 Variable = is a value that may change within a given scope of a problem or equation  Examples = x, a, in our activity ATPICK  Programming = The action or process of writing computer programs

 Stacking multiple objects When objects are within even increments from each other Relative positions to original position  Laser cutter  Palletizing

 Teach positions (ATPICK)  Create a loop  Set desired positions as computation variables  Increment variables (ATPICK+1)  (IF) jump (end) and (JU) jump to

 Less positions needed to be taught  Faster programming
