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.

@elenateneva7171 4 года назад

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?

@jonathanhuang7364 4 года назад

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.

@VikramKrishna4444 4 года назад

Hi, just wondering, did you guys use any locking mechanism to keep the intake rollers in place after flipping out?

@unionjackjz 4 года назад

Yes, this can be seen in the documentary in the description of this video.

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

@jonathanhuang7364 4 года назад

I'm assuming you're talking about the standoffs that hold the rollers in, in which case they're 6".

@thamos7315 5 лет назад

@zackjo6718 5 лет назад

Elrond TD why 8 bar? Typically really flimsy and hard to control. I would definitely stay away from those.

@thamos7315 5 лет назад

ZackJo_11495A prob 6 bar, honestly i don’t know. you honestly could go dr4b but i have no experience with those so...

@Tonydudeo 5 лет назад

try a danny lift

@hyp3rfy301 4 года назад

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.

@duck8363 5 лет назад

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.

@benji_miller 5 лет назад

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.

@r3v3rbrobotics35 5 лет назад

Aye quick question, what happens to a stack on ur bot when ur tryna score in one of the buckets

@kevinzhang290 5 лет назад

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 5 лет назад

How does it release when you are placing the stack?

@kevinzhang290 5 лет назад

@@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.

@danielbedrossian5067 5 лет назад

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.

@r3v3rbrobotics35 5 лет назад

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

@sacchar1n3 5 лет назад

what releases the tension on the rubber bands to fold it out?

@jonathanhuang7364 4 года назад

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.

@timothywalsh6660 4 года назад

@zachrutten 5 лет назад

@paceylandon2158 5 лет назад

could you change the robot so you only need to have one motor on the intake?

@jonathanhuang7364 5 лет назад

@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.

@boss_444 4 года назад

@@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?

@boss_444 4 года назад

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

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.

@arlomaguire7363 4 года назад

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
