Let's Make Robots!

Cross the gap.

Winners as voted on by my family as follows below:


Game: Cross the gap.

Objective: Build an autonomous robot that starts completely within a 12 inch by 12 inch by 12 inch square box.

It must then cross a 12 inch gap and stop on the other side without any part of the robot touching the start side when done.

In order to win you must show a video of your robot completing this task, show the robot measurements and gap measurements in the video, and include the LMR logo on the video.

Fastest time to do so, and meet these constraints wins. Timing will start when the robot leaves the start box till its on the second table and not touching the start table. In the event of a tie, or controversy, public vote will decide a winner.


Prize for fastest completion goes to:   antonio.caciuc

  • Freescale 68HC11 microcontroller, 32KB Flash RAM, RS232 serial port programming interface, 2-line by 16-character LCD, Piezo buzzer for sound, 4x DC motor ports, 6x servo motor ports, 9x Digital inputs, 8x Digital outputs, 21x Analog inputs, w/ Interactive C software and code examples.
  • a pair of new metal gear motors
  • some assorted sensors - new unused.




Prize for the robot I find most interesting goes to: Kelpy (I was close to picking the NXT entry, but really liked the fabrication.)

  • A new Parallax Basic Stamp controller, product details can be found on their website, w/ software, cable, tiny breadboard.
  • 1 new unused servo, 1 used servo of same brand.
  • some assorted sensors - new unused.


Prize my family voted for most interesting:    sebathorus  (the first event entry)

What did you win? You will find out soon enough.



I am emailing the winners to send them their prizes. So winners check your inbox.

I was planning to write a more elaborate "thank you" note but I have been very busy lately so I will just get it out now, while the challenge is still somewhat fresh.

I would like to thank the organizer for putting togather a great challenge and offering all the cool prizes. I would also like to thank the other participants, their work motivated and inspired me.

I am actually not that proud of my winning robot, I think NXTreme's robot was probably as fast as mine if not faster. I do not feel too bad about it though, because I have since built three more gap crossing robots. Unfortunately, I did not have enough time to complete and post them. I built the last two versions in my hotel room and I took some pictures, so I should have enough material to create a robot post (sometimes during the weekend). The new design is much simpler and much faster. ( here is a sneak preview http://www.youtube.com/watch?v=6afecq-Aoek )

I am thinking of sponsoring a new challenge with the same level of difficulty. I hope this one will draw even more participants. 

Thanks again for the opportunity to make some robots!


I'm going to make a new challenge at the end of this year as well.

My new game will be called "Stacks". You'll have to autonomously move and stack objects to win.

I had planned to use my Mr Tidy to enter "Gap", but switched to working on my new game.

As the making a challenge rules state you can't make a game that you can't solve yourself.

So after I solve the game, then I'll be able to post the new game.


On a personal note:

You guys wouldn't know this, but I run a charity here in the US.

The prizes you guys won were mostly robot part samples I've purchased to evaluate their use for the charity.

(the charity does after school programs, robotics is our bread and butter)

This "Gap" game was an experiment for the charity to promote education to a world wide audience.

Frits and a couple others knew about this and gave their permission before you guys entered this competition.

When the charity does another one of these events, you guys will be able to win expensive prizes.

For example each of the 4 prizes offered in this game would normally cost you a few hundred USD each.


However next time, I'm going to have to do a better job on my side as I left this game too open and created some drama.


Ok guys the tracking numbers will be sent out today to the winners.


Thanks for playing!!!

First of all, I want to thank winfieldrobotics for the great challenge he offered to us.

Secondly I want to congratulate the winers, they had realy neat designs, simple and efficient. Also thanks for your appreciations.

In the next days, I will make a new subject with the robot, with some more pictures and explanations and with my oppinions about what was good and what was not so good in the process of making this robot.


PS: NO furnitures were harmed during making of presentation movies :D


for setting up this challenge, and the generosity shown in providing the prizes.


My congratulations goes to antonio.caciuc > as the winner, for an exceptionally speedy robot.

My congratulations also go to  sebathorus for the latest version which is very controlled and efficient.

Great fun :)

Well, I stayed up very, very late (too late actually) last night trying to finish creating a movie, and getting it uploaded. I had to figure out how to use Windows Live MM, on my new computer that replaces my somewhat dead old one. Then Vimeo does this to me. If Vimeo doesn't get its act together pretty soon here, I shall be uploading this thing to YouTube, much as I really hate it. I may as well post about the robot here right now.

I used my Lego Mindstorms NXT kit and a whole bunch of other pieces, something that could almost be called cheating... :-O. And, it didn't fold back up into a 12x12x12 box after crossing the gap, something which a couple of the other robots did... but aside from that I think I did pretty well. If you guys think that using Lego really almost is cheating, I didn't really enter to win, more just to see if I really could make it :). I'll post link to my video here, that way if it does get converted without me knowing it, you can still watch it.

Thanks for putting this contest together, winfieldrobotics!

-EDIT- Oh and if none of this makes sense it's... the... lack of.... oh look, dancing unicorns!!!

NXTreme I can't watch your video as of 9:41 AM CST, it just says waiting in line.....which is a problem on the website's side.

I'll try again later today.

But I'm cool with Lego robot entries. (I've used them for this game)





Well, lets forget about Vimeo for now, I uploaded it to my Picasa Web albums instead. I might try to add some pictures later on, once I take some :). Sorry for submitting this so late, but that week that the computer quit on me set me back by, uh, a week. Good luck to all!

-EDIT- Just got an email saying that my Vimeo video is now online and ready to be watched! Sorry for the delay.


27 seconds.

That was a BUNCH of Lego's!!!

I had something else to do and missed the exact deadline, but that's ok as it was submitted before the cut-off time.



I hope you don't mind me asking, but from when to when was the 27 seconds counted? The robot didn't actually leave it's box till it beeped, that's when the program started. The delay was probably because I was downloading via Bluetooth. I don't want to argue the score, just curious and wondering.

Yes, it is a bunch of Lego's! I've been collecting Technic sets for quite a while, and quantity of pieces makes up for my quality of construction :).
