This is a great robot. I guarantee that most of the robots at worlds we be a variant of this. The stacking mechanism is a little weird, but that can be improved in a couple ways. Nice job, I will definitely use this as inspiration.
Theoretically, if they had made the arm higher up and had angled it downward better they could reach the highest due to the hypotenuse (the arm) always being longer than one of the sides (the support pillar). There is no need for an RD4B or any of that sort.
I built a very similar robot after getting inspired by yours but I can't seem to figure out one thing. Whenever the platform that the cubes go on comes out to 90° it can't push the arms out and the tower falls. Any ideas how to fix that?
Make sure nothing is contacting the cubes besides the bottom of the tray when it comes out to 90 degrees, as well as that the tray cant physically go past 90 degrees (you can use a hard stop or something for this). The bottom cube should also ideally be contacting the ground when the tray comes out to support the rest of the stack. Also you might want to try slowing down the speed of the tray when it comes out.
@Midnightplays We were thinking about doing this, but we decided that it wasn't worth it, as we had enough motors anyways, and also because it would add a lot more complication because of the extra chaining/gearing that would be required. Another thing to consider with running one motor on the intake is that the rollers actually require a lot of torque to be able to collect and push up 5+ cubes. We are currently using 200RPM V5 motors on the rollers, and even then we wanted to switch them to 100RPM V5 motors to get more torque although we unfortunately didn't have any. So its possible that 1 V5 motor might not have enough torque to collect multiple cubes, but we haven't tested that yet so I can't say for sure.
@@jonathanhuang7364 the cubes are pretty light. The V5 motors should be able to hold up five to seven cubes with no problem, especially with the 100rpm gearbox. Are you sure the reason hou seem to need so much torque isn't because something is generating a lot of friction?
I’m doing something similar and we have a comp Sunday and we are having problems with flip out I was wondering how high the standoffs are and what size. Thanks if you can help
We designed a one-way gate mechanism at the height of the second cube attached under the tray so the cubes won't slide down, but due to time restrictions, we weren't able to refine that and use it on the robot.
@@r3v3rbrobotics35 The one way gate was actually attached to the chassis, so when the tray was up, it was hidden, and when the tray was down, it stuck up through the tray. Kinda hard to explain.
R3V3RB Robotics it was just a little peg type mechanism that held the stack, so when we put the cube tray forward to score we could simply back up and the one way gate would not get in the way.
Using elastic bands on the back, if u open it up the bands will pull together making it go up, but a good add on to this is to have sliders at the top so it can increase in size after that. U can easily get 9 plus stack. In one of my resent compations a team called 7K got a 9 stack in auto using a mix of these strategies
Tbh, this could be a worlds quality robot with a few minor improvements such as the intake. A good intake will be the difference between a mediocre and a great team this year.
A good intake is almost always the difference between a mediocre and great team, in my experience. Obviously the performance of the rest of the robot matters, but time after time the teams that pick up the objects the easiest, through a combination of good design and good driving, do the best.
@Piyush Awasthi The robot has to start the match inside 18"x18"x18", so the rollers and tray extension fold inside these dimensions and then flip out at the start of the match. You can see this working at 0:25.
@@kevinzhang290 aiii litt. I'm an FRC team member and I'm gonna be mentoring our first ever EDR team. Did you guys have to like order any special parts for this bot? My eyes are on those rollers on ur intake they look sick.
Alec they qualified for worlds and were supposed to be the state champions but they got DQ’ed. For pinning they didn’t do, they argued with the refs and they got dq’ed from all future comps for something really stupid. so they couldn’t go to worlds.
The rollers are tucked behind standoffs at the beginning of the match so when the arms move up, the rollers move past the standoffs and the rubber bands then pull the rollers out.
Nice looking robot, but it doesn’t look capable of reaching the height tower, and the stacks don’t look very stable either. But other than that it’s a pretty good mechanism.
This might be the legit highest quality ri3d I've ever seen
Adam Fu thanks man
Shoulda seen the NorCal version lol
Rewatching this makes me emotional

