New Micromouse Fourm?

So is this lovely creature still around? Parts perhaps?

I wouldn’t mind finding one!

So were there any small roller balls on the underside? or was this thing left to scrape on the leading and trailing edge when moving around? :laughing: I’m just currious.

Although this was a great looking bot, I think I like James’s design more.

The little guy is gone. I no longer have the parts to make them. There were nylon screws used as “rollers” on the underside. Was fine for tabletop use.

YES! I believe that brings my total followers up to roughly… 1. :stuck_out_tongue: :smiley:

Do you recall any details, motor, wheels, processor board?

We can rebuild it! We have the technology!

This “Sumo” 'bot is a little closer to what I’m interested in (just received):

For a micromouse, I’d suggest a new bracket to hold a pair of R/C servos back-to-back, and then four spacers to hold a BB2 board above. It’ll need a 3rd “caster” wheel also.

That one looks good. I like the compact look of all the components and the slick wiring. Bots with parts and wires hanging off everywhere is not as hansome looking. :laughing:

The old micromouse kit used servos for motion, but the wheels are very small, 1.5" so instead of doing maybe 9.4" per second it was like 4.7" per second. The processor was a BS1. Yes 8 I/O pins and a 4mhz processor capable of running a program with up to 80 of your favorite basic instructions. Yes, you read that right, the program space is limited to around 80 basic instructions.

The robot you have pictured above is basically the one in this thread. No special brackets required. Although I am ordering up some channels made from .06" material that fills in from ASB503 to ASB506. Adding ASB504, and ASB505. These brackets will allow the center channel to hold an ASB-06 in the front for options, and it will allow the caster wheel to be moved back so the bot isn’t so top heavy.

True, after I dug up and posted the url for the Mark III, I realized it was probably the same pix I had posted on the other thread. The mind is the first thing to go…

Yeah, that’s (yellow) a pretty old 'bot. Other then “Nice to have on the shelf”, I would probably have more fun with a newer-designed (more power!) 'bot.

Are we talking about the same pix?

You’re talking about fish’s SES 'bot. I’m talking about building something like the Mark III. He’s got it built with SES. I was suggesting that a custom bracket could make the mounting of a pair of servos a little more compact (like the Mark III) for Micromouse. but for a line follower, I’m sure it’s just fine!

Yes I was referring to the SES servo bot. My point was it’s already a pretty good little platform even without making a special bracket. But Hey, who knows maybe I should make a custom chassis for it. I will think about it.

As for the term micromouse. 12 or so years ago micromouse meant a really small rover. But nowadays it means an incredibly fast line or maze follower, that can map and find the fastest solution. So I’m purposely not calling the SES servo rover a micromouse.

Yes, the Micromouse that is competitive today is a very specialized (and expensive) platform! I don’t care to spend $120+ on each motor!

My thought was just to get the size down a little. The mazes aren’t that big. I was first building a small 'bot for Table Top competitions (HBRobotics), but just as I got a chassis designed with a pair of LM motors with encoders (tail to tail) the club decided to build up a full size maze (just finished), and start up some “challenges”. Well, my “Micro Moose” was too big for the maze. Back to the CAD package. Now the two motors sit side-by-side, and run through gears.

The Mark III I posted I envision as a low cost way to get a 'bot into the maze for newer robot builders, and kids.

The SES Servo rover was not introduced as a Micromouse, my only thought was that if it could also “run” in the Micromouse maze, it would have an even wider audience. Just a thought!

With two opposing servo shafts, such a bracket might also do duty in the arm department. Just thinking…

If I make up a bracket, I’ll try to keep in mind some additional “servo horn” hole patterns for attachment. Nothing planned as yet.
