27.4.3. Motion and Positioning Sensors

Try these first

1. 1.

   What does IMU stand for?

   Hint

   Think about sensors that measure motion.

2. 2.

   What technology helps robots know their location outdoors?

   Hint

   What satellites help with navigation?

3. 3.

   What does SLAM stand for?

   • Single Location And Mapping
   • Simultaneous Location And Mapping
   • Simultaneous Localization And Mapping

   Hint

   Focus on what happens at the same time with maps.

4. 4.

   True or False: IMUs are not effective in areas without GPS.

   • True
   • False

   Hint

   Think about how IMUs measure something besides location.

5. 5.

   Design a robotic mission for a post-earthquake scenario using IMUs, GPS, and SLAM. Outline the objectives and the interactions among the sensors.

   Hint

   Focus on how each sensor's capabilities support the mission goals.

6. 6.

   Discuss the limitations faced by GPS in urban environments during disaster scenarios and the role of IMUs in overcoming those limitations.

   Hint

   Consider the physical obstacles and how IMUs compensate when GPS fails.
