Can the Everybot get Cargo from the loading station (human player)?
Not directly. The human player can enter cargo from the loading station to the floor, where it will roll closer to a scoring location for Everybot to pick up and score.
Can you elaborate on why you think defense will be more important than climbing (for an everybot)?
Is anyone built or building or even just used the design but switched some things
Good question! Everybotâs mission statement specifies that the robot should be a valuable asset on an alliance in a regional finals or championship elimination match. As such, we think a team who builds an Everybot should be less concerned with qualification rankings than their ability to contribute to an alliance in the playoffs.
Climbing to level 2 of the Hab, worth 3 points more than level 1, is about equal to a single âcycleâ differential, i.e. a hatch (2pt) or a cargo (3pt). A robot playing defense should be able to slow down scoring robots on the other alliance enough to deny at least a single cycle throughout the duration of teleop. Additionally, the driver practice gained by prioritizing defense will make a team who builds Everybot better at scoring hatches and cargo than if they had put resources (practice/build time, robot weight, money) into a mechanism to climb the Hab beyond level 1.

A defender could stop their opponents from scoring more than 3 points. Say the defender blocks one whole cargo and hatch cycle- thatâs 5 points, meaning the climb has already been made up for with profit. Plus, a low level team probably wouldnât have the resources to build an effective climbing mechanism. If they really need the extra 3 points, they can always send it to get up there, although 118 hasnât had much success with that.
Has anyone had any issues with the âRed Stripeâ motor interfering with ball transfer? Weâre looking at modding the motorâs location to keep it out the way of the ball. If it works, Weâll put up some pics. Iâm thinking this our new rookie teamâs measuring/mounting problem. Weâve had to learn how to use tape measures, how to read them plus use a set of calipers. Mentoring works. Theyâre way ahead of our veteran team. This isnât taught in schools. Shop and life skills are not taught at all.
Theyâve done a great job up to now. This is just a mere tweakâŚTHANKS 118 AND ETHAN!

Key factors in a successful âsendâ are a high CG that keeps momentum and helps lever up the back end, and a tight wheel spacing that keeps the bot âflowingâ on to the ledge. Everybot as designed has neither of those factors in its favor, leading to the performance shown. Teams should think about those factors before attempting multiple practice sends.
We are building what amounts to a modified version using a WCD with 6 pneumatic wheels in a slightly longer chassis configuration.
Itâs a nifty design and hats off to 118 for sharing, but for us the reasons why are as follows:
-
Manpower: Through a turn of events too long to go into here, we ended up with half our students on the business team, an unusually large number of coders, and a mere 3 members working on build, 1 of which is our CAD guy.
-
Simplicity: After saying we should keep things simple this year and build more within our means, nearly all of my mentors and most of the studentsânone of which are directly involved in the design or build of the robotâdeveloped some type of madness after kickoff that left them muttering incessantly about hab level 3.
-
Coachâs Edict 1ââNo Elevatorsâ: Too soon for me after last year. Also, see the part about Manpower.
-
Coachâs Edict 2ââJust use the Everybot as a starting point and then worry about climbingâ: I decided to not have a repeat of 2018 when I burnt the balance of my vacation days trying to scrape together something we could field for competition, while resisting the urge to go âblack glovesâ on the build as our team unraveled due to a perfect storm of scheduling conflicts.
I dunno. I hope I chose somewhat wisely and it works out. In light of all the snow days weâve had it seems like it may have been the right choice so far.

We have also choice to go this route as well
Glad to hear things are going well! We tried to place the intake motor as far out of the way as possible. While it seems a ball could possibly hit the motor as it passes up the conveyor, we havenât had it cause any meaningful interference in the practice and testing weâve done.
The capture area for cargo is relatively small, meaning the ball is pretty much already centered left/right by the time itâs through the bumper cutout.
@Ethan_Reed what is the height from the bottom of that hatch top cross bar to the top of the robots chassis
The distance from the bottom of the Hatch Top Cross bar to the Top of the Robotâs chassis is 17.64 inches. This distance does not need to be super precise as that bar just helps keep the hatch stable when it is in the robot.
@rstockton429 The pvc sits on the top of the top hatch cross bar so it would need reach the hab. Does 17.63inches reach?
How high is the pvc off the ground im having a hard time figuring out a good hight as the cargo ship opening is 2feet 7 inchs from the ground up
The PVC pipes lean against the top of the Hatch Top Cross Bar. The PVC extends about 3 1/2" past where it contacts the Hatch Top Cross Bar. As you stated the cargo ship opening is higher than this. However, Everybot was intentionally designed to use the edge of the Cargoship to help roll the ball into it. Please watch this part of the Everybot reveal video to see this in action.
alright thanks
We just ârookie moddedâ the motor on top of the crossmember and did a vertical connection. Note the multiple âvent holesâ. 7535 is definitely persistent! Their idea was simple and worked!
Looking good! Thanks for sharing your modifications. Please feel free to post more updates; Iâm sure other teams building a version of Everybot would love to see how you improved the design.
Excited to see yâall play.
No worriesâŚthe young ladies figured it all out. We just mentored. Will do
