"Water" Pump
This demonstrates a critical robotics function--transforming rotational motion into linear motion. The rotation of the piston, which is constrained at the top, forces the blue bricks to move upwards. The topmost brick falls out of the pump when the piston reaches its apogee. When FLL team members analyze this mission, they will discover a technique that may give them inspiration for their robot.
Here the piston is constrained to partial movement. This is just enough to let the first "water" brick fall out. The orange handle should be pushed slowly forward, moving the water up and ejecting the topmost brick. If the robot is too aggressive in pushing, the handle can flip up, which would make the device more difficult to activate. Also, the handle can be grasped by the robot and pulled forward until it stops, also ejecting the "water" brick.
Completed condition: the blue "water" brick touching the mat. Points would be in the 10-30 range, as this is a moderately easy task to solve.
