Sensor suite (LiDAR, radar, camera) in EV Technology - Mini Project: Build & Apply

Sensor suite (LiDAR, radar, camera)

📖 Scenario: You are working on an electric vehicle (EV) project that uses a sensor suite to detect obstacles and navigate safely. The sensor suite includes LiDAR, radar, and camera sensors. Each sensor has specific properties like range, resolution, and type.

🎯 Goal: Build a simple data structure to represent the sensor suite, configure a threshold for detection range, filter sensors that meet the threshold, and finalize the sensor list for the EV system.

📋 What You'll Learn

Create a dictionary named sensor_suite with three sensors: LiDAR, Radar, and Camera.

Each sensor entry must be a dictionary with keys: type, range_meters, and resolution.

Add a variable min_range to set the minimum detection range threshold.

Use a dictionary comprehension to create a new dictionary active_sensors with sensors having range_meters greater than or equal to min_range.

Add a final key status with value "active" to each sensor in active_sensors.

💡 Why This Matters

🌍 Real World

Electric vehicles use sensor suites like LiDAR, radar, and cameras to detect obstacles and navigate safely.

💼 Career

Understanding how to organize and filter sensor data is important for roles in automotive engineering, robotics, and autonomous systems.

1

Create the sensor suite dictionary

Create a dictionary called sensor_suite with these exact entries: 'LiDAR', 'Radar', and 'Camera'. Each sensor should be a dictionary with keys and values exactly as follows: type: 'distance', range_meters: 100 for LiDAR, 200 for Radar, 50 for Camera, and resolution: 'high' for LiDAR, 'medium' for Radar, 'low' for Camera.

# Create the sensor_suite dictionary with LiDAR, Radar, and Camera
# Your code here

Need a hint?

Use a dictionary with keys as sensor names and values as dictionaries with the specified keys and values.

2

Set the minimum detection range threshold

Add a variable called min_range and set it to the integer value 100 to represent the minimum detection range in meters.

EV Technology

sensor_suite = {
    'LiDAR': {'type': 'distance', 'range_meters': 100, 'resolution': 'high'},
    'Radar': {'type': 'distance', 'range_meters': 200, 'resolution': 'medium'},
    'Camera': {'type': 'distance', 'range_meters': 50, 'resolution': 'low'}
}
# Set the minimum detection range threshold
# Your code here

Need a hint?

Just create a variable named min_range and assign it the value 100.

3

Filter sensors by minimum range

Use a dictionary comprehension to create a new dictionary called active_sensors that includes only sensors from sensor_suite where the range_meters value is greater than or equal to min_range.

EV Technology

sensor_suite = {
    'LiDAR': {'type': 'distance', 'range_meters': 100, 'resolution': 'high'},
    'Radar': {'type': 'distance', 'range_meters': 200, 'resolution': 'medium'},
    'Camera': {'type': 'distance', 'range_meters': 50, 'resolution': 'low'}
}

min_range = 100

# Create active_sensors dictionary with sensors having range_meters >= min_range
# Your code here

Need a hint?

Use a dictionary comprehension with for name, details in sensor_suite.items() and filter by details['range_meters'] >= min_range.

4

Add status to active sensors

Add a key 'status' with the value 'active' to each sensor dictionary inside active_sensors.

EV Technology

sensor_suite = {
    'LiDAR': {'type': 'distance', 'range_meters': 100, 'resolution': 'high'},
    'Radar': {'type': 'distance', 'range_meters': 200, 'resolution': 'medium'},
    'Camera': {'type': 'distance', 'range_meters': 50, 'resolution': 'low'}
}

min_range = 100

active_sensors = {name: details for name, details in sensor_suite.items() if details['range_meters'] >= min_range}

# Add 'status': 'active' to each sensor in active_sensors
# Your code here

Need a hint?

Use a for loop over active_sensors.values() and add the key 'status' with value 'active' to each sensor dictionary.
