why isnt my intake moving upwards for purple. instead, the second it hits the rubber band it stops.
it can intake green but not purple.
any suggestions?
will send picture if necessary.
Hi, it’ll probably be a good idea to show a picture since we can’t really determine anything without seeing how your intake works in the first place.

Your Intake is probably too low to the ground. Will send more information out, as soon as possible.
I have the same issues with my robot, but one of the other teams at my school is using a motor to move the flywheel up and down. I basically gave up on the rubber band movement bc it stopped collecting green cubes so now mine is stationary
You might need to rework your 4 bar linkage. Remember the linkage needs to move up and forward. So if the forward movement it’s too much, it actually has to push the purple block forward before it can go upwards. I suggest you test a few different 4 bar linkage positions to see which works the best for your robot.
Cheers.
Also, just noticed, it looks like your intake is stationary. LMK if I’m wrong tho.
Having the same issue here. We created a mechanism for the rotators to move up, but they don’t move up when in contact with purple blocks. We tried moving the intake 1 hole up, but then they can’t pick up green and only purple. I will post pictures soon. Our competition is in a week, so please help if you can.
Last year’s hero bot for VRC Spin Up had something called a “roving intake” that would move up and down to accomodate disks.
Maybe you could do something similar, having your intake move back and forth to accomodate the larger blocks.
So this is what I was explain in my previous post. The top diagram, you can see the intake needs to move forward before it moves upwards because the initial starting position of the intake is relatively close to the robot and intake back wall.
Where as the second diagram, the forward motion is much less and most of the movement is upwards.
So you will need to play around with the arrangement of your 4 bar to give you optimal outcome.
To push this idea further is if the linkage of the 4 bars is exactly perpendicular to the back wall in its starting position, intake will move up instantly without any forward movement at all when it intakes a purple. Not saying this is the solution but worth a try so you understand how the angles and arrangement of the bar is important variable the kids must need to investigate and test.
I hope that helps.
Cheers.

I’d do the linkage bars shorter and just have the intake go out a little bit farther out.
