Let's Make Robots!

Welcome to The Toy Challenge

Now you can both make your first robot, AND win a price!

You are also very welcome to join in, if this is not your first robot.


  • Find any old (or new & cheap) toy.
  • Rip out it´s guts! (just the electronics - but leave motors, lights, sensors etc it might have)
  • Insert your brain! (well - not your own, a microcontroller)
  • Add sensors!
  • Code, test and have fun!
  • Film the result at some point, and enter it on letsmakerobots.com!

- It is an extremely fun beginners-challenge to just take a cheap RC-car / boat / tractor / plane? .. etc, and make it autonomous.

All you need could be:

If you go for the Picaxe, this board might have your interest as it can take a little more power


Toy must show ability to perform task autonomous. That is - to put it simple; if it was an RC-car, it should be a car that drives around by itself!

There are bonus and street-credit for extras, fun and coolness! And also provide us pictures if you are a nice person!

If we ever get 3 such robots in here on letsmakerobots.com, they will get extra focus for one month, and the one voted highest for by all visitors will win.

If we never get enough admissions, or if you do not win, "braining" an old toy is still one of the best ways to get started!! (and fun too)


One (cheap) RC-car or other toy of editors choice, send to you by mail. (so you can give it to your brother if he was not happy with you for spoiling he´s toy)


I am hoping to see your entry!
