5: Sensors
( \newcommand{\kernel}{\mathrm{null}\,}\)
Robots are systems that sense, actuate, and compute. So far, we have studied the basic physical principles of actuation, i.e., locomotion and manipulation, and computation, i.e., inverse kinematics and path-planning. We now need to understand the basic principles of robotic sensors that provide the data-basis for computation. The goals of this chapter are
- provide an overview of sensors commonly used on robotic systems
- outline the physical principles that are responsible for uncertainty in sensor-based reasoning
