Indoor service robots have been widely introduced in the fields of cleaning, delivery,
education, guidance, and healthcare, etc. in indoor environments. The mobility of an indoor …

This article presents a review of the platform configuration and dynamic of obstacle-
surmounting unmanned ground vehicles (UGVs). For now, unmanned systems have …

Adaptability is a fundamental yet challenging requirement for mobile robot locomotion. This
article presents-WaLTR, a new adaptive wheel-and-leg transformable robot for versatile …

A small-scale jumping–crawling robot expands the accessible region of a robot by
selectively performing suitable locomotion type. However, the parallel elastic actuation for …

Two-wheeled mobile robots with deformed wheels face low stability when climbing steps,
and their success rate in overcoming steps is affected by the trajectory. To address these …

This article presents the design, control, and implementation of a novel four-legged rover for
planetary exploration. A novel active-passive coupled leg mechanism is proposed for the …

Mobile robots can replace rescuers in rescue and detection missions in complex and
unstructured environments and draw the interest of many researchers. This paper presents a …

This paper presents the design, analysis, and performance evaluation of an omnidirectional
transformable wheel-leg robot called OmniWheg. We design a novel mechanism consisting …

Stair climbing is one of the most important capabilities of mobile robots. Therefore, stair-
climbing mobile robots have become a field of study and diverse stair-climbing mobile …

In this study, a modified rocker-bogie mechanism that improves mobility using only two
actuators and a damper is proposed. Previous mechanisms used large numbers of motors …
