Our team previously used a drivetrain with all gears last year. Anytime we would move one of the joysticks to move just one side or have both joysticks going opposite ways to basically spin around, we had great response/control. This year we are trying a drivetrain using chain and sprockets and our response/control is not very good at all in those scenarios. We get a lot of wheel spin or sometimes it’s sluggish to spin at all.
Is this a know disadvantage of using a chain/sprocket drivetrain?
I tried using a smaller sprocket on the one off the motor and that didn’t make a difference. The robot itself is pretty well balanced in weight, so I don’t feel that’s an issue. I don’t think the location of the motor/ sprocket would affect things based on other robot designs I’ve seen. I will say we don’t really have much issue when driving forward, AKA both motors going at the same time
