide any objects on its path, and while looking around, it should record data on a SD card such as Temperature, Humidity, Light Intensity, Atmosphere Pressure (more to come).

Second is that it can overrided to be manually operated with xbee and a logitech joystick, directly from my mackbook.

Done so far

The structure is finaly finished, it took me a long time to finish the Rock Crawler mainly because of having the wrong tools and not enough time. Once the structure was finished I moved on to the electrical componants and programming part of it. I am completly new to Arduino, so I spend lots of time looking around on the web on what could be done and how.

The structure is finished, the crawler is done, and a plexiglass body is fixed on top, housing all my elelctronics. I will publish pictures later.
