The initial location distribution of the nodes is shown in Fig. 1, where the red dots represent the anchor nodes, the green dots represent the unknown nodes, and the color region represents the obstacle area.
From Lyapunov-stability analysis, it is shown that all signals of the controlled closed-loop system are semiglobally uniformly ultimately bounded, point tracking errors converge to an adjustable neighborhood of the origin outside the obstacle detection region, and the obstacle avoidance is guaranteed inside the region.
Their decentralized algorithm requires what they say is significantly lower communications bandwidth, as well as lower computation cost, thanks to the distributed way it makes robots share intel on obstacle-free regions in their immediate vicinity.

The solution domain was divided into variable cylindrical cells near the obstacle (inner flow region), and rectangular cells far from the cylinder (outer flow region), to obtain an acceptable resolution for the entire flow field.
"It is the India-Pakistan relationship that is acting as an obstacle" to the region's uplift, he said.
Iran's Shiite faith is also a serious obstacle in a region where Sunni Muslims are the majority, and sectarian tensions are on the rise.
RIO DE JANEIRO — Iran's efforts to cultivate political support in Latin America at a time of rising international tension over its nuclear program appear to have encountered a significant obstacle: Brazil, the region's economic powerhouse.
For some, CicLAvia is one more annoyance, one more obstacle in a region where traffic is already punishing enough.
