WebOct 26, 2024 · It may also be referred to as odometry. What sensors are used? Robot dead reckoning algorithms generally use wheel encoders, an IMU, and optical flow sensors (like the one in your mouse). Some optical flow sensors for robotics have both LED and LASER light sources which work better on rough and smooth surfaces, respectively. WebOptical tracking schemes are very appealing because they seem more plug-and-play than wheeled odometry, but even field surface tracking using dedicated sensors like ours is still far from perfect.
