– Velocity = derivative of the position vector, a 3x1 vector
to get the vehicle going to where it should be
going
– Turn right / left
– Go up / down
– Speed up / slow down

Example
• Getting from AA building to Tainan Train Station
– How would you tell someone how to get there?
– How would you tell a robot to get there?
– Ad Hoc system (“starting from AA building you go 1 block…”)
• Most of our work in this class is going to be with
the Navigation problem (c)Shau-Shiun Jan, IAA, NCKU

Navigation and Guidance
• A set of parameters describing the position, velocity, altitude… of a vehicle
• Navigation state vector:
– Position = 3 coordinates of location, a 3x1 vector
