FLLCasts Tip

The mission model is close to home and is oriented so the robot can approach it directly. One solution is a mechanism that catches one of the red handles and pulls it twice to flip the rock; a rotating “harvester”-style mechanism could perform both pulls in one rotation.

A faster partial solution is to use an aligner and a protruding axle. As the robot approaches, the axle can enter the model and push the Research Flag down, after which the robot can return to home immediately. This can save a significant amount of match time.
