Infrastructure-Aided Localization and State Estimation for Autonomous Mobile Robots [PDF]
A slip-aware localization framework is proposed for mobile robots experiencing wheel slip in dynamic environments. The framework fuses infrastructure-aided visual tracking data (via fisheye lenses) and proprioceptive sensory data from a skid-steer mobile

Adaptive control of a skid-steer mobile robot with uncertain cornering stiffness
This paper presents an adaptive controller for a position tracking problem of a skid-steer mobile robot. First, a non-adaptive control law is designed by the backstepping method, where the reference signals are generated by a non-holonomically ...

Analysis of Tread ICRs for Wheeled Skid-Steer Vehicles on Inclined Terrain
The instantaneous centers of rotation (ICRs) for the two treads of skid-steer vehicles moving with low inertia on hard horizontal terrain almost remain with constant local coordinates, which allows to establish an equivalence with differential-drive ...

Deep Reinforcement Learning for Autonomous Dynamic Skid Steer Vehicle Trajectory Tracking
Designing controllers for skid-steered wheeled robots is complex due to the interaction of the tires with the ground and wheel slip due to the skid-steer driving mechanism, leading to nonlinear dynamics.
