Rules:
Modified 6x6 Sudoku rules apply: Place the digits 0-5 in every row, column, and box.
Draw a path along interior gridlines starting from the robot and ending on one of the green circles. The path cannot touch itself.
The robot computes the sum of each pair of digits it passes between, and writes these sums to the grey memory cells in reading order. (All memory cells must be written to).
Solution code: Memory cells that don't touch the path (even diagonally)

I did not find it that easy, especially when starting out. But it was really interesting to figure out the implications of the ruleset and it is a fun use of 0-5. Thank you for the nice puzzle, Nordy!
