Path Planning
Path Planning is a key skill in robotics where specialists design how robots move from one point to another while avoiding obstacles. Think of it like creating a GPS navigation system, but for robots moving in factories, warehouses, or other spaces. This involves figuring out the best and safest route for robots to follow, whether they're moving materials in a warehouse, assembling cars in a factory, or even exploring other planets. Related terms you might see include "motion planning," "route optimization," or "trajectory planning." This is a fundamental part of making robots work efficiently and safely in real-world environments.

Example Interview Questions
Senior Level Questions
Q: How would you approach implementing path planning for a robot working in a dynamic environment with moving obstacles?
Expected Answer: A senior engineer should explain approaches for real-time path adjustment, safety considerations, and how to balance efficiency with reliability. They should mention examples from previous projects and how they handled unexpected situations.
Q: What strategies would you use to optimize path planning for multiple robots working in the same space?
Expected Answer: Should discuss coordination between robots, collision avoidance, priority handling, and how to maintain efficiency when multiple robots are operating simultaneously.
Mid Level Questions
Q: Can you explain different path planning algorithms and when you would use each one?
Expected Answer: Should be able to explain basic approaches in simple terms, comparing their benefits and drawbacks in different situations, like indoor vs outdoor environments or simple vs complex spaces.
Q: How do you ensure safety in robot path planning?
Expected Answer: Should discuss obstacle detection, emergency stops, speed control, and how to implement safety zones around humans and sensitive equipment.
Junior Level Questions
Q: What is the difference between global and local path planning?
Expected Answer: Should be able to explain that global planning is like planning the overall route on a map, while local planning handles immediate obstacles and adjustments, similar to how we navigate while walking.
Q: How would you test if a path planning solution is working correctly?
Expected Answer: Should mention basic testing approaches like simulation, checking for collisions, measuring completion time, and ensuring the robot reaches its goal reliably.
