Near Chaos Robotics

Re: Near Chaos Robotics

Looks amazingly well engineered.

What is the top armour made of, and how did you colour it?

Need to see some videos of the weapons in action, can't make out how they work.

Re: Near Chaos Robotics

Think it might resemble Sewer Snake's?

Either way, it looks brilliant! Looking forward to some video. Seems to have gone together very quickly.

Re: Near Chaos Robotics

The top armor is 1/8 6061, and the paint job was just spray paint and masking tape.

The flipper attachment works the same way sewer snakes does, at least in theory. I should be able to get video in the next few days.

Re: Near Chaos Robotics

Nicely done, look forward to the video.

Very nice good luck at Motorama:

Re: Near Chaos Robotics

Thanks. Also, I put together a fairly detailed build instructable at http://www.instructables.com/id/30lb-Fighting-Robot/

With enough time/money you could build an exact replica of Nyx from that report. I've got .dxf's of all of the custom machined parts linked in the report.

Re: Near Chaos Robotics

Thanks for sharing - thats a great write up, the robot looks really good

Re: Near Chaos Robotics

very informative guide, and nice looking fleet of robots!
Keep up the good work

Motor City Massacre: 1-2, still working but probably getting a complete redesign/rebuild. My girlfriend wants something more destructive.

Kobalos: 6-2, placed second. Looking pretty rough but still running. I'm thinking it's new bot time.

Moros: 0-2, two self induced knockouts. Was still working, then I did a demo with a printer and managed to eject my motor controllers. I also managed to knock the magnets loose in my magmotor and bend a few frame rails. Oops.

Nyx: 2-2, performed pretty well. One loss was due to the drive motor wires unsoldering themselves, the other was my opponent balancing me on the wall. Overall, it did great and will be getting a few upgrades before Dragon*Con

Apollyon: 4-0, 12lb champion. It worked perfectly all weekend.

Also snagged the Best Driver award.

Re: Near Chaos Robotics

Nicely done, congratulations on the award, looks like it was worthy.
Very impressed you managed to run so many robots at one event!
I get my hands tied with one!

Re: Near Chaos Robotics

Finally got around to adding a torque limiter to the weapon system, seems to do the trick-

Re: Near Chaos Robotics

Impressive. Using a torque limiter is a neat alternative to worrying about limit switches.
I wonder if the clutch build into the Dewalt gearboxes would be up to much? What are you using?

[MikeNCR]

Re: Near Chaos Robotics

The dewalt clutch might have worked, but the motor mounts I'm using (team delta) eliminate the clutch from the design and I would have to do a major rework to get that functional again.

I'm using a Dalton OSD225 torque limiter with a 22 tooth #35 sprocket- http://daltongear.thomasnet.com/item/-o ... ce/pn-2032?

It's also on McMaster-Carr as #'s 6524K11 and 6525K11
