Let's Make Robots!

Zombie Challenge



And the Winner is... Drum roll.  Jad- Berro with Vario


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. 
  • If you have questions post a comment

Sorry there is no prize this is just purelly for fun. You will recieve lmr bragging rights and an E- Five. Good luck! Now start making your robot.

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

The possibility is high :)

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

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?

Sorry, that is not the schematics. I need a diagram of the parts that shows what component connects to the other componetnt. Mark the type of transistor and label the leads and anyother part. Use the ground symbol for the negative. Thanks I would really appreciate it. So if you put that in u will be winning. Other LMRers, STEP IT UP!

Is a relay a logic component?
