Use the robots (blue) to move the blocks (green) to the goal positions (outlined) with the arrow keys (←,↑,↓,→).
Be careful! Brownian noise that is % of control power is pushing your robots.
Real-world microrobots and nanorobots are affected by turbulence caused by random collisions with molecules. These collisions are called Brownian noise. This experiment varies the strength of these disturbances to study how noise affects human control of large swarms.
One way to counter disturbances is to use feedback control: measure the swarm positions, and automatically calculate a new control value based on the current measurements.
See our video on feedback control of living one-celled organisms and paper for details.
