Creating a Flowchart-Mechanical Man

Create a Flowchart

Construct a flowchart for an algorithm to make a mechanical man, who is
sitting in a chair facing a wall: 1) stand up, 2) walk to the wall and
touch it and 3) return to his chair and sit down.

The mechanical man possesses the following properties:

1. He is restricted to a limited set of operations.

2. He is event-driven (doing nothing unless given a specific
instruction).

3. He must carry out instructions one at a time.

4. He understands the following instructions:

a. Physical movement:

(1) Stand

(2) Sit

(3) Take one step forward

(4) Raise arms straight ahead

(5) Lower arms to sides

(6) Turn right (90 degrees without taking a step)

b. Arithmetic:

(1) Add one to a running total

(2) Subtract one from a running total

(3) Store a total (any number to totals can be stored)

c. Logic:

The mechanical man can decide what instruction he will carry
out next on the basis of answers to the following questions:

(1) Arithmetic results

(a) Is the result positive?

(b) Is the result negative?

(c) Is the result zero?

(d) Is the result equal to a predetermined amount?

(2) Physical status

(a) Are the raised arms touching anything?
