4886A World Championship Preview

Enough of this wallbot nonsense. Project GLaDOS may have failed, but our team is still alive. This is our robot that won the gold division at our pre-worlds scrimmage, and will be competing next week (more or less, it has changed a little).

6 motor 1:1.6 high speed tank drive - fast and powerful
2 motor 7:1 torque lift - max capacity 18 sacks
2 motor metal chainsaw intake (inspired by 2915A’s June robot) with piston-operated polycarb offsetting table

-Quickly gathers sacks from anywhere on the field (5-1-5 in one swoop, same with wallsacks)
-Scores all goals
-Descores all goals
-Gathers all sacks from a 14-15 inch wide section of trough into intake in 3-4 seconds
-Does not get stuck on sacks
-Variable autonomous
-Retuned and ready to go on mats treated with anti-static spray

The goal of this robot was to have a design with all the abilities of a “NZ robot” but also have a six motor drive for strength and general reliability and robustness. I think we pulled it off quite nicely.

It looks like a really nice nz bot. Does it have a high goal flipper or with the six-bar can it just reach that height with the intake?

Watch this video. It shows everything.

Its labeled general promo in the reveal.

It has a lever-powered high goal flipper which can put 6 loads nicely on the high goal. It can also descore the high goal. The lift is a four bar.

Please stop spreading the “NZ bot” idea…
For starters, there aren’t really any identical “NZ bots” anywhere. It’s not like they started the 4 bar and top roller (which this is) and everyone started copying.

Also yes, they can score high goal.

Oh gosh… did you have to put that in the video? >< D:

Scores really quick with a solid descore :slight_smile: definitely a robot to look out for at worlds…

I do realize that, but it is just faster to say nz bot to describe a robot. Then to say 4 bar with top roller.

“Approved by Jack Barker himself” #lol.

Are we approved :stuck_out_tongue:

What about dat overloaded static spray :wink:

We have found our robot twin. This is kind of freaky.
Exact same gear ratio on the drive, lift, and intake.
Same motor allocation and same exact intake bars (partially since we were inspired :wink: )
unfortunately I don’t have any pictures to compare with/share. Our chassis is pretty different though, and we used a six bar.

Haha :stuck_out_tongue: sounds like our first one ( the different chassis and the 6 bar. We went this way because we knew if we got it to work it would be good

Yeah, we didn’t want to redesign to the 4 bar because it would have required a full on drive change. It gets a little extra power from pistons to make up for the extra length of the six bar. How well does your chassis do at driving over sack piles or do you not feel like its enough of an issue to worry about?

Our chassis doesn’t get stuck at all on sacks, ah the power of 6 motor drive.

Awesome chain-saw roller robot :D. Will be looking forward to seeing you at Worlds!

Looking good guys! Having competed against this robot many times I have to say that every match against 4886a is tough. See you guys in Anaheim!

Glados was cool; too bad another special robot wasn’t finished I always like to watch the matches those kind of robots compete in at worlds.
Your new robot will definitely do well at worlds. I like all the videos because they really help in explaining the robot’s functionality.
