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)

If your problem is virus related, have you considered using your Ubuntu partition to run a virus scan on your windows partition?

Unfortunately, it's not virus related. I think the culprit is actually CCleaner. I ran the registry file fixer tool the last time that Windows started correctly, and I think that it messed something up. I did back up the changes made, but I don't think it's possible to undo the changes (with the backup) unless Windows will start up, a bit of a catch twenty-two. I took it to one tech today, nothing he could do. Gonna write another one and see if he could do anything, if not I'll just re-install WinXP and keep going :). Fortunately, it's all backed up...

I'm going for the fastest time. but..I hope my robot will be ready on time.. I'm now working on the L298n motor controllers.

I really want to see a robot that crosses the gap quickly (and doesn't get stuck on the edge like mine did...)

This shouldn't take more than a weekend to build. I would really love to have some competition.

I'm working on my entry right now. However, I'm not sure I'll be done in time. I'll post it as soon as possible, even if it's not in time for the contest.

By the way, when on the 23rd does the contest end? I saw the 19 at the end of the date, would that be 7:00 o'clock PM on the 23rd, or is the 19 irrelevant and the contest really ends at midnight? I might have a slim chance of finishing my bot and uploading a video if it's at midnight. I should know by now not to leave these things to the last minute :). Thanks!

Yes that is 7PM -CST for the US.


The end date/time has no real meaning, its just a random date/time I chose when making the comp.


Well then, I guess I'm sunk :). No way I could finish programming it in time. I will post a video of it anyways; when I'm finished. Thanks again!

Isn't the deadline in April? You still have one month left... that should be more than enough time to complete the programming...

Oh....! I just about killed myself laughing! Thanks for pointing that out! I really must have been thinking too hard... now I will have time to finish it!