most of every robot that will go to worlds would be base on this design or something else but this will be a great bot
LMAOO worlds
you were indeed right, if worlds happened
This video only just starts to uncover how much of a high risk game this is for BO1
horrible game
@@Tonydudeo imo I love it. it's a great game, just not exactly suitable for the new format
@@stevenbarksalot on to bigger and better things
First vex reveal I ever saw :)
Amazing design definitely popped a few ideas into our heads
how does it feel making the meta
It feels good
shashank ojha they created the meta... and anyway it’s the only type of bot that works 😂
throwback to a robot that inspired the meta. ggs.
Looks good. Interesting way to open up from starting position
Wow, if the outake would be smoother this could be the meta
This aged well
#priusgang reilly at our competition this was the meta
Literally every single robot now is a tray stacker imao
IT IS THE META BUDDY
Glad to see Recycle Rush Jr. has good Ri3Ds!
trash vex game
Recycle Rush Jr with the Cartoon powerup cubes from the scale :)
yo at a tournament, they accidentally played this video on the projector
Honestly, very nice.
Is there a video on where I can do this exact design? For tower takeover
There is a documentary for this Ri3D which is linked in the video description.
great reveal! was thinking a similar idea except be able to reach the highest tower via a 6-8 bar
Elrond TD why 8 bar? Typically really flimsy and hard to control. I would definitely stay away from those.
ZackJo_11495A prob 6 bar, honestly i don’t know. you honestly could go dr4b but i have no experience with those so...
try a danny lift
Theoretically, if they had made the arm higher up and had angled it downward better they could reach the highest due to the hypotenuse (the arm) always being longer than one of the sides (the support pillar). There is no need for an RD4B or any of that sort.
10 bar here i come
Recycle rush???
Can you put a tutorial on how to build this bot or an instruction manual?
GamerWarrior FL not how that works. :/
actually a documentary will be coming out soon.
This battlefield and room look like my school. Did you do this in the Science Academy?
Yup, the reveal was filmed at the Science Academy. It's an incredible facility!
Yep. I also go there and one of the people on the team mentors me :)
lol joseph you didnt know they shot at the lab
My team was a first year team and we only had a basic claw bot
Let's get this to 100k!
200
how are the 2 sides of conveyor belts tensioned to be pulled together ?
This will be explained in the documentary coming out soon, but both of the rollers lock when they flip out, making it so they can't move.
very solid design

made the meta, they did
Hi, just wondering, did you guys use any locking mechanism to keep the intake rollers in place after flipping out?
Yes, this can be seen in the documentary in the description of this video.
could you change the robot so you only need to have one motor on the intake?

@@jonathanhuang7364 I think you should put something under the rollers to keep the axles straight. The chain is likely bending the axles.

I'm assuming you're talking about the standoffs that hold the rollers in, in which case they're 6".
Nvm I came up with a new design
wait so how do you fit that top part into the robot area? Does it fold inside?
Yes. It is legal to make it so it can flip out of the area.
My team just made it to the quarterfinals :(
PatrickThings my team made it to state
Damn bro you didn’t have to do him that hard
My team made it to worlds
Damn bro
you didn’t have to do him that hard
Cool idea
How much is your robot?????? I want to buy it. Thank you!!!!!!!!!!!!!!!!
5k to adopt
Lmao
Was there no height restriction? Back in 2015 my team made a 3 tier sliding lift in order to lift blocks while still being in the height requirements.
This year, there is no hight requirement, but the side extension rule still applies
There is still height limit, but only a starting height. We made the robot flipout, and this can be seen in the video.
next year can you also do a video like this with the new set up. Earlier in the year please. Thanks! You guys are awesome!!!
I subscribed
That is beautiful ❤️
Aye quick question, what happens to a stack on ur bot when ur tryna score in one of the buckets
We designed a one-way gate mechanism at the height of the second cube attached under the tray so the cubes won't slide down, but due to time restrictions, we weren't able to refine that and use it on the robot.
How does it release when you are placing the stack?
@@r3v3rbrobotics35 The one way gate was actually attached to the chassis, so when the tray was up, it was hidden, and when the tray was down, it stuck up through the tray. Kinda hard to explain.

Kevin Zhang can your bot grab the lowest cube in the stack and place it in a bucket, or do u have to get the cube off the ground
Nice design !!
How does that ramp flip open

how do you flip the top part
Rubber bands tension the top tray portion so when the arm moves up it pushes the tray up with it, and the rubber bands do the rest of the work.
your on to something!
Wow, good job. That is a very effective design. How reliable is the stacking of the cubes into the scoring zone without the stack tipping over?
carol 123 long as u aren’t bad it’ll work
@@Tonydudeo in other words... git gud
Isn't there a starting height the robot must be confined too?

@@piyushawasthi8185 No we just used stock vex sprockets, chain, and flaps for the rollers.
Really good but, isn't this over the height limit?
There is no expansion limit this year.
Unionjackjz you still hafta fit he 18x18x18🤡🤡
Isn’t there an 18” height limit?
The dimension limit is 18x18x18 but once the match starts you can expand beyond the size restrictions. Their robot expands after the match starts
What do y’all use for the fold out. Rubber bands? I can’t figure it out.
E Justus are you talking about the pivot point or something else
U use rubber bands with stand offs to open it
Nice vid. Just subbed 😉
How did you do in turning point
Alec they qualified for worlds and were supposed to be the state champions but they got DQ’ed. For pinning they didn’t do, they argued with the refs and they got dq’ed from all future comps for something really stupid. so they couldn’t go to worlds.
@@8pxl_ That's very debatable
think thats how the story goes.
what releases the tension on the rubber bands to fold it out?
