Awesome!! thanks for the information! this really helps!! love your robot! One last thing what are the speeds of each roller?
the speeds are really up to you, I recommend 1000-1500 rpm for the top roller, and 400-600 rpm for the rest rest
How do you descore from the middle goal? Do you use the poking method or do you wrap your intakes around the posts?
perfect, thank you! that helps.
in the video you can see the intakes can wrap around for active descoring, but if I wanted to I could poke as well. I prefer actively descoring though because you can grab the balls, it’s faster, and you can score at the same time.
i see. I use the same method but am unable to descore the middle goal if the ball is in the opposite end of the goal, do you encounter the same problem?
no, the trick is to have the intakes stick in deep enough.
@Xenon27, I approve of the music. Still feel. is a great song, half alive is a really good band.
I agree.
Also totally unrelated, thanks so much @Xenon27 for making this reveal and introducing me to half alive. They are absolutely incredible. I’ve been really loving TrusT lately.
Seriously, I watched your reveal like 30 times because of how the music just kinda synced up and the camerawork at the beginning just totally fit the music. Good GOOD stuff!
@Xenon27 Did you ever have the issue where if you’re shooting more than 1 ball back to back, the balls hit each other in mid-air or near the goal? We have this issue right now and what happens is the second ball transfers all its speed to the first ball so it doesn’t quite make it into the goal. I guess one way to solve this is by staggering the balls when shooting which your robot does very nicely at around 29 seconds(there is quite a bit of distance between the balls so they’re not right next to each other). Any suggestions to help fix this? Btw great bot!
this is one of the biggest issues with hoodbots it seems. the trick is to get the perfect launch angle so that the balls go straight in without hitting the rim. a steeper angle seems to help as well.
you could also try a portable backboard or a 180 degree hood to make sure the balls all go into the goal.
@Xenon27 Do you have any plans on putting tracking wheels with the suspension to get an accurate reading for autonomous and if you are not could you explain why in a very in-depth way because I feel like they are necessary due to wheel slippage and stuff when you start moving faster in auto or just having an error on the field and the suspension fixing that reading for you
Also, @Xenon27 Why do you have your intank flip out? I have seen a robot that has their intank somehow built-in their robot and somehow it looks like the same size as your robot. Do you plan on changing that or what?
not in the immediate future, no.
There probably won’t be competitions in socal possibly for the entire season and I don’t have room for a full field so I can’t grind out skills.
but if things were normal I totally would be pursuing position tracking with tracking wheels so I’d encourage others to try it.
in order to fit in sizing and to give them a pivoting suspension which helps with compression and allows me to actively descoring center goals.
my robot is quite lengthy when fully deployed, well out of 18", so that’s not possible. you can have static intakes if you make your robot shorter like MJS does. But I like the flipout because it gives me that pivoting flexibility and I don’t have to worry about the length of the robot.
Ah, thanks! What is happening is exactly what you described. The first ball hits the rim near the bottom of the backboard and the second ball hits the first and bounces off. I think if I increase the hood angle it should help. Thanks!
As xenon said if you can tune your hood and launch angle that would help. Try to get the launch to be in more of the center of the opening instead of the rim
cool design. i’ve been seeing a lot of this:
agree but I hate rubber bands. Rubber bands are satan. Treads are also satan. Intakes in general are satan.
why i hate intakes
idk, im not the one that builds them
ethan hyped up his compliance wheel intakes long before the flex wheels became vrc legal. flex wheels are likely now the best intake roller choice. (unless you have better compliance wheels than even those ethan
)
How do you lock your intakes in place/deploy them? I have been trying to come up with a way to do that passively, but I am kind of stuck.
I just sort of got lucky in the spacing where I can just fold them back and the friction between them and the wheels on my drive is enough to hold them in place. when they spin, it kind of dislodges them and they’re free to swing forward.
if you don’t have that though, I would suggest maybe adding something that sticks out to rub on the intakes to do that same thing. Alternatively you could probably have some kind of catch on the rollers that when they spin for the first time it releases from some other thing that was holding the intakes back.
