Arena start location

The info is in the arena's gmf. After you decompile it, just 'search' for the below text ""GMID_ATTACHMENTPT" (there are 4 starting points, below is starting point 1):

   *GMID_ATTACHMENTPT
   {
   *NODE_NAME Point01
   *NODE_TM
   {
   *NODE_NAME Point01
   *TM_ROW0 0 0 -1
   *TM_ROW1 0 1 0
   *TM_ROW2 1 0 0
   *TM_ROW3 -17 1 12   <-- This ROW X Y Z
   }
   USER DATA type = startpoint
   id = 1
   }

Just edit the X and Z positions (center is Y) until you get it to start where you want.

(PS: the indenting in the gmf must be kept as is)

to change how high the robot starts just adjust the Y parameter in the said triad.
