Odometry

Basic Odometry Concept

Common Wheel Encoders Magnetic Pickup – used in most ABS Hall Effect Optical

Magnetic Pickup ABS

Incremental Optical Encoder w/ Biphase Output

Systematic Errors Unequal wheel diameters. Average of actual wheel diameters differs from nominal wheel diameter. Actual wheelbase differs from nominal wheelbase. Misalignment of wheels. Finite encoder resolution. Finite encoder sampling rate.

Non-Systematic Errors Travel over uneven terrain Travel over unexpected objects Wheel-slippage Change in tire shape over time
