Assess students' ability to apply loops, conditionals, and variables to design and implement a program that controls a simulated robot through a grid maze. Tasks include writing pseudocode or block-based code to move from start to goal, using loops to repeat movement patterns, conditionals to respond to walls and junctions, variables to track position/state and step counts, and strategies to handle dead-ends and avoid infinite loops. Evaluate correctness, use of control structures, state management, and simple optimization (fewer steps or clearer logic).
