                  UAV: Unmanned aerial vehicle. The term UAV applies to systems with various degrees of autonomy, from remote
                  controlled aircraft to drones that fly themselves from takeoff to landing.

                  UCAV: Unmanned combat aerial vehicle. Like a UAV, except armed and dangerous.
                  UNCANNY VALLEY: A concept in robotics suggesting that if the appearance of a humanoid robot approaches but not
                  attains that of a human, that robot will elicit an uncomfortable reaction from people. In one word: creepy.

                  V
                  VICON: A company that manufactures motion tracking systems. Uses infrared cameras to very precisely track the
                  motion of tagged objects in precalibrated environments; commonly used to control quadrotors indoors.

                  W

                  WORKSPACE: If a robot can reach a point in space, said point is within the robot’s workspace. If a robot can’t reach a
                  point in space, you have to move the robot.
                  X

                  XYZ COORDINATES: The Cartesian coordinate system we know and love.

                  Y

                  YAW, PITCH, AND ROLL: Terms to describe motion along an aircraft main axes. A yaw motion moves the nose of
                  the aircraft from side to side. A pitch motion moves the nose of the aircraft up or down. A roll motion keeps the nose
                  straight while moving one wing up and the other down.
                  Z

                  ZMP: Zero moment point is a control method widely used with dynamic robots to help them maintain stability. It
                  positions the robot such that the ground contact point (like the bottom of a humanoid robot’s foot) has zero horizontal
                  motion.
