The leader-follower formation approach is a commonly used strategy in multi-robot systems, usually implemented with hierarchical control architecture combining path planning and control. leader robot determines the desired trajectory while follower robots track motion of using system. However, this does not ensure successful obstacle avoidance for robots. Several solutions proposed adding an la...

We describe an operational program that l o cates objects in a television image and traces their edges. The program accommodates the te levision camera, maximizing dynamic range during acquisit ion and sensi t iv i ty during t racing, to obtain the most appropriate image for each phase. If the trace routine loses an edge, various heurist ics diagnose the d i f f i c u l t y and tune both the ca...

For second-order and high-order dynamic multiagent systems with multiple leaders, the coordination schemes that all the follower agents flock to the polytope region formed by multiple leaders are considered. Necessary and sufficient conditions which the follower agents can enter the polytope region by the leaders are obtained. Finally, numerical examples are given to illustrate our theoretical ...

1. We describe three interneurones and their follower cells in the central ganglionic ring of Helisoma trivolvis. 2. The largest neurone on the dorsal surface of the left pedal ganglion is shown to be an interneurone that contains dopamine and makes monosynaptic connections with a large number of follower cells in the visceral and left parietal ganglia. This neurone is designated as left pedal ...

In this paper design considerations to be used to account for follower jamming of J-equency hopping (FH) spread spectrum systems are presented. A follower jammer attempts to determine the hop frequency with a “determinator” circuit, and then generates jamming in a range about that jiequency. Geometrical considerations show the spatial limit at which follower jamming becomes impossible. The mini...

In this paper, dynamic and stability analysis of a flexible cam-follower system is investigated. Equation of motion is derived considering flexibility of the follower and camshaft. Viscous and Coulomb frictions are considered in the rocker arm pivot. The normalized equation of motion of the system is a 2nd- order differential equation with periodic coefficients. Floquet theory is employed to s...

In this paper, we describe the concept of building a robot able to pursue a specific person through an airport while assisting with carrying that person’s luggage. After a review of the current devices available for performing these tasks, we described our approach that aims to develop a platform that could send and receive a signal that would provide a simple and practical means for the robot ...
