hi guys I need help with my graber bot im making 1rst problem: you know how a servo only turns 90 degrees from its starting point well I have a servo controling the gripper and when I close the gripper the gripper closes but the servo doesnt turn a whole 90 degrees because of how I set up the mechanism to close the gripper . Is there a way to stop the servo say like at60 degrees for example I mean I dont know how far it needs to stop but I was hoping I could fix this because when the servo doesnt turn all the way it gets really hot heres some pictures of my grabber and servo http://www.vexforum.com/gallery/showimage.php?i=501&c=8 http://www.vexforum.com/gallery/showimage.php?i=503&c=8 http://www.vexforum.com/gallery/showimage.php?i=502&c=8 http://www.vexforum.com/gallery/showimage.php?i=500&c=8
note there is nothing wrong with the servo and I do have a programming kit
also is there a way to have the servo stay in its position when I let go of the butten like channel 5 up button= gripper close and stay with out me holding it. bottom button opens gripper
ok one more thing I am using a program because i needed to use 2 motors to lift the arm my code is
tank mode with 2 motors
one motor on channel 1
2 motors on channel 4
1 servo on channel 5
I want to use some limit swithes to stop my arm from going to far but since im using a program I cant use the set up thats in the defalt program I want to have a limit switch so when the arm goes to high it will stop it from going higher but still bieng able to move down not just stop the arm from moving both ways basicly I need a code that is the same as the one for limit switches in the defalt
