And here is your fabulous prizes

LMR bragging Rights.

and an E-5. place hand on the screen where hand is to recieve your E-5


This is a contest where you may not use any microcontrollers or Ic chips. This may or not be challenging. You can make the robot do anything you wish (example= Line following, obstacle avoidance) The sky is the limit, as long as you follow these rules.


I have gave all LMR members more time to enter.


  • You may not copy anything you see in LMR this includes even your previous robots.
  • You can't use things from internet, however you may modify the schematics you find online.
  • You must make it
  • No IC/logic chips
  • No Microcontolers


  • You must show your circuit schematics.
  • List your parts.
  • You may list the cost.
  • Create a blog with picture(s) and video(s) then post the link in comments.

I have a robot made myself... I saw a schematic with LDR and LED... but I replaced them with QRD:.. I submitted my robot last week... Why I can't show it off?

Your schematics did not show the components. I would like to see the design with the components labeled exactly. Also I would like to see the transistor labeled. And the exact ohms of any resistors and battery voltage. So far I think it is simply amazing!

100k varistor

any NPN transistor

any photo transistor 

330 ohm for the led


done ;)

Ok thanks

E-5 recieved :) , are you going to make one !?

The possibility is high :)
