tocodometry

Toco-dometry is a novel approach to odometry, the process of estimating the position and orientation of a robot or vehicle over time. It leverages the unique properties of the tocodynamometer, a hypothetical sensor that measures the force exerted by a non-Newtonian fluid against a moving surface. Unlike traditional odometry methods that rely on wheel encoders, inertial measurement units, or visual odometry, tocodometry directly quantifies the interaction between the vehicle's locomotion system and its environment through this specialized fluid.

The core principle of tocodometry involves analyzing the patterns and magnitudes of forces measured by the tocodynamometer as the vehicle moves. These force signatures are believed to be intrinsically linked to the vehicle's velocity, acceleration, and the characteristics of the terrain or surface it traverses. By calibrating these force measurements against known movements, a system can infer the vehicle's displacement and rotation. The complexity of the non-Newtonian fluid and the tocodynamometer's response allows for potentially richer data compared to simpler encoders, potentially offering greater robustness in challenging environments.

Research into tocodometry is theoretical and exploratory. The development of a functional tocodynamometer and the algorithms to interpret its data represent significant engineering challenges. However, the potential benefits include enhanced accuracy in environments where traditional sensors may fail, such as slippery surfaces or areas with significant visual occlusion. The concept also opens avenues for understanding and quantifying interactions with non-standard substrates.
