Relative navigation and control of a hexacopter

open access: yes2012 IEEE International Conference on Robotics and Automation, 2012
This paper discusses the progress made on developing a multi-rotor helicopter equipped with a vision-based ability to navigate through an a priori unknown, GPS-denied environment. We highlight the backbone of our system, the relative estimation and control.

Control of rodent and human spatial navigation by room and apparatus cues [PDF]

open access: yes, 2009
A growing body of literature indicates that rats prefer to navigate in the direction of a goal in the environment (directional responding) rather than to the precise location of the goal (place navigation).
