However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.
Odometry is the use of data from motion sensors to estimate change in position over time. It is used in robotics by some legged or wheeled robots to estimate their position relative to a starting location. This method is sensitive to errors due to the integration of velocity measurements over time to give position estimates.
Motion platforms can only reproduce the sensation of actual motion in the initial acceleration. It cannot be sustained because of the physical limits of the size of the motion platform. However, the motion sensors of the human body respond to accelerations rather that sustained motion, and so a motion platform can produce motion cueing.
There are three types of tactile sensors. The first, single point sensors, can be compared to a single cell, or whiskers, and can detect very local stimuli. The second type of sensor is a high spatial resolution sensor which can be compared to a human fingertip and is essential for the tactile acuity in robotic hands.
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
Optical flow sensors are also being used in robotics applications, primarily where there is a need to measure visual motion or relative motion between the robot and other objects in the vicinity of the robot. The use of optical flow sensors in unmanned aerial vehicles (UAVs), for stability and obstacle avoidance, is also an area of current ...

Motion update: the robot moves some distance to the left. All particles also move left, and some noise is applied. The robot is physically at the second door. Sensor update: the robot detects a door. It assigns a weight to each of the particles. The particles likely to give this sensor reading receive a higher weight.
