Looking for Sumo Robot resources/supplies

Hi all,

As a team building exercise my workplace has announced that there will be a Sumo Robot competition. I’m thinking about entering, and I’m looking for a sumo bot, and even a ring to practice in.

Since the competition is in less than a month, I’m looking for a prebuilt platform. Another competitor is buying one of these: Zumo Robot for Arduino [v1.2] : ID 1639 : $109.95 : Adafruit Industries, Unique & fun DIY electronics and kits

So, does anyone:
a) Have a Sumo Robot they aren’t using that is under 14 x 14 cm and 400 grams that they’d like to sell?

b) Has a Sumo Robot competition ring (100 cm) lying around that they’d loan out/like to sell reasonably?

Thanks for reading!

P.S.

Here are the rules for those who are interested:

Here’s the basic rules:

Two robots placed on starting lines in ring. Once activated, they each attempt to push their opponent out of the ring. This continues until the time limit or a robot is pushed out . Match may be restarted by ref in case of stalemates, inactivity, malfunction, or mutual falls,

Ring Description

  • elevated surface.
  • diameter ~100cm.
  • matte black in color.
  • 5cm solid white border.
  • Two parallel starting lines in the center.

Robot Requirements

  • autonomous; no remote controls
  • self-contained power
  • wait 5 seconds after the ‘on’ switch is flipped.
  • fit inside an 14x14cm box
  • no height restriction.
  • not more than 400g in weight
  • no fire, acid, electro-magnetic pulses, or other potential hazards.

Rules

  • Robots weighed and fit in sizing box before entering ring.
  • must begin on the starting lines.
  • at ref signal, contestants simultaneously press start on their robots.
  • After a five-second delay, robots will engage
  • referees can restart match at their discretion: if robots are locked together, neither robot moving, both robots fell out of the ring without a clear winner, gross malfunction, false-starts, or human interference.
  • match ends when one robot has disabled or ejected the other robot, or after the time limit has expired.

I started building a pair of mini-sumo but sort of lost steam halfway through…

I do plan to get back into it and get these finished at some point…

I also made up a mini-sumo competition ring but it is only 77 cm in diameter and is made out of 5/8" MDF painted flat black with a white ring around the edge…

You are welcome to borrow the competition ring if you want…

I have:

@hectorh: wow, that’s cool!

Would you be willing to part with them?

Yes, my world domination through sumo robots plan is on hold at the moment

I was also working with a Parallax Sumobot as a platform for a micromouse. It was one I found in a box at VHS. If you’d like it, let me know and I’ll reassemble it and drop it off. It’s made to be controlled by a Basic Stamp, programmed over Serial, but either of those can be bypassed fairly easily.

@Shane As long as you didn’t sink too muck work into it, that would be
great!

Thanks!

Sure, I’ll be out for a few hours. Do you want it tonight or can I bring it on Monday or Tuesday? Only takes me 30 minutes so just let me know what works best for you.

Whatever works best for you, Shane.

I’m happy to pick it up tonight or Monday.

Sorry, I just got this now, I’ll drop it off tomorrow.

Dropped off for you in the drop box. The two books can go in the cardboard box labeled sumobots if you don’t want them. It’s on the top shelf, opposite the 3D printers.

Thanks @Shane
