i am rebuilding my robot and i need help i have a few things already built and i was woundering if it would be helpfull to reincarnate them or build completly new things 4 steel c-channel for a 4 bar if need be [image] the bases for all my prior arms [image] old top of dr6b [image] the 6 b…

does anyone think i need to stack lifts like put a 4 bar under a 6bar or something

Maybe but if you put a 4bar and a 6bar together you may be tippy

yeah i had that problem with a dr6b but that was my first edr build ever i tried some other insane stuff and i couldn’t get it to work but i have seen 1 or 2 good non tippy dr6bs but im better at building now i think…i hope

my coach has just weighed in aparently i am doing a 4bar-6bar i would probably combine the first three images right? and where would i start a 4-6bar in the middle or the front?

Honestly just build a complex tray bot. With your experience you should be able to make a good one (and there’s a reason they’re the most prevalent design). With what you have at the moment, I wouldn’t suggest building a 4-6 bar. You’ll be very prone to tipping with your small base and it will get …

If you’re sticking with a DR4B/6B, you could try using 333A’s build method. [image] DR4B Tutorial by 333A Technical Discussion It is that time of the season when beginner teams are searching for resources to assist them with building their first DR4B lift, and senior teams…

thx @2775Josh but i would have to respectfully disagree complex trays cant do the high tower or intake vertical stacks and in my area at my first comp i went undefeated in quals with a 6 bar that could only pick up one cube because it can stack on top of an existing tray and scene all the good bots…

Well, if you are dead set on building a lift, then be sure to follow 333A’s tutorial, and maybe take inspiration from 21000C. As for your base, you will definitely need to add some wheelie bars to prevent your robot from tipping (or rebuild the base altogether). Good luck with your build!

i will the base is built on 20`s schouldnt that be enougf

also if i do any variation of a dr4b can i power it from the bottom or is it beter to do it from the middle

Doing rebuild need help!
