Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). In python, write a program whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: bob is a palindrome Ex: If the input is: bobby the output is: bobby is not a palindrome Hint: Start by removing spaces. Then check if a string is equivalent to its reverse.

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…
