“I'd rather read the prompt

Clayton Ramsey - 2025-05-03

When I grade students’ assignments, I sometimes see answers like this:

Utilizing Euler angles for rotation representation could have the following possible downsides:

• Gimbal lock: In certain positions, orientations can reach a singularity, which prevents them from continuously rotating without a sudden change in the coordinate values.
• Numeric instability: Using Euler angles could cause numeric computations to be less precise, which can add up and produce inaccuracies if used often.
• Non-unique coordinates: Another downside of Euler angles is that some rotations do not have a unique representation in Euler angles, particularly at singularities.

The downsides of Euler angles make them difficult to utilize in robotics. It’s important to note that very few implementations employ Euler angles for robotics. Instead, one could use rotation matrices or quaternions to facilitate more efficient rotation representation.

Not a student’s real answer, but my handmade synthesis of the style and content of many answers]

You only have to read one or two of these answers to know exactly what’s up: the students just copy-pasted the output from a large language model, most likely ChatGPT.”
