The good news is that the BigTrak is in fact runnning on its own, avoiding obstacles with its three IR sensors. The bad news is that I have discarded the Raspberry Pi for this project. The vehicle is controlled by an Arduino mini now and there won’t be a Raspberry Pi in it in the near future. Now why this?
- I fell in love with the BigTrak and I simply can’t make any more holes in it, let alone ripping the keyboard off
- My plan to decrease the speed gradually as obstacles are detected does not work. There is not enough torque to move the wheels when the speed goes below 60% (and that is still too fast indoors, at least at my home)
- With the vehicle moving that fast a video camera is obsolete, one wouldn’t get a clear picture of anything (and I don’t have pets to annoy…)
So I am going to share the last steps in making this project. This involves mounting the sensors and putting everything together and the simple, yet working, code for making the BigTrak drive. Continue reading
