Hi All,
Five months ago I decided to make a small and simple line follower. It would be my very first robot, and I had to learn from the basis. Five months later, n00b0t is running, and I'm happy to share it with you.
DESIGN
Initially I thought to make an Arduino controlled bot, but I decided to go a step further including on-board micro. Since I wanted to keep the size small, it was quite difficult to find the right design...
But I finally found the ideal shape:
PROTOTYPE
LAYOUT
PCB
v1.00
v1.20
Changes from v 1.00
- Added voltage divider (R10/R11) connected to A0
- Added TSOP connected to D2
- Included two new LEDS connected to D3 and D4 (while maintaining the connection pins)
- Added of 5V & GND pins
- Added an external battery connector
- ON and LN jumpers relocated
- New buzzer package (supporting multiple models) and slightly relocated
- CNY70 turned 90º
- General components renaming
- Ground plates Isolate grown to 12 mil
- Isolated holes in ground planes in contact positions with nut / screws
Now I think the project is finished, so I'm sharing source files as OSHW (under CC-BY-SA license).
If interested, you cand download them from the project blog site: n00b0t.tikitake.com.

Motors
Hi
Amazing job man, it looks like it would definitly kick some butt at some competitions. I am also making a line follower. Could you tell me what the gear ratio is on those motors?

Hi,
I've tested with 56:1 & 30:1.

Updates
Hi all,
Just to say I've updated n00b0t site with several sketches and new 1.20 media.

Wow, I love the super clean
Wow, I love the super clean one board design! What kind of projects do you normally do? Also two questions : What is the reason for the sensors just in front of the wheels? And it looks like you have Pololu motors what ratio are those?
Thanks Very impressive!

Hi,
The side sensors are designed to detect turn signals/markers (they are quite common in european competitions):
Regarding motors, you could use any 12mm Sanyo 12GN NAXX type micromotor you want (not only Pololu ones). I bought the 56.8:1 ones here.
BTW, thank you everybody for your comments!

Not only is the robot great,
Not only is the robot great, but you lay tape down like a mastah!

Hahaha!
That's not tape, but a plotted CorelDraw design. :)
BTW, here you have a couple of them (in PDF):

Wow really cool
Very good for a first robot and it is running so smoothly!
I wish mine could go that fast and be that realiable...
Thumbs up!
