FRC488 - team xbot presents X8: The Ocho

[Vikesrock]

That's a really nice looking robot! If it works half as good as it looks (and the video suggests that it might) 488 will definitely be a strong competitor at any event you attend.

Nice work!

No rush of course, as we are tired of looking at our shops too.

We leave late next week traveling to consecutive East Coast regionals and driving to both of them from Baltimore. We have to drive 3 1/2 hours right after flying for 15 hours (with stopovers) to get to the VCU regional area.
Too bad I'm the lead driver.

If your going to Championships, I will definitely look for your team and stop by your pit.

Good luck this season, even though you folks dont need it.

We'll keep an eye out for you in Atlanta. We're already registered and looking forward to it.

Are you flying into Baltimore-Washington Airport? Richmond shouldn't be more than two hours in good traffic, if I remember correctly. It's been a long time since I've made the drive and it's undoubtedly slower when you've got carloads of people, but it was a pretty easy, if uneventful drive. Of course, I've never done it after a fifteen hour day of flying.

I'll never complain about our three hour ride to Portland again. Thanks for the wishes of luck. We try to minimize its importance, but having it on our side is never a bad thing.

Nice work!

Thanks! We've had a lot of time to run this robot into the ground and iron out any bugs, so it's become quite reliable. We're excited to see how it will stack up against the competition, but we're confident that we're in for a good season.

This robot is probably the most reminiscent to our teams that I've seen yet. Designing the perfect forklift mechanism is hard, but we think we have come pretty close. Awesome robot, hope it does great.

IR-based hybrid controller tells The Ocho which Overpass position contains our trackball; fourth function is "abort".
Matlab-based trajectory generation software takes way point and heading information and generates hybrid movement code automatically.

These are my kind of engineers!

How many travel stages are in your elevator?

Looks great - especially the paneling!
good luck from 973

[flamefixed]

first off, i do hope great minds think alike! haha. heres why -

we are sporting a lift, leaning backwards to keep the mass of the ball central over the bot, cascade style belting, driven up AND down with two cims by an entirely fabricated gearbox and a combination of delrin and 8020 rollers and t slots. (though are entire "guillotine" we call it, is made from 8020 stock.

many similarities. puts my teams mind at ease about our design more


looks incredible. best of luck to you!

What's the overall length of your robot? We apparently made our base too long to implement an arm correctly.

Otherwise, awesome job! Good luck at your competition.

WHAT TIME IS IT?!?!?!?!?

488!!! Many fond memories at Silicon Valley last year, and hopefully we'll see you again in Atlanta!

Beautiful robot. I like the tipping back, which I haven't seen yet this year. I only have one item to point out. How are you on other robots knocking into Ocho, either tipwise or possibly knocking the ball out?

[Vikesrock]

Points from the last two posts appear to be clearly addressed in the robot stats that were posted

GIVE IT UP FOR DELRIN!!! Thats the material we used to build our cams that manipulate our fork while being lifted.

The robot is about 78" long with the forks and inclinator in their lowest position.

A significant percentage of our robot is plastic, with much of that being delrin.

• Our omniwheels are largely delrin, as are all three encoder mounts.
• Bearing blocks in the drivetrain are a mixture of delrin and polyethylene.
• Pulleys on the inclinator are each a combination of delrin, ABS and polycarbonate, while the winch drum is made from polycarbonate, delrin and polyethylene.
• Ball manipulator gussets are all polycarbonate, while it has polycarbonate ball stops and polyethylene skids.
• Electronics are mounted to ABS
• Dewalt XRP pinion is mounted to CIM shaft with delrin
• Spacers everywhere are delrin
• Linear slides on inclinator are polyethylene, rollers are nylon.
• Pneumatics are mounted polycarbonate, tubing take up reel is polycarbonate, ABS and delrin.
• IR board is delrin and acrylic.

...that's off the top of my head. There're probably many other things I'm forgetting. We love plastic.

Very nice robot – a truly elegant job on the paneling, and a design that's clearly very capable at the game. Sounds like a phenomenal sensor package too, I wish we had that kind of intelligence on our robot. My only qualm is at your mention of redundant cabling... because our elevator lacks it. Not that we had room for the extra weight anyway . Good luck and 766 will hope to see you at Championships!

Will that fit inside the 80" cylinder?
