Robot Project
Programming
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 wall
if not at wall
while not at wall
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
Your pseudocode must conform to the course pseudocode guidelines.
Once you have completed the algorithm:
Make sure your comments are detailed enough, someone without any knowledge of algorithms or pseudocode could follow what is happening. Upload the assignment as a text document using the following naming protocol: flast-Project.txt where “flast” is the first letter of your first name followed by your last name.
