incredible way to hang!
i have never seen a robot that can do this reliably
did you guys have issues with the 1:8 arm being too slow during in-game play?

Thank you! The first time we figured out we could hang like this it was sort of an accident, but worked well so we stuck with it. The 1:8 gear ratio for the four bar arm wasn’t too bad, I never had a problem with it.

i think you guys had a good robot and we considered picking you in Manchester (2625a) but i only saw your robot hang on the practice field there never in a match and the one time your attempted it (in the finals) we had sparticles use there claw to block it but overall you did a good job and added a twist to a common design

You must be thinking of 228B, GUS’ other VEX team. Team 228A, this robot lost in quarters, and successfully hung about 4 times through-out the competition. 228B had a very similar design, but a couple of flaws when it came to hanging, which you guys figured out and blocked them. Congrats on that. You were the only ones to figure it out.

honestly we didnt think of it till they were in position to hang then i yelled at joe on sparticles to hover the claw over the robot and there alliance was no match for our robot so we dominated in the last 30 seconds or so

and your parallel bars weren’t truly parallel were they?

Parallel four bars are for weenies. :p. Both GUS teams figured we’d have better range of motion with un-parallel four bars. Worked for us.

well my weenie team did pretty well with them last year and is planning on using them again this year:p

HEY!!! We are using a double 4 bar

Oops! Hope I didn’t offend. Just both of the GUS VEX teams had originally used parellel four-bars, but we scraped them because with the arm being parellel it wouldn’t flip backwards correctly, so we couldn’t hang. Therefore we just moved the bottom bar up a hole or two, and it worked perfectly. :D.

our robot was suppose to have a parallel 4bar but i think one of the bars were off by a gear teeth so it was weird sometimes
at first we thought we had BENT our tower or something for it to be at that angle…

didnt offend me, we still won that day and u may have just helped me a ton thanks

[murdomeek]

let me give you an advise, make sure your robot doesnt tip

[Paul_T_27]

thanks but we cadded it and according to autodesk its fine and we have our drive set up in a way where if it starts to tip the driving wheels are suspended

how heavy was your robot that the 1:8 ratio was strong enough to lift itself up???

Probably around 10 pounds? We used AL for most of the robot.
