Is that a 3d printed PVC pipe hex plug? Could I get the model for that?

Akash, you forgot the box!

Looking good! Good luck this year. Only question: Are you worried about being too top heavy when moving throughout the playing the field and suddenly stopping? Just wondering.

Seem some 2009*shudder* inspiration in this robot.

Re: pic: Titanium Tomahawks 2170 Teaser
I'd work on some weight down low if you can. If you accelerate quickly and then stop suddenly this robot is on its side.

Personally, I'm curious about how that ramp is getting raised and lowered. I'm liking the concept though--this is borderline cheesecake-able to help a team operate at a higher level. |
Re: pic: Titanium Tomahawks 2170 Teaser
This is very similiar to our design. We are using pnuematics to raise our floor(very slowly) and close off the opening for the space that we intake fuel from the floor.

That ramp (elevator carriage) is supported on each corner by a 3D printed bracket bolted to a linear bearing. The bearings are each riding on a stainless steel rod, one in each corner. The current plan is to have a run of #25 chain on either short side of the robot (two total) and bolt the chain to the carriage. Idler sprockets at the top of the robot will be connected by a shaft and we'll tuck a gearbox in the drivebase to power it on one side. |

What're the black rollers made out of? It looks like continuous strand carbon fiber.

Re: pic: Titanium Tomahawks 2170 Teaser
Does your "elevator ramp" drop down to "ground level"? How are you lifting ground fuel up to the "ramp"

The cut-out piece of ramp will be re-attached with a hinge to act as a "trap-door" that folds out of the way when the elevator is in the floor position, and folds back down when the elevator lifts the ramp to score in the low goal (between the two black rollers) or dump into other robots (above the top black roller). |

Sick bot guys! Can't wait to see it in action.

Re: pic: Titanium Tomahawks 2170 Teaser
And Akash I really want to see those cinematic shots of the robot before the reveal haha
Good luck this year to your team. Quote:

Thanks Derek - please follow the Facebook and Twitter for all media! I'll have my DSLR in the shop near the end, we still have a lot of work to do. Your sheet is looking sick so far! Some background on this team: very intelligent and enthusiastic kids and mentors, very little school support. This robot is built with COTS parts and only manual hand and power tools. 3D printing helped a ton filling in the gaps! We also only meet three days a week, of which we lost 3 to snow days, so things have e been tough. I'll make sure the kids update social media often. :) Thanks for the support! |

Without giving everything away, this robot's fuel manipulation prioritizes volume over scoring directly. At lower levels of play, this robot can cycle gears and hang, with some low goal action whenever the robot gets the chance to score a point or two. At higher levels, this robot could grow into a great assisting robot, helping top tier shooters with fuel acquisition. Quote:
The floor raises and lowers primarily because it nearly doubles the robot's ball capacity over a more conventional belt-driven ball loader thing. The floor also needs to be at a few different heights for the various outtake functions the robot can do. Quote:

Contrast it to the message posted directly above you, which is saying exactly the same thing but in a much nicer tone. By phrasing the concern as a question, it invites the team to respond with their plans to lower the CG of the robot. If the team truly didn't plan for this, they get the information needed to know it's an issue, and if the team did plan for this, they're able to respond with their plans for doing so. |
Re: pic: Titanium Tomahawks 2170 Teaser
Awesome looking robot, best of luck to your team!

Good luck interested to see how it works out |

As for feeding other bots, we're really hoping we get to a-bomb into a few bits! We purposely built a waterfall intake so we could also hold balls in the conveyor Incase we want to just reverse it to feed others. |
