i'm new to electronic.
i have two rubber stick-on, i actually dont know what they are called. actually its a rubber, when push to a surface, it sticks there.. (actually, it removes all the air inside the round surface of the rubber and gets stick)
[see the image]
so i want to ask that how do i make the structure that the robot pushes the leg downward (toward the surface) so that the stick-on gets stick...?
i have an idea about how to stick it off... and that is, make a hole on the top of the rubber stick-on and put a cork which is removed (by a motor to let the air in) when we need to stick it off and then during sticking it, the cork is placed again so that air cannot be get inside the rubber.
thank you.
