Challenges in Sensing, Communication, Coordination

Group 1

What are the main challenges?

• moving decisions on board
• implicit communication/ without medium
• local communication
• how to control / monitor the distributed process "there is a human in the loop"

Group 3

What are the main challenges?

• limited payload
• processing power
• (self-)localization
• coordination, synchronization of sensing
• communication (range, loss)
• collision avoidance
  • should work in worst case scenario (multiple UAVs, obstacles, communication outage)
• robustness, handling of every possible situation
• must be fail-operational to maintain safe state (situation-dependent)

What are the best suitable sensors, communication modules for small-scale UAVs? What is available?

• sensors
  • cameras
  • ultrasonic (for indoor, needs to be de-synchronized
  • infrared
  • contactsensors
  • LIDAR
  • IMU
  • GPS
  • wind sensor
  • barometric height sensor
  • sensing earth magnetic field

• communication modules
  • radio, e.g., X-Bees
  • IR
