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...
