Omnidirectional refers to the notion of existing in every direction. Omnidirectional devices include:

  • Omnidirectional antenna, an antenna that radiates equally in all directions
  • VHF omnidirectional range, a type of radio navigation system for aircraft
  • Omnidirectional camera, a camera that can see all 360 degrees around it
  • Omnidirectional treadmill, a treadmill that allows a person to walk in any direction without moving
  • Omnidirectional microphone, a microphone that can hear from all directions
  • Mecanum wheel, a specially designed wheel that allows movement in any direction, such as that used by many robots in the RoboCup Small Size League
