First, I suggest that you formulate a general strategy. How are you going to get the spuCraft to latch onto the payload? As described in the video, you need to hold the payload a fixed distance from Pokey while Pokey and the payload are going at exactly the same speed.
How are you going to do that?
You may remember that the input for the Drop world was the thruster force. Do you know what the input for the Lift world is? If not, I want you to go to the spuPilot and find out what it is.
