Distance from key to bridge?

[Hebrew]

I am attempting to find the dimensions from the key to the bridge so I can program an autonomous program that will bring our robot to the bridge and lower it to save some time in teleop (Since we are a rookie team and have no shooter, just defense). Does anyone know the EXACT distance from the end of the key to the tip of the bridge?

Has anyone got a program working for this that they could PM me for reference (In labview) I am new to labview and am not sure I can get that done by Tuesday.

Thanks.
