Questions & Answers

Q: What are the core problems in robotics?

The core problems in robotics include localization, planning, and manipulation. Localization refers to knowing the robot's position, planning involves creating paths to navigate, and manipulation focuses on the robot's ability to interact with objects.

Q: How do robots perceive and build maps of the world?

Robots use various sensors, such as RGB cameras, infrared depth cameras, and LiDAR, to perceive the world and measure distances. By continuously observing and tracking their own path, robots can update their mental maps of the world.

Q: What is simultaneous localization and mapping (SLAM)?

SLAM is a process in which robots simultaneously track their position and update their mental map of what they see. It allows robots to explore and navigate unknown environments while building an accurate map.

Q: How do robots plan actions?

Robots plan actions by considering different possible sequences of actions, their preconditions (current state of objects in the world), and their effects (how those objects will change). Planning involves reasoning through various routes to achieve a specific goal.

Summary & Key Takeaways

• Robotics is the science of building robots that can move and interact with the world, and it involves specific tasks and requirements for hardware and learning.

• Localization and planning are fundamental aspects of robot functionality as they involve knowing the robot's position and mapping the environment, which allows for efficient navigation.

• Manipulation refers to the mechanical abilities of a robot, including how it can interact with objects in the world, and it can be improved through proprioception and closed-loop control.
