Make sure your code lints with Ruff Linter
Include docstrings and comments to Google standard
Use appropriate function and variable names
Try to use type hints

Data structures

Design a system where a robot moves forward in a straight line until it detects an obstacle within 0.5 meters, then stops. Inputs: distance sensor data. Outputs: motor commands.
Design a system that tracks items entering and leaving a space (like a fridge). Inputs: door sensor, weight sensors on shelves, barcode/RFID readings. Outputs: current inventory list, alerts for low items.
Design a robot that maintains a constant distance (2 meters) behind another moving robot. Inputs: visual tracking data of leader position, own velocity. Outputs: motor commands to maintain distance.
Design a system where a robot maps a room's dimensions while avoiding obstacles. Inputs: LIDAR/depth sensor data, wheel odometry. Outputs: 2D room map, movement commands.
Design a robot that monitors a traffic light and crosses when green. Inputs: camera feed of traffic light, distance sensor data. Outputs: movement commands, current state (waiting/crossing).
Design a system where a robot arm picks up cubes from a defin

Testing

This is what a simple python test would look like:

def add_numbers(a, b):
    return a + b

def test_add_numbers():
 assert add_numbers(2, 2) == 4

Word Combination Challenge

You are given an input string in the format "target_word: subword1, subword2, ... subwordN" where:

The target word appears before the colon
After the colon is a comma-separated string of subwords

Write a function that determines if the subwords can be combined in any order to create the target word. If possible, return the combination with all vowels removed.
