My robot has been getting stuck on the discs and I can’t get off unless my teammate pushes me, but what if they get stuck as well. does anyone know what to do?

Maybe design barriers to prevent discs from going on in the first place? I’ve seen this happen in every game. Each team needs to work the problem through.
Do note down side is if you have disc under robot it can count as possession limit. So be careful of such situations.

you can either make it harder to get stuck in the first place, or easier to get unstuck.
a very low riding robot will be less likely to have a disc go under the bot, if you use skirts and low hanging bracing on the edges of your drive, especially around the wheels, discs will be pushed instead of driven over. But this can make it harder to get off a disc if you do get stuck, which can still happen in situations where the robot bucks around or is pushed onto a disc.
A robot with high clearance will be more likely to roll over discs, but might also be able to get off of them more easily. Of course, wheels still need to touch the ground, but if you design a robot in such a way that the wheels are the only thing that makes contact with discs, even when driving over them, you will likely be able to just drive over discs instead of being stuck. But at the same time, this isn’t exactly possible since you need to be able to intake and funnel discs, which usually requires a low riding funnel or ramp of some kind. Things like using 6 or even 8 wheeled drives can also be helpful if you find the robot is getting stuck on a disc on one side in the deadzone between wheels.
So it’s not a very simple issue, and one you’ll have to do a lot of design around if you find it being problematic. One good place to start might be to see if you can spot any areas of the robot that seem to get stuck on discs often, and think of ways to modify that particular point.

Strange, I didn’t know this was a serious issue. My team can’t get stuck on one during practice when we are trying.
A few options are available, one is to add skirts (Metal or polycarb) that will protect the wheels.
The other common option is to raise the robot so that you simply drive over the discs.
My teams can drive over the discs, but we still have skirts to protect the wheels and gears.
Skirts can also protect the discs from being shredded up by your gears
This is a serious issue in games that have anything the robot can run over. Take, for example, last year’s competition. I saw countless teams have a wheel stuck in a ringle, something that would usually mean that team losing the match, regardless of their skill level. Getting stuck on objects can destroy a robot’s mobility, so it’s always something to consider.
Here is an example of some simple metal skirts (don’t mind the brain and keeps nuts, old pic)

Our team had issues with ringles last season, but this year we don’t struggle with discs at all.

Our team just put a bunch of standoffs in front of the places it can get stuck, works for us ¯_(ツ)_/¯
