Let's Make Robots!


raspberry pi arduino,

So im pretty newish to robotics and programming in general, but ive done some reading and have started down my own path.

my robot(including a picture, description, wiring diagram and code) is posted here http://letsmakerobots.com/node/40350

2WD Robot, ArduinoMega 1280, PanPing sensor problem

Hello everybody. 

First sorry for my English but not good. I want to ask the profis about my robotics problems. :) 
I have a 2wd mobile platform. I played with this so many and my old simple codes was working well. 

But I decided, I want to upgrade a little bit my "stupid" code which was very good with the fixed ping sensor and some IR sensor but too simple. Than I rebuilded all IR sensor first, and builded a little servo for the PING sensor.

Kinda stuck again

OK I have re-writen my code and now I am having a problem where my left side motors are not being driven.I know it is not a hardware problem. I upload an older version of code with out the scanning portion and everthing works.I have included LEDS on the proto board to see if I am getting comands from my uC and right side is working but not getting anything for the left. the new code is basicly an addition to the old. I just added the servo and varibles so it can look left and right.

Area mapping

I have (that is relative because I have not yet ordered my first parts from Robotshop) a PING ultrasonic sensor. I'll be having an arduino mini - though I'll no doubt buy something bigger after - and I wonder if I can efficiently make my upcoming rover (differentially driven, nothing special really) map it's surrounding area using a grid. Is it possible or will I run short on memory with the arduino mini? And more importantly, I need help with the code (I have 0 experience with code, though I have enough theory I guess...). Any suggestions are appreciated.

PING sensor question

Oh hello there! I'm pretty new with robotics and all of that exciting stuff. I'd been wanting a microcontroller for a few years, and when mbed gave out free mbeds, (yay) I got one and messed around with it a bit.
