This design ties into my original design called “the conveyor to heaven”. This is for the 2nd half of the conveyor belt.
So the mechanism that will extend the 2nd half of the conveyor belt is what I call an “adjustable inclined plane”. I got the idea from a math concept (how you find the hypotenuse of a right triangle). The way it would work is that there are two sliding rails. One is level with the top of the robot, the other is connected to the conveyor belt. As the truck on the bottom moves closer to the 2nd rail, the truck on that 2nd rail is lifted up. I can’t explain it clearly, but hopefully the pictures show you what I mean.
