Question 1.
What does RRT* stand for?
Show hintHide hint
Think of RRT with an addition.
Question 2.
What is one main advantage of RRT* over RRT?
Show hintHide hint
Focus on optimization.
3Question 3.
What does RRT* improve upon compared to RRT?
- Reduces runtime
- Optimizes paths
- Increases complexity
Show hintHide hint
Focus on optimization.
4Question 4.
True or False: RRT* guarantees optimal paths for any sequence of samples.
- True
- False
Show hintHide hint
Consider the conditions of guaranteed optimality.
Question 5.
Consider a scenario where an RRT* algorithm is initialized in a cluttered environment with multiple moving obstacles. How would you implement a safety measure to ensure the drone avoids collisions while still optimizing its path?
Show hintHide hint
Link real-time data with pathfinding.
Question 6.
Discuss how RRT* would perform in a scenario where the environment changes dramatically after a few samples have been taken. What strategies can be discussed for adapting the current tree?
Show hintHide hint
Address adaptiveness in changing contexts.
