Considering the requirements of high scientific return, low cost, less complexity, and more
reliability for the robot proposed by the extreme environment exploration task on the planet …

Spherical robots have fully wrapped shells, which enables them to walk well on complex
terrains, such as swamps, grasslands and deserts. At present, path planning algorithms for …

The hydraulic drive unit (HDU) is the actuator of a legged robot joint, whose control affects
the robot's motion performance. Impedance control is one of the essential control methods …

The use of spherical robots in outdoor operations has increased because they can move on
uneven/three-dimensional (3D) terrain. Since the non-holonomic constraints and the rolling …

In this paper, we propose a fully decentralized control strategy for collective payload
transport in 3D space by a team of identical holonomic mobile robots in a microgravity …

The reliable distributed monitoring system provides the real-time video observation from the
power cable tunnels when the preinstalled communication system is disabled in an …

In this paper, we present a method to model and manipulate a spherical object using a
deformable sheet held by a team of mobile robots. The proposed modeling method captures …

In the recently introduced Variable-Shape heaving wave energy converters, the buoy
changes its shape in response to changing incident waves actively. In this study, the …

More and more robots are required to adsorb or crawl on the 3D curved surface in order to
assist humans in some dangerous or tedious tasks. Existing methods on curved surface are …

This paper presents an adaptive uncertainty estimator-based proportional-integral (PI) type
sliding mode control for a spherical robot with structural uncertainties and external …
