Mission upload and execution in Drone Programming - Mini Project: Build & Apply

Mission upload and execution

📖 Scenario: You are programming a drone to perform a simple mission. The drone needs to fly to specific GPS coordinates in order, hover for a moment, and then move to the next point. This project will guide you through uploading a mission with waypoints and executing it step-by-step.

🎯 Goal: Build a program that uploads a list of GPS waypoints as a mission to the drone and then executes the mission by flying to each waypoint in order.

📋 What You'll Learn

Create a list of GPS waypoints with exact coordinates

Set a mission name variable

Write a loop to upload each waypoint to the drone

Print the mission execution status after flying all waypoints

💡 Why This Matters

🌍 Real World

Drones often need to fly specific routes for tasks like surveying, delivery, or inspection. Programming missions with waypoints is a common real-world task.

💼 Career

Understanding how to upload and execute missions is important for drone operators, robotics programmers, and automation engineers.

1

Create the mission waypoints list

Create a list called mission_waypoints with these exact GPS coordinates as tuples: (34.0001, -117.0001), (34.0002, -117.0002), (34.0003, -117.0003).

Drone Programming

# Your code here

Hint

Use a list with tuples for each GPS coordinate.

2

Set the mission name

Create a string variable called mission_name and set it to "Test Flight 1".

Drone Programming

mission_waypoints = [(34.0001, -117.0001), (34.0002, -117.0002), (34.0003, -117.0003)]
# Your code here

Hint

Use a simple string assignment.

3

Upload each waypoint to the drone

Use a for loop with variable waypoint to iterate over mission_waypoints and call upload_waypoint(waypoint) inside the loop.

Drone Programming

mission_waypoints = [(34.0001, -117.0001), (34.0002, -117.0002), (34.0003, -117.0003)]
mission_name = "Test Flight 1"
# Your code here

Hint

Use a for loop to send each waypoint to the drone.

4

Execute the mission and print status

Call execute_mission() and then print exactly "Mission Test Flight 1 completed successfully." using the mission_name variable.

Drone Programming

mission_waypoints = [(34.0001, -117.0001), (34.0002, -117.0002), (34.0003, -117.0003)]
mission_name = "Test Flight 1"
for waypoint in mission_waypoints:
    upload_waypoint(waypoint)
# Your code here

Hint

Call the execute function and print the message using an f-string.

Practice

1. What does uploading a mission to a drone usually do?

easy

A. It immediately starts the drone's engines.

B. It charges the drone's battery.

C. It returns the drone to its home location.

D. It sends the flight plan to the drone for automatic flying.

Solution

1. Step 1: Understand mission upload meaning

   Uploading a mission means sending the flight plan to the drone's system.

2. Step 2: Identify what happens after upload

   The drone receives the plan but does not start flying until commanded.

3. Final Answer:

   It sends the flight plan to the drone for automatic flying. -> Option D

4. Quick Check:

   Uploading mission = send flight plan [OK]

Hint: Uploading means sending the flight plan, not starting flight [OK]

Common Mistakes:

• Confusing upload with starting the drone
• Thinking upload charges the battery
• Assuming upload returns drone home

2. Which of the following is the correct syntax to start a mission after uploading it in drone programming?

easy

A. drone.startMission()

B. drone.uploadMission()

C. drone.beginFlight()

D. drone.executePlan()

Solution

1. Step 1: Identify method to start mission

   The method to start flying the uploaded mission is usually named startMission().

2. Step 2: Differentiate from upload method

   uploadMission() uploads the plan but does not start flight.

3. Final Answer:

   drone.startMission() -> Option A

4. Quick Check:

   Start mission method = startMission() [OK]

Hint: Start mission uses startMission(), not uploadMission() [OK]

Common Mistakes:

• Using uploadMission() to start flight
• Confusing method names like beginFlight() which is invalid
• Assuming executePlan() is standard method

3. Given this code snippet:

drone.uploadMission(missionPlan)
drone.startMission()
print(drone.status())

What is the expected output if the mission starts successfully?

medium

A. "Mission started"

B. "Mission uploaded"

C. "Mission completed"

D. "Error: No mission uploaded"

Solution

1. Step 1: Analyze code sequence

   The mission is uploaded first, then started, so the drone should be flying.

2. Step 2: Check status output meaning

   Calling drone.status() after startMission() should return "Mission started" indicating flight began.

3. Final Answer:

   "Mission started" -> Option A

4. Quick Check:

   Status after startMission() = "Mission started" [OK]

Hint: Status after startMission() shows "Mission started" [OK]

Common Mistakes:

• Confusing upload status with start status
• Expecting "Mission completed" immediately
• Assuming error without upload

4. Identify the error in this code snippet:

drone.startMission()
drone.uploadMission(missionPlan)

medium

A. Missing drone initialization causes failure.

B. Uploading mission twice is not allowed.

C. Starting mission before uploading causes an error.

D. No error; code runs fine.

Solution

1. Step 1: Check order of operations

   Mission must be uploaded before starting; here startMission() is called first.

2. Step 2: Understand consequence

   Starting mission without upload means no flight plan, causing an error.

3. Final Answer:

   Starting mission before uploading causes an error. -> Option C

4. Quick Check:

   Upload before startMission() [OK]

Hint: Upload mission before starting flight to avoid errors [OK]

Common Mistakes:

• Calling startMission() before uploadMission()
• Assuming no initialization error
• Thinking multiple uploads cause error here

5. You want to upload a mission and monitor its progress until completion. Which code sequence correctly achieves this?

1. drone.uploadMission(plan)
2. drone.startMission()
3. while not drone.isMissionComplete():
       print(drone.getProgress())
4. print("Mission complete!")

hard

A. Mission cannot be monitored programmatically after upload.

B. This sequence correctly uploads, starts, monitors, and confirms mission completion.

C. The loop should check drone.status() == "started" instead of isMissionComplete().

D. You must call drone.monitorMission() before startMission().

Solution

1. Step 1: Verify mission upload and start

   Uploading the plan then starting the mission is the correct order.

2. Step 2: Confirm monitoring loop logic

   The loop checks if mission is complete and prints progress until done, then confirms completion.

3. Final Answer:

   This sequence correctly uploads, starts, monitors, and confirms mission completion. -> Option B

4. Quick Check:

   Upload -> start -> monitor -> complete [OK]

Hint: Upload first, then start, then monitor until complete [OK]

Common Mistakes:

• Trying to monitor before starting mission
• Checking wrong status in loop
• Assuming mission can't be monitored
