-    "## Robot movement\n",
-    "\n",
-    "Simulate the movement of a robot in a two-dimensional integer grid. The robot can perform three actions: turn left, right, or move for 1 step in the direction it is facing. The robot receives instructions in the form of strings composed entirely by the letters `L, R, M` (meaning \"turn left\", \"turn right\" and \"move 1 step forwards\"). Write a function `move_robot(u0, instructions)` which receives as input:\n",
-    "\n",
-    "1. The robot's starting position `u0`, a tuple of `(x::Int, y::Int, d::Char)`, where `x, y` encode the starting position, and `d` the orientation, which can be a character of `'N', 'S', 'E', 'W'`.\n",
-    "2. The instructions which is a string sequencing the individual instructions, e.g., `\"LLMMMRMMRM\"`.\n",
-    "\n",
-    "The function should return `uf` which the robot's final position, which is a tuple of same type as `u0`.\n",
-    "\n",
-    "Test your function with the inputs `u0 = (7, 3, 'N')` and `instructions = \"RMMLML\"`, which should output `uf = (9, 4, 'W')`.\n",
-    "\n",
-    "_Hint: one way to solve this exercise is with lots and lots of `if` statements. Another is to create 2-tuples of movement vectors for each possible orientation. For rotation commands, the orientation vector gets updated. For movement commands, the oriantation vector is added to current position_"
