This is my first entry in letsmakerobots.com but not my first robot. I wanted to make a robot with a pcb as chassi, like 3pi, but I wanted to be able and take the microcontroller and use in other projects. I also wanted the mindcontroller to be an Arduino series mindcontroller. This is the prototype and I hope one day I will print a pcb for it. These are the componed I used for the robot :

  • 1 x Arduino Nano
  • 2 x 30:1 Mini Metal Gear Motors
  • 1 x Pololu 1/2" Metal Ball Caster
  • 1 x L293DNE
  • 1 x Lcd 16x2
  • 1 x 74HC595 shift register
  • 1 x buzzer
  • 1 x 7805 voltage regulator
  • 3 x CNY70
  • 3 x led
  • 1 x ir receiver

Its functions will be linefollowing, maze solving, remote control with ir and maybe I will mount a servo with a sharp ir sensor for autonomous navigation. When I will finish programming I will post a video and the code.




The new battery is here ( 7.4 volts lipo 850 mah) so I made a small video using a very simple code.

I like the idea of a PCB chassis alot. Good thinking

Good idea but be careful of flexing. It can crack the solder joints or even lift the pads off the board.

Hope you will add the rest of your bots too.
