The most familiar example is a car’s speedometer which measures the car’s speed by counting rotations of the wheels (Sect. Some of these projects [6,7] also use prior information, for example a map, to compare the current sensor readings, which produces a more accurate, robust and reliable localization. by our control computer (using a real-time operating system). Sensory stimuli (smell, vision, touch, taste, hearing and somatosensory signals) are processed together in the brain, triggering memories, expectations and also reward mechanisms that translate into food impulse/desire or refusal [ 3 ]. Furthermore, it is demonstrated how prior information about the spatial density of landmarks can be utilized in order to compute a tight upper bound on the expected covariance of the posi-tioning errors.

Walking, grasping and handling objects and eating are some of these core activities. • Exteroceptive sensors: sensors gathering information from the environment, like distance and/or angle to objects, light intensity reflected by the environment, etc. This exteroceptive input is combined with proprioceptive sensory data and is given to the neural network, which produces actuator commands. Passive sensors measure ambient environmental energy entering the sensor. Definition 7.1.2 (Exteroceptive). Stereo camera–based depth sensors, which most existing legged robots rely on ( 6 , 9 , 12 ), require texture to perform stereo matching and consequently struggle with low-texture surfaces or when parts of the image are under- or overexposed. The Exteroceptive Sensations Exteroceptive sensations originate in peripheral receptors in response to external stimuli and changes in the environment. Proprioceptive sensors measure values internal to the system (robot); for example, motor speed, wheel load, robot arm joint angles, and battery voltage.
