Data-assimilation-based parameter estimation of bathymetry and bottom friction coefficient to improve coastal accuracy in a global tide model [PDF]
Ocean Science, 2022 Global tide and surge models play a major role in forecasting coastal flooding due to extreme events or climate change. The model performance is strongly affected by parameters such as bathymetry and bottom friction.

Friction Estimation for Tendon-Driven Robotic Hands [PDF]
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021 In tendon-driven robotic hands, tendons are usually routed along several pulleys. The resulting friction is often substantial, and must therefore be modelled and estimated, for instance for accurate control and contact detection. Common approaches for friction estimation consider special dedicated setups, where the parameters of a static or dynamic ...

A technical survey on tire-road friction estimation
Friction, 2017 Lack of driver’s knowledge about the abrupt changes in pavement’s friction and poor performance of the vehicle’s stability, traction, and ABS controllers on the low friction surfaces are the most important factors affecting car crashes. Due to its direct

Polyhedral Friction Cone Estimator for Object Manipulation [PDF]
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021 A polyhedral friction cone is a set of reaction wrenches that an object can experience whilst in contact with its environment. This polyhedron is a powerful tool to control an object's motion and interaction with the environment. It can be derived analytically, upon knowledge of object and environment geometries, contact point locations and friction ...

Proposal of the road surface friction coefficient real-time estimation method
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018 For Autonomous Driving (AD) system or vehicle behavior control, it is important to know the friction coefficient of the road surface accurately. It is because the lateral and the longitudinal force characteristics of the tire depend on the road surface ...
