My First attempt at a robot, basically the LMR start here bot hacked out of a BigTrak Jr.
If I added on all the time researching to the build time it would be HUGE, lol. Learn't alot tho.
Next I'd like to try sort out the drifting / wheel spin problem it has.
And then try some Wall following / Maze solving. Any Hints?
I've include my code as well, for anyone who wants to modify (or see if there's anything wrong with it)
UPDATE 16/12/11
I got my BigTrak to wall follow as well, at the moment it's two set's of code but I'd like to make a button menu at some stage.
It uses a rolling Average from the IR sensor to sort out the gitters (random readings) and a Last Command variable to stop sending to many repeat commands to the motor controller.
Code is uploaded in ZIP's as LMR won't let me upload INO files yet :-) Arduino's new file type.
Next Up, Maze Solving / Shortest route finding, or Maybe Line Following.
And I don't think this robot is ever going to be completed, He'll just keep growing (until I run out of memory anyway)
Navigate around using an IR Rangefinder
- Actuators / output devices: Pololu dual serial motor controller, 2 DC motors from the toy
- Control method: autonomous
- CPU: arduino uno
- Sensors / input devices: SHARP IR sensor
