Deep Reinforcement Learning for Autonomous Dynamic Skid Steer Vehicle Trajectory Tracking
Robotics, 2022 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.

Visual-Inertial Localization for Skid-Steering Robots with Kinematic Constraints [PDF]
, 2022 While visual localization or SLAM has witnessed great progress in past decades, when deploying it on a mobile robot in practice, few works have explicitly considered the kinematic (or dynamic) constraints of the real robotic system when designing state estimators.

Slide-Down Prevention for Wheeled Mobile Robots on Slopes [PDF]
, 2017 Wheeled mobile robots on inclined terrain can slide down due to loss of traction and gravity. This type of instability, which is different from tip-over, can provoke uncontrolled motion or get the vehicle stuck.
