Seeker 2x

[JonHylands]

So, I decided to open a new thread for my new mini-sumo, Seeker 2x.

I've set up a page describing the project:

You talk about speed on your page. Dont you want to go for more brute strength? and at under 500 grams isnt seeker //x going to get pushed around even with his speed? If theres not a enough meat on his bones, his tires are just going to spin against a heavier bot even if that bot is weaker, the mass difference will account for that yes?

Dont you want more mass and more torque for Sumo?

I don't understand your front end design, is it meant to lift up an opponent with the upward torque from your motors combined with your opponent's forward force? or is it simply meant to shield your sensors?

As far as I know, typically mini sumo bots must weigh 500g or less.

I've been wanting to make a Stampy 2, and I have a lot of new ideas for it . . . but must finish my other bots first . . .

How will your Seeker 2x be different from the last?

[JonHylands]

Mini sumo is limited in both size and weight - the robot must fit within a 10cm x 10cm (unlimited height) box, in its upright position, and the robot must weigh less than or equal to 500 grams.

Its a pretty big challenge to build an aggressive robot that fits those specifications. Long experience has shown, all other things being equal, the combination of lots of traction and high speed wins.

The front design is intended to pick up the front end of the other robot slightly, which puts the robot in the ideal position for pushing. The front end should never come off the ground - a significant chunk of the weight is on the front end. However, one of the important design parameters for both Seeker 2 and Seeker 2x is that if the front end does come off the ground, the back wheels stay firmly planted on the ring, still able to push.

Admin,

Seeker 2x is 33% lower (1" versus 1.5"), it has much more powerful motors which also go faster, it will use Lithium Polymer battery technology, it has two more sensors (on the sides), and (most importantly) it has a much larger microcontroller onboard.

The PIC 16F876, which I used in Seeker 2, has 8 KB of program FLASH, and 368 bytes of RAM, and runs at 5 MIPS.

The ATmega128 which I will be using for Seeker 2x has 128 KB of program FLASH, 4096 bytes of RAM, and runs at 16 MIPS.

Plus, with its CNC machined pieces and shiny aluminum wheels, Seeker 2x is just going to plain look cooler

Well chyea! Cant pick up robot chicks on just skillz alone!

But yeah I didnt know the weight limit was 500 grams, I thought you were just trying to be super awesomer by putting all that stuff in such a small lightweight package my bad

[frank26080115]

but why the black part over the flat part?
look at my attached pic, is that what you want it to do?

[JonHylands]

Yes, that would be perfect if it did that. Seeker 2x, like Seeker 2, can rock back a long ways (more than 45 degrees) while still maintaining full pushing power.

In reality, most of the time, both robots stay flat, and it just pushes the other one out.

Got a bunch more done on Seeker 2x - you can see my website at http://www.huv.com/miniSumo/seeker2x

looks very promising! I'd love to get myself a cnc mill someday
I can't wait to see a movie of it tearing up the ring
