This paper deals with navigation problem of wheeled oo-road robots while taking into account the mechanical behavior of the locomotion system and its interaction with the environment. We developed a simulation model of quasi-static motion for a class of wheeled and suspended vehicles. Command velocities are computed by tracking the vehicle control point along the prescribed path. To evaluate th...

We investigate the effect of turning delays on the behaviour of groups of differential wheeled robots and show that the group-level behaviour can be described by a transport equation with a suitably incorporated delay. The results of our mathematical analysis are supported by numerical simulations and experiments with E-Puck robots. The experimental quantity we compare to our revised model is t...

We present a control framework for achieving encirclement of a 3D target using a multi-robot system. Three variations of a basic control strategy are proposed for different versions of the encirclement problem, and their effectiveness is formally established. An extension ensuring maintenance of a safe inter-robot distance is also discussed. The proposed framework is fully decentralized and onl...

There is a growing trend of social robots to move into the human environment. This research is set up to find the trends within social robotic designs. A sample of social robotic designs is drawn to investigate on whether there are more legged social robots than social robots with wheeled. In addition we investigate whether social robots use legs or wheels for locomotion, and which continent pr...

We propose a semi-autonomous teleoperation control framework for wheeled mobile robots with nonholonomic constraints and second-order Lagrangian dynamics over the Internet. The proposed control architecture consists of the two control-loops: 1) local autonomous formation control, which, residing in the common workspace of the robots, ensures rigid formationkeeping among the robots regardless of...

Robot locomotion has been a major research issue in the last decades. In particular, humanoid robotics has had a major breakthrough. The motivation for this study is that bipedal locomotion is superior to wheeled approaches on real terrain and situations where robots accompany or replace humans. Some examples are, on the development of human assisting device, such as prosthetics, orthotics, and...

Robotics researchers have studied the stability maintenance requirements of bipedal robots since they are inherently unstable. An accurate postural stability measure is required to monitor their dynamic equilibrium conditions. In this article, the novel Moment-Height Stability (MHS) measure, which has previously been developed for monitoring the postural stability of wheeled mobile robots, is d...
