I have been documenting my (erratic) progress on my mini-sumo project, Seeker 2x, on my Trossen blog, but I suspect a lot of people don't read them, so I thought I would open a project thread for it here.

Seeker 2x (http://www.huv.com/miniSumo/seeker2x/) is the successor to Seeker 2 (http://www.huv.com/miniSumo/seeker2), my "champion" mini-sumo. Seeker 2 has been in operation for about five years, and I've wanted to build a new one for a couple years. The design goals are faster, lower, smarter, more aggressive.

The project is well on its way now. I have a hard deadline of mid-November, which is when the next Canadian National Robot Games are being held.

It's a really nice project!

Seeker 2 the project that pulled me into trying to build a mini sumo! :veryhappy:

I can't wait to see what you will come up with. I want to participate to the CNRG too, but I'm not sure my bot will be done in time.

So, I finally broke down and decided (with 3 weeks to go before the 2009 robot games in Toronto) that I'm going to finish this robot, dammit!

Awesome, can't wait to see it. I know the feeling too. Gotta get Issy finished for fire fighting.

I know the feeling, I'm rushing to get mine done in time! Electronic board should come in this Thursday and I should finish the body with extra weight by the end of the weekend... I... must... finish... on.. time. Got most of the



Awesome, can't wait to see it.

Not me! I'm possibly going up against it :(

Awesome - make sure you guys come and introduce yourselves to me. I'll be at the registration desk before things start, and after than I'll be hopefully running Seeker 2x...

Yep, robot or no robot, I'm going to the CNRG. I have my train tickets (only 4-5 hours from Montreal, compared to like 8 hours in car and 10 by bus) and I'm looking into motels for the weekend.

I'll make sure to say hello!

Since we had this big CNRG discussion, just a reminder to anybody not on the CNRG forum (seth, I'm looking at you):


The Canadian National Robot Games are coming soon November 21, 22 at the Ontario Science Center. Pre -registration closes midnight November 12th so if you want to guarantee yourself a T-Shirt and Competitor bag please register as soon as you can

Jon, the work here is simply gorgeous. I would love to see more about the process behind making the wheels.

Jon, the work here is simply gorgeous. I would love to see more about the process behind making the wheels.

Here's my machining instructions for each wheel:


start with 1" diameter rod
turn to 0.905" outside diameter
face it both ends to 0.984" long
cut indents in outside face
center drill main hole from outside (go in 1/2") - drill to 3mm
turn around wheel so outside face is against chuck
center drill 0.600" in, use 1/4" bit
center bore in 0.667", to 0.787" inside diameter
smooth inside face
mount wheel in milling vise, with ends of wheel against vise plates
drill #4-40 tap hole through both sides, dead center (center of hole is 0.177" from front edge of wheel)
mount wheel in milling vise, outside face up
align set-screw holes with vise (use threaded rod and machinist square)
align center of wheel to spindle
run CNC program to drill 6 pattern holes
holes are 13/64"
countersink each hole slightly by hand

Awesome! How was the tread molding done?

You can see in this picture:

http://www.huv.com/miniSumo/seeker2x/Seeker2x-TireInMold-01.jpg

the wheel in the mold, with the polyurethane poured into the gap (I use a large syringe for that). The mold is a two-piece mold, and it comes apart once the polyurethane has set (16-24 hours).

Update - new picture... Almost done - all that is left is molding the right tire, doing the front scoop, and painting it. After that its all software...

Monster Mini Sumo Bot! That looks awesome Jon great work, All your bots/work I've seen have such great quality and craftsmanship.

Looks like the "Top" is from a 3d Printer? Am I right?

JonHylands

Yeah, I printed the lid (and a couple supporting pieces) on my Dimension uPrint. Its much simpler to print small intricate parts instead of having to machine them.

I totally agree, I can't wait to get one... I'm really looking forward to getting one sometime next year, Though I'll be getting a makerbot or one of its DIY Clones. Rapid prototyping opens up soooooooo many possibilities.

Okay, so Seeker 2x is mechanically complete now. I still have to paint it, and write a pile of code, but its done and moving.

Here's the first video:

This thing is insanely fast. Its going to be a real challenge just keeping it under control...

Printing parts? That's sick.

You have some cool toys.

Exactly, sthmck. I've had that very same reaction way too many times to a "first run". I think we can all relate.

So I've been experimenting with it - by turning the speed down to 25%, I can get it to reliably stop without going off the edge of the ring.

Of course, when it sees an opponent with the front sensors, its going to rapidly accelerate to full speed to try and push the opponent off...

I listened to it 5 times and I still find it funny! Adrenalynn, you are totally right about the relate to it thing.

Looks really nice Jon... and fast!
