Welcome to your interview.
The question is on your right: Energy-Efficient Robotic Arm Paths. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you approach the optimization of a robotic arm's movement path to minimize energy consumption?
