Program Review: Cargo Retrieval

The program shown below is a sample solution to the Cargo Retrieval Mini-Challenge from Moving Forward 4. The program makes the robot move forward, retrieve a cargo box that is 50 cm away, then return home with it.
It assumes that the robot starts out with its arm raised all the way up.

Hover on any block in the program to view a detailed explanation.

1_Forward_Block Moves the robot forward 2.5 rotations at 50% power. The robot drives forward towards the object.

2_MoveMotor_Blah Moves the arm motor for -90 degrees. This lowers the robot's arm onto the object, assuming the arm was raised all the way up in the beginning.

3_Backward_Block Moves the robot backwards 2.5 rotation at 50% power. The robot drives backwards to bring the object back to the beginning.
