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.

The music takes me back 50 years!

If the bot encourages youngsters to have a go, that's reward enough :)

Very nice, Kelpy!

Thank you, MarkusB


Well, I wouldn't go quite that far, IG, but thanks anyway.

Another incredibly well built robot from Kelpy. I like the concept.

Now, can we get an "official" timing from winfieldrobotics?

Flattery will get you everywhere, antonio.caciuc.

(I reckon it's about 50 seconds, but I'm not judging) ;)

Very nice !!! Bravo!

Thanks, sebathorus :)

Hello Kelpy,

I've had to ask a relative on timing your video, as from the camera zoom, I can't clearly see when the start side bridge lifts off the table. We had to use the glare in the window, and the angle of the bridge to judge this.

We both agreed within 1 second of both the start time and end time.

(drum roll)

We put the start time at 1.31 (first power switch on) and the end time at 2.23 (bridge angle).

52 second runtime (based on the limitations from the video)


I like the foam board construction!!!

"Heath Robinson" -LOL
