My team decided to change their drivetrain to increase speed. It is a community team and I am a mom with no training or experience. Their only experience is with drive trains that have a 1:1 gear ration. They decided to try something new and switch to a chain and sprocket drive system. They built i a 2 motor drivetrain. The motors are on a 24 tooth sprockets and the wheels are on 16 tooth sprockets. When they drove the robot to test it, they noticed that sometimes the robot doesn’t respond to the input from the controller and we hear a whining. They turned the robot on its side to look for an area where it is rubbing and they don’t see anything obvious. They can’t find any consistencies in when it stops driving. Any ideas on how they can solve the problem? Is this their motors dying?
