5003 Pre-US Open Reveal

VEX V5 General Discussion VEX Robot Showcase
1

As the US Open is getting close, we figured that we should post a short reveal of our robot. This is version 5.0 of the the robot, although the overall concept has remained relatively the same since early August.

Specifications:
Drive-

  • x6 393 motors set at 100 rpm
  • 4wheel raised drive base with a chain-wrap at 1:2
  • Very fast and can easily maneuver the bump

Lift-

  • x2 393 motors at 100 rpm
  • 6-bar lift geared 7:1
  • Reaches well over 24"

Intake-

  • “Magic Intake” set at 160 rpm
  • Rubber band wrapped sprockets as large ball intake
  • Does not have to pin large balls to intake

Thrower-

  • Throws out the back of the robot
  • x3 D/A cylinders (used as single acting)
  • Three reservoirs allow for 15+ (good) throws throughout a match
  • Can throw over the barrier without raising from the hanging zone
  • Can completely descore large balls from the scoring zone
  • Can hold three buckyballs and still throw large balls

We have had a fairly good season. We ended up winning three local tournaments, including the Indiana State Championship (With 323z and 1115c). Our unofficial robot skills score is 90, but most of us know how that goes! I don’t have much in the way of a formal reveal video, but I think we will have a more in-depth reveal closer to Worlds. I linked a video of the thrower from my phone and I’ll link a video of the buckyball intake as soon as I get it uploaded. If you have any other questions, feel free to ask!

Do you have any stability issues with the catapult made of standoffs?

Also, why the cut up flaps?

After a lot of testing we have not experienced any issues with either the thrower holding up mechanically or with the the large balls not being adequately held within the thrower. The arms are also far enough apart that the large ball will sit down securely within them.

The flaps originally were cut for the last version of the intake so that they would not hit the pieces of c-channel that held the rollers in place. On a whim we tried them reversed on the new intake to see if they had a noticeable effect while taking in large balls. We found that they do not affect the performance of the buckyball intake, but they do allow the large ball to be more easily pulled over the rollers.
