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 if the robot is at a wall.You do this via the boolean conditions "at wall" or "not at wall".The following are examples of this:
if at wallif not at wallwhile not at wall
AssumptionsYou 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…
Create a simple machine problem that shows:Pass by value and pass by reference.

- What is the term for an algorithm that is more time efficient but less space efficient?arrow_forwardWrite a graphical program to trace a random walk (see previous two prob-lems) in two dimensions. In this simulation you should allow the step to be taken in any direction. You can generate a random direction as an angleoff of the x axis. angle = random() * 2 * math.piarrow_forwardWrite an algorithm that prompts the user for the radius, in inches, and price of a pizza, and then reads in those values. Finally, have the algorithm compute and output the pizza’s cost per square inch.arrow_forward
- In order to transform a problem into an algorithm, we need the term "computer programme," which is nothing more than a phrase.arrow_forwardWhat is the difference between a heuristic and an algorithm ?arrow_forwardGiven two variables A and B, with integer values, write an algorithm that changes the values of the variables, without creating a new variable.ex: A = 3, B = 5 -> A = 5, b = 3)arrow_forward
- How would you define an algorithm if you had to do it yourself?arrow_forward(python) Write the program based on the details in the picture and the additional details below. Since this is a simulation, we will not prompt the user for inputs. Any inputs will result in a loss of points. To determine the radius of the circle, add together your Birth Month and Day. So my radius would be 41. NOTE: this radius will be used for all of the simulation trials. Once you have the radius, implement the Monte Carlo simulation with 500,000 random (x,y) points (remember to make them floats) and display the results of 10 trials. Each trial does another simulation of 500,000 random (x,y). Display the following for each trial: Trial number Number of hits inside the circle from the simulation The percentage of hits (Only want 2 decimal places) At the end you must display the average percentage for all 10 trials. Bonus Option: Create an 11th trial and create a graphic representation of the simulation.
