Robot Algorithm

Your HW would be better if you included conditional statements such as if /else, if true then do something or if false do something else. With conditional statements you always need to have two possibilities. Never leave the computer hanging about what do next. Also, for counting the number of steps to the wall use a while statement.

This is the task:
Scenario: A robot is sitting in a chair with its arms facing down. Write an algorithm, using pseudocode, to make the robot:
stand up
walk until it senses a wall
turn around
walk back to the chair
sit back down in the origin starting position
Finally, output the total number of steps taken.
Commands:
In addition to our standard pseudocode commands, you must also use the following robot control commands:
sit
stand
step (one step forward)
raise arms (parallel to floor)
lower arms (pointing to floor)
sense (only if arms are raised)
turn (90 degrees right)
Immediately after issuing a sense command, you can check whether the robot is at the wall as follows:
if at wall
or alternatively
if not at wall
You should use comments, sequence, comparison, iterative instructions in this project.
Assumptions

You must assume the following facts:
The robot’s initial sitting position is directly facing the target wall.
There are no obstacles between the robot and the wall.
The wall is 1 or more exact steps from the chair.
The wall is sensed when it is less than 1 step from the robot’s arms.
The length of the robot’s arms are slightly less than the length of 1 step.
Your solution

Your solution must include all of the following:
Adequate comments
Initialization and use of at least one variable
Sequential flow of control
Conditional flow of control
Iterative flow of control
Handling of any special cases
Output of the total number of steps taken
