I am stuck on exercises 2,3, and 4

Exercise 2 Rob sits in a chair four steps away from a table. A ball is resting on the table top. Using the least number of instructions from the Instruction Set list box, create an algorithm directing him to pick up the ball, and then returning him to his original position. Exercise 3 Rob faces a chair with its back to the wall. The chair is zero or more steps away from him. Using the least number of instructions from the Instruction Set list box, create an algorithm directing him to sit in the chair, but only if the chair is not broken. If the chair is broken, the algorithm should instruct him to fix the chair. Exercise 4 Rob sits in a chair facing a box zero or more steps away from him. He is holding a toy in his left hand. Using the least number of instructions from the Instruction Set list box, create an algorithm directing him to drop the toy in the box, but only if the box is not full. The algorithm should also return him to his original position.
