Back again after many, many hours

Another no-scripts bot that will seek out and consume "food" particles without using scripting.

This one uses remote sensing via an internal compass to home in on the food using only mechanics. This means it has a way, way longer range than the other bots since it isn't reliant on an antenna. If its attention is split between 2 particles then it tends to take the middle path until one takes priority (which doesn't usually take long), so it will have curving paths to most ones.

Crank up the sim speed if you can. It takes longer than the others due to the distance between the food.
