145 + Glue =awesome?

Our frame now is tougher then Chuck Norris. All thanks to Mr. Epoxy who is married to Mrs. Rivets.











I would like to thank Mr. Wolf and Norwich Glass for doing this for us. Oh and the mentor who to the pics, I'm not sure who it is =P.

Looks great ... but it looks awfully low. Do you have enough clearence for the center structure supports?

[DarkFlame145]

we sure hope so, i have seen bots a lot lower then that.

Way to not do it yourself... you better hope you dont have to change anything... and thats not really going to make your robot any stronger,it will still flex as much as if it was bolted together, you just wont be able to take it apart now... have fun!

Mr. Wolf is a mentor and Norwich Glass is a sponsor of our team. That is the only thing that was not done out of our shop. Some teams have everything fabbed at a shop then all the team does is put it together.

The weak spots on a frame are it's corners, make them stronger then the frame as a whole will be.

The drive train has been tested, our lift fits on it great, and everything is just right. So there shouldn't be a need to take it a part.

I must be missing something here. Why are you using black goo to join your frame members as opposed to something such as say, bolts? What is that stuff anyhow?

[GrammarNazi]

Well those teams suck and they should be kicked out, not that they could enforce that... and the corners are not the weakest spot they have 2 to 3 layers of metal unlike the sides which are long and only 1 layer, unless you varied from the default layout a lot.... i sure hope your right when you say it fits cause it would really suck if you had to take it apart...

It's epoxy, we are saving a good amount of weight, by not using as many.

Bolts can losen during a match and need to be tightened. That makes the frame corners weaker. Epoxy can't losen, so it will make the frame strong all the time. Welding will do the same thing, but welding can make the frame warp. This is just as light weight as welding, but with no warping.

if you tighten bolts theyll be fine, depending on how much stress you put on the frame epoxy will crack, it usually shatters like glass only with a lot of stress though, im sure the epoxy will work fine it will just suck ifi you make any mistakes

Welcome to ChiefDelphi. Helpful or inquisitive posts are encouraged here, but whining, complaining or making derogatory remarks about other people or teams is not.

Keep that in mind as you explore the wealth of information that's available here. Not only do other students see what you write, but mentors, sponsors and FIRST personnel as well. Do unto others and all that.

i only make remarks at the teams that have there robot fabricated by someone else(that to me is cheating and defeats the whole purpose of this team activity) , i was trying to figure out why this team would use epoxy when bolts are readily available, then when the team said why i explained the epoxy does break and that properly tightened bolts should not come lose. i'm not being mean, i'm being curious and realistic

Congratulations on finding a successful fusion of students and engineers that works for your team. It sounds like your team understands the purpose of FIRST far better than teams whose students never touch the robot, or than teams who try to attack this problem with no engineer support at all. Best of luck with the rest of your season.

I'm curious as to why you don't get your frame welded, it's stronger then epoxy and bolts togther, you dont have any bolts to lose, and you wouldn't believe how much weight you'd save not using bolts. Becides if you're sure enough of your frame design to epoxy it togther you'd be sure enough to weld it, because grinding off the weldded joints would probabally be a compareable ammount of work to that of removing all that epoxy.

Surprisingly, welding may not be that much stronger than epoxy (if stronger at all). Welding ruins the heat-treatment on the aluminum, which makes its strength take a nosedive. On the other hand, some epoxies are insanely strong and do not affect the heat treatment.
