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


 

 

 

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).

I forgot to thank Rodrigo Forrequi for his fantastic GUI (one of my sources of inspiration). :)

Muy bien ! Waiting for your second robot !

 

Very nice for a first bot. More thinking than I have put in to any bots that I have considered constructing.

Wow, this is a great robot. And this is your frst robot? Can't believe it. Very clever designed. Damn small without using of SMD parts.

Very nice! Cool robot.

Where did you order the PCB?

Thanks

Hi all,

Last summer n00b0t was upgraded to 1.20:

Very nice job for your first robot.

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!
