An earthworm moves by peristaltic crawling, which propagates extension and contraction waves along the anteroposterior direction from the anterior to posterior part, by varying the thickness and length of its segments. This locomotion mechanism is in contact with a large area on the ground when the robot moves. Furthermore, the amount of space required is less than that for other locomotion mechanisms...
Stability conditions of networked multiple mobile agents in the face of stochastic communications failure are derived. Using a graph-theoretic approach, we provide stability analysis for the case where we employ zero-order hold sampled-data controller and the information of relative positions/velocities are unavailable for certain time instants at each agent. Finally, numerical examples are provided...
A problem of controlling multi-agent systems with intermittent information exchange between the agents is considered. Through energy-based analysis, we first derive stability conditions given a communication network structure and a sampling period. Furthermore, we relate the network topology and control performance in terms of the system's aggregate energy dissipation rate
