We are having a problem with getting the lift to be at the perfect height to get hexball off the fence in autonomous.
We have hold power on as soon as the lift is raised. Is that needed when you have 2 motors for the lift? Or should it be only when you have our 2 hexballs in the claw?
Is the inaccuracy of the lift because of an unnecessary hold power?
Thanks.
P.S. the lift is supposed to raise so many degrees
WHEN START
motor up 220*
motor speed 75%
motor hold power ON
that is for the left motor to lift and the right is the same except motor down 220* because they face each other. They are not bucking each other. Because in driver control the lift works.
should we not even have the motor speed set?
The commands are different in different programming languages, but all of them have some type of “Hold” concept, and yes you want it ON for a lift. If it is off then gravity will start pulling your lift back down as soon as it reaches the desired position.
The number of degrees will not be very accurate, so you will have to adjust that number. If your lift consistently moves to the same location, then all you need to do is find the right number.
If it is not always moving to the same position, then you probably just need to insure that your lift is always in the exact same position when you start the program. The position it is in when the program starts will be zero degrees.
Our lift had a slightly stripped gear that would get stuck in a specific spot during autonomous. The kids didn’t really notice it in driver control. They changed out the gear and the lift went to the correct height as programmed. Hope that is helpful.
