Frictionally yielding media are a particular type of non-Newtonian fluids that significantly
deform under stress and do not recover their original shape. For example, mud, snow, soil …

This paper presents the design and control of Q‐Whex, an untethered, quasi‐wheeled
hexapod robot. Q‐Whex has only six actuators—one motor located at each hip—achieving …

In this paper, a novel transformable leg-wheel mechanism is proposed. It has three active
joints, among which the hip roll joint is directly driven, the hip pitch joint is driven by gear …

Quadruped robots have great agility, flexibility and stability, which enables them to walk
through uneven terrain. Motion control of legged robots is always a difficult problem …

The wheel-legged quadruped robot has high mobility efficiency and strong obstacle-
crossing ability, which combines the advantages of both wheeled and legged robots. Most …

A wheeled robot operating on various terrains such as scattered obstacles and slopes is
required to cope with and overcome the driving environment. In this paper, in order to …

The wheel-legged hybrid structure has been utilized by ground mobile platforms in recent
years to achieve good mobility on both flat surfaces and rough terrain. However, most of the …

Lugged wheels are widely used to increase wheels' traction on sandy terrain such as
planets. It is essential to model the interaction between lugged wheels and sand for …

A wheeled robot operating on various complex terrains with scattered obstacles and steep
slopes must be capable of surmounting obstructions and coping with the extreme driving …

Oscillating propulsion is widely used in underwater robots, which is inspired by the fin of fish.
However, the negative force generated during the locomotion is affecting the propelling …
