Trajectory Planning
Trajectory Planning is how robots figure out the best way to move from one point to another, like planning the safest and most efficient path. Think of it like planning a road trip - you need to know the route, speed, and timing. In robotics, this helps machines move smoothly whether they're assembling cars, picking items in warehouses, or working alongside humans. It's a key skill that robotics engineers use to make sure robots move safely and efficiently. Similar terms you might see include Motion Planning, Path Planning, or Robot Movement Control.

Example Interview Questions
Senior Level Questions
Q: How would you approach trajectory planning for a robot working in a dynamic environment with moving obstacles?
Expected Answer: A strong answer should explain how they would create systems that can constantly update movement paths to avoid collisions, balance speed with safety, and handle unexpected changes in the environment. They should mention real-world examples from their experience.
Q: What factors do you consider when optimizing robot movement paths in a manufacturing setting?
Expected Answer: Look for answers that discuss production efficiency, safety considerations, energy consumption, wear and tear on equipment, and coordination with other machines or humans in the workspace.
Mid Level Questions
Q: Explain how you would ensure smooth robot movements when planning trajectories.
Expected Answer: The candidate should discuss how they consider speed changes, acceleration limits, and movement transitions to prevent jerky or dangerous robot movements.
Q: What safety considerations do you implement in trajectory planning?
Expected Answer: They should mention collision avoidance, speed limits in human-occupied areas, emergency stop capabilities, and proper risk assessment procedures.
Junior Level Questions
Q: What is the basic purpose of trajectory planning in robotics?
Expected Answer: They should explain that it's about determining how a robot should move from start to finish, considering factors like speed, distance, and obstacles.
Q: What are the main differences between point-to-point and continuous path movement?
Expected Answer: Look for understanding that point-to-point focuses on start and end positions, while continuous path controls the entire movement route, like in welding or painting applications.
