Rimless wheel model

Definition

The rimless wheel model is a conceptual framework used to understand the locomotion of wheeled systems that lack a defined rim around their wheels. This model is particularly significant in studying bio-inspired wheeled locomotion, as it simplifies the mechanics of movement and focuses on the dynamics of rolling without the complexities introduced by rims. It can illustrate how organisms and robots can efficiently navigate their environment by mimicking natural movements observed in certain animals.
