www. swarmcontrol. net. The algorithm extends to any number of robots; this video shows a simulation with 120 robots and a more complicated goal pattern.
Our research is motivated by real-world challenges in microrobotics and nanorobotics where often all the robots are steered by the same control signal (IROS 2012 paper).
This steering algorithm is based on piecewise-constant inputs and Taylor series approximations. Taylor series approximations give us a clear method for increasing precision.
The algorithm published in another 2012 IROS article shows that rotational noise improves control but translational noise impairs control.
Our algorithm allowed us to control the final position of n robots but we could not control the final orientation.

But general-purpose image-segmentation algorithms aren reliable enough to produce the very precise models that surgical planning requires.
Human factors Typically, the way to make an image-segmentation algorithm more precise is to augment it with a generic model of the object to be segmented.
That anatomical consistency could give a segmentation algorithm a way to weed out improbable conclusions about object boundaries.
