I was wondering if anyone knows why our base is stalling? And if so, how to fix it. We have the 3:1 sprocket ratio
There are many possible causes, answering some questions would help diagnose the problem. To me it sounds like it's due to the 3:1 gearing, but I'm not sure.
@Randor4478 If it is 3:1, I would put it back to 1:1. It is generally not good to gear wheels for speed as it often results in not enough torque for the wheels to move causing the base to stall
I agree. It's probably possible to get away with 3:1 torque with a light bot, but that isn't neccessary when HS and turbo are available. Not to mention the power loss due to chain.
How many motors are you dedicating to it? 3:1 is not that obscene of a ratio. I saw some teams get away with it in NBN. If you are not dedicating >= 6 motors on it, well there's your problem. If you are and it's still stalling, I would recommend weighing your robot and doing some basic stall torque calculations to figure out what weight you need to be at.
@Alpha Dream <3 we will try moving it back to a 1:1 sprocket ratio. Do you believe it is safe to put 6 total motors, 1:1 ratio, and high speed motors? or is the high speed motors too risky?
6 Motors with 1:1 high speed is definitely possible. You could even do Turbo motors with the same configuration. You could even do 4 Speed motors like lots of teams do. Just make sure to avoid friction and you'll be fine.
